Abstract:
Industrial activities have a huge potential for waste heat recycling. Recovery of heat and / cold including low temperature is a very important strategy for improved energy efficiency in industry. Heat and cold recovery technologies are instrumental for intra-plant optimisation and inter-plant integration to enable cascade use of heat (or cold) between cross-sectoral plants in industral parks, and with district heating/cooling networks. In spite of its high potential, industrial waste heat is currently underutilized. This may be due, on one hand, to the technical and economic difficulties in applying conventional heat recovery methods and, on the other, the temporary or geographical mismatch between the energy released and its heat demand. Thermal energy storage is a technology which can solve the existing mismatch by recovering the themal waste and storing it for a later use. The heat energy often needs to be transported because the supply of heat is usually located apart from the demand. However, how to efficiently transport the heat energy over long distance is a real challenge. At the same time, there is a great deal of low-grade and middle-grade heat energies, such as solar energy, geothermal energy, and waste heat from industries and power plants, kept unused due to the relatively low thermal grade and long distance to the user sites. Therefore, developing efficient methods to overcome the transportation problems of the low-grade and middle-grade heat over long distance would contribute significantly to the reduction in energy consumption. The case study presented focuses on the possibility of heat waste recovery by thermal energy storage technology and by a new heat transportation concept over long distances.

Keynote: Conversion of landfill gas to drop-in renewable liquid
Time : 09:30 A.M-10:00 A.M
Biography:
Babu Joseph has graduated from IIT/Kanpur with BTech (Silver Medalist) in ChE and obtained his MS and PhD in ChE from Case Western Reserve University. He then joined the Energy Lab at MIT where he has worked on the development of ASPEN Simulator. He has joined the faculty of Chemical Engineering at Washington University in St. Louis in 1978 where he became the Edward C. Dicke Professor in 2000. In 2002, he has moved to become Chair of Chemical and Biomedical Engineering at USF. He is the Author of two books (Real Time Personal Computing,1989 and Techniques of Model Based Control, 2002), one edited volume (Wavelet Applications,1996) and over 200 technical publications. During the year 1985-86, he was a Visiting Professor at the University of California at Berkeley. He is the Founder and VP for Research at T2C-Energy, LLC., a small business working on commercializing technology for converting landfill gas to diesel and jet fuel.
Abstract:
Landfills need robust technology that can efficiently convert the environmentally harmful pollutants found in Landfill Gas (LFG) into harmless products. This LFG also represents a zero-cost feedstock that can be converted into highly desired renewable liquid fuels that are in demand both in-house (diesel for garbage collection trucks) and outside markets (transportation sector). The garbage-trucking sector in the US consumes 1 billion gallons of diesel fuel annually with the average garbage truck using 8,600 gal/year, making up 3% of the total US diesel consumption. This equates to a $3-4 billiondollar expenditure on diesel fuel in this sector alone. USF has developed new catalyst technologies to first convert the landfill gas to syngas using a tri-reforming catalyst and then produce liquid hydrocarbon fuels using a Fischer-Tropsch Synthesis (FTS) catalyst specifically tailored to produce large fractions of middle distillate fuel. T2C-Energy, LLC is working to commercialize this technology. By integrating this technology into gas capturing systems at landfills, landfill sites are able to convert naturally produced landfill gases into liquid transportation fuel (diesel). This technology provides a renewable source of energy while satisfying EPA regulations for reducing landfill gas (LFG) emissions at municipal solid waste (MSW) facilities. This technology produces a renewable, high quality, liquid transportation fuel resembling its petroleum derived counterparts. Thus, existing fuel infrastructure can be utilized in the use (no engine modifications) and transportation of the fuel. By using the green-fuel produced to power the landfill trucking fleet, this reduces greenhouse gas emissions not only from the landfill site but from the vehicles as well. This technology reduces fossil fuel use for the transport of waste to the landfill and drastically reduces the carbon footprint of the entire waste industry.

Erfan Ibrahim,
NREL, USA
Keynote: A systemic approach to cybersecurity
Time : 10:00 A.M-10:30 A.M
Biography:
Erfan Ibrahim works with the public and private sector to identify security requirements; evaluate cyber-security standards; test cyber-security controls; and determine residual risk in smart networks in the electric, water, oil and gas sectors. He also serves on the cyber-security and resilience team within the Grid Modernization Lab Consortium for DOE.
Abstract:
Today's standard based cybersecurity controls for Supervisory Control & Data Acquisition (SCADA) Systems are very IT centric and do little to protect against the Advanced Persistent Threat (APT) from nation states and nefarious organizations that compromise trusted systems and use the security credentials to their advantage. The National Renewable Energy Lab has developed a systemic security architecture that leverages sound network design principles, context based intrusion detection systems and in-line blocking tools to provide an end-to-end security layer across critical infrastructure networks to address cyber-attacks from APTs. In this talk Dr. Erfan Ibrahim, Center Director for Cyber-Physicals Systems Security & Resilience at NREL will provide an outline of this systemic security architecture and explain how this architecture can be used to securely integrate Distributed Energy Resources (DER) such as solar panels, wind turbines, energy storage, electric vehicles and fuel cells to the grid without forcing the power systems to adhere to sophisticated cyber-security controls. This approach will save the electric sector billions of dollars in avoided costs of unnecessary power systems upgrades for improving the cyber-security posture. Purpose built cyber-security technologies maintain the cyber-security posture while leaving the power systems and DER to focus on job of delivering safe, reliable and affordable electricity to the customers.

Mike G Hart
Sierra Energy, USA
Keynote: FastOx gasification: An integrated solution to zero waste
Time : 10:30 A.M-11:00 A.M
Biography:
Mike G Hart, President and CEO of Sierra Energy, has over 24 years of active experience in forming and running industrial companies with a proven record of success. He is a passionate Environmentalist who has been named an “Environmental Hero” by the US EPA and a “Champion of Change” by the Obama administration. He actively works with public agencies- local and regional governments, academia and private industry on regulatory and environmental issues ranging from waste processing and disposal to renewable energy production.
Abstract:
Sierra Energy has developed a technology that makes it possible to eliminate waste disposal in landfills while generating new, salable resources and energy. FastOx® gasification breaks down waste at the molecular level, via ultra-high heat (up to 4,000°F), converting it into energy dense syngas and inert stone and metals. The FastOx system is ideal as an add-on to existing recycling and waste diversion sites, providing the final phase solution for product recovery from remnant and nonrecyclable waste. Sierra Energy’s first commercial-scale system is set to begin operations in 2017. The 10 tonne per day FastOx gasification demonstration system will accept municipal solid waste and biomass, with potential of handling various hazardousnwaste solids, at U.S. Army Garrison Fort Hunter Liggett in Monterey County, California. This commercial size system includes thorough syngas cleaning and conversion to electricity and Fischer Tropsch (renewable diesel additive) liquids. This FastOx system is co-funded by U.S. Army and the California Energy Commission. FastOx gasification involves several processes including waste preparation, gasification, syngas cooling and conditioning and end-product conversion. Waste is shredded, dried and fed into the airlock charging system at the top of the gasifier via a conveyor. Oxygen and steam are injected at supersonic speeds at the base of the gasifier using patented nozzles. The resulting thermochemical reaction converts the waste into syngas at temperatures of up to 4,000°F. Syngas exits the gasifier and flows into the polisher to reform volatile compounds into additional syngas. The stream then travels to the gas cleaning isle, where it is conditioned for final product creation.The remaining inorganic waste melts into a vitrified mixture of stone and metals that is collected from the base of the vessel.The gasifier’s high temperature ensures that the stone and metal are non-leaching and safe for reuse.

University of Tennessee, USA
Title: Economic impacts of producing renewable aviation fuel from cover crops: A case study using pennycress as the feedstock
Time : 2:40 P.M-3:00 P.M
Biography:
Burton C English has been evaluating renewable energy issues since 1978. His areas of concentration include market evaluation, supply chain feasibility and
economic and environmental impacts of the supply chain. These are critical components to evaluating sustainability of the catalytic systems tailored for the
structural features of biomass and its hydrocarbons. Our program evaluates supply chain costs and compares these costs to breakeven analysis of products. In addition, since 2005 we have evaluated the market size for chemical building blocks. Feasibility analysis and tradeoffs analysis between significant environmental and economic variables has been his particular interest. In addition, incorporation of the effects of risk parameters on the supply chain, economic impacts to the communities and techno-economic evaluations of the conversion system have been areas of interest.
Abstract:
In 2015, prior to the climate talks in Paris, the Obama administration wanted to take steps to limit the greenhouse gas emissions from airplanes, after EPA had declared that the aviation emissions contribute to global warming and endanger
human health. EPA deferred any ruling until seeing the report of the UN’s International Civil Aviation Organization (ICAO). The use of renewable jet fuel has the potential to decrease fuel-price uncertainties, thereby decreasing fuel-hedging costs and decreasing profit volatility. The United States Government is actively supporting the development of renewable jet fuels.
As of 2015, the standard setting organization, ASTM International, has approved five renewable jet fuels for use in aviation. This analysis examines the potential for pennycress (Thlaspi arvense) to support a renewable jet fuel industry in the United States. The objective of this study is to examine the economic feasibility of a pennycress to renewable aviation fuel plus evaluate
the potential economic impacts this industry could have on the US economy. To conduct the analysis, two models are used – POLYSYS and IMPLAN. The output from POLYSYS is used to develop economic impact input data for IMPLAN. Partial equilibrium simulation results from POLYSYS suggest that pennycress has the potential to supply approximately 800 million gallons nationally to an alternative aviation fuel industry. The economic impact of this industry has the potential to increase national economic activity by almost $19 billion and add 66,000 jobs. Many of these jobs will occur in rural areas; therefore adding value to pennycress seed by converting the oil into biofuel could enhance rural American economies

Title: Modeling and advanced control of fully coupled wave energy converters subject to constraints: The wave-to-wire approach
Time : 5:40 P.M- 6:00 P.M
Biography:
Liguo Wang has received his PhD degree in September 2017 from Department of Engineering Sciences, Uppsala University and currently is a researcher at the same university. He has seven years of research experience on Renewable Energy with specialization in Ocean Wave Energy. Research covers key areas relevant to wave energy converters e.g. fluid-structure interaction, power take-off systems, energy storage and control strategies. These activities are conducted through analytical analysis, numerical simulation, water tank test of prototypes and sea test of full-scale devices under supervision of internationally recognized experts inwave energy.
Abstract:
Ocean wave energy is a promising renewable source to contribute to supplying the world’s energy demand. The Division of Electricity at Uppsala University is developing a technology to capture energy from ocean waves with a wave energy converter (WEC) consisting of a linear permanent magnetic generator and a point absorber. The linear generator is placed on sea bed and is driven directly by the floating absorber. Since March 2006, multiple wave energy converters have been deployed on the Swedish west coast outside the town of Lysekil. The technology is verified by long-term operation during at sea and satisfactory reliability of the electricity generation. This thesis focuses on developing advanced control strategies for fully coupled wave energy converters subject to constraints. A nonlinear control strategy is studied in detail for a WEC subject to constraints under regular and irregular waves. Besides, two coordinated control strategies are developed to investigate the performance of a wave energy farm subject to constraints. The performance of the WECs using these control strategies are investigated in case studies and optimal PTO damping coefficients are found to maximize the output power. The results show that these control strategies can significantly improve the performance of the WECs in terms of mean power compared to a conventional control. Besides these control strategies, a wave-to-wire simulation platform is built to study the power generation control of the WEC subject to constraints. The wave-to-wire simulation platform allows both nonlinear and linear control force. The results show that there is a good agreement between the desired value and the actual value after advanced control.

Abstract:
Change in energy environment has been rapid in global energy markets. Advanced economies have been trying to build strategic energy technology development copying with environmental changes, their sustainable development and climate change. The strategic energy technology development is crucial factor for leading global green energy markets and
disseminating them in time. In this research, first stage applied scenario planning for making a framework of various scenarios with the upcoming uncertain future of energy environments. We implemented a systematic procedure composed of scenario planning and integrated two multi-criteria decision making approaches, which were the analytic hierarchy process and
TOPSIS methods, to assess 15 energy technologies and prioritize them when decision makers implemented a strategic energy technology development plan as a national level for enhancing national energy security, coping with rapid environmental changes and sustainable development. We made a short-list of 15 energy technologies including energy efficiency technologies, new and renewables and nuclear technology. In this research, we focus on case of low oil price changes and present nuclear power plant status. This research suggests how to find and generate a strategic energy technology development plan considering the selected two key uncertainty variables, including oil price changes and nuclear power plant construction, with STEEP and TOPSIS approaches in the first phase. And then, we build scenario framework considering two key criteria. We assess the case of low oil prices and present nuclear power plant by integrated two multi-criteria decision making approaches for prioritizing short-listed energy technologies. We focus on the strategic energy technology development plan. The results of this research provide decision makers for implementing the uncertain future efficiently with the strategic energy technology development with a scientific systemic procedure.

She is having expertise in microbiology, cell biology and microbial metabolic engineering. Her previous research work focused on exploration of microbial diversity for sustainable environmental solutions. She has published eight research papers in journals of international repute.
Abstract:
Methane, as natural gas or biogas is the least expensive source of biofuel. The main problem with the use of methane is its non-compressing nature. The biological upgrading of this single carbon source to biofuels as well as high value chemicals can bring new sustainable solutions to a number of industries with large environmental footprints. Today, biological engineering has provided new opportunities for metabolic system modulation and give new optimism to the concept of a methane-based bio-industry. The proposed approach is to simultaneously use methanol (MeOH) and CO2 to produce isobutanol with a future goal of going all the way back to the conversion of methane to biofuels. We have engineered E. coli cells to utilize MeOH as acarbon and energy source by expressing methanol dehydrogenase (MDH) and two enzymes from the methylotrophic HuMP pathway. The isobutanol pathway has been integrated into E. coli genome using CRISPR technology. The proposed technology is unique and innovative and has a high probability for commercial success. As global energy requirements change and grow, it is crucial that energy infrastructures need to be adapted and changed to fulfill the promises of increasing population for power generation. Hydrocarbon liquid fuel production from natural gas/methane or methanol will help to replace a significant amount of petroleum-based liquid fuel usage while at the same time will also harvest value from a wasted resource and help to mitigate climate change issues.

Abstract:
In view of the emerging research trend in bio-energy, to circumvent the effects of the impending decline in world’s petroleum reserves and environmental challenges associated with the resource, there is need for African countries to exploit their huge biomass resources towards integrated biorefinery. Nigeria is an agrarian nation with enormous biomass resources that are grossly unexploited for energy generation. Therefore, this present research is investigating the viability of the agricultural residues such as plantain biomass, rice husk, peanut skin and coconut coir from Nigeria for biorefinery operation. These residues were preliminarily analyzed for their monomeric sugar, however, in-depth investigation was focused on plantain biomass due to the enormous yields of wastes from this crop (9,455,000 ton per annual)) compared with other residues under investigation. Our preliminary work demonstrated that the various parts of the plantain biomass namely; flower (inflorescence), leaf and trunk (stem) can be excellent sources of C5 sugars – both in terms of C5 selectivity and yield. The morphology and structural composition of the biomass before and after hydrolysis were studied using SEM and FTIR analysis. The remnant fiber of the biomass was subjected to torrefaction and carbonization processes to produce value-added carbon products such as biochar, carbons for water treatment etc., BET analysis on the produced carbons showed that surface areas up to 900 m2/g can be achieved. Our work showed that developing a plantain–based biorefinery in Nigeria will impact positively on the economy of the nation with significant agriculture based opportunities in the rural areas.

Title: Reliability implications of diversifying wind power resources
Time : 3:20 P.M-3:40 P.M
Biography:
Rajesh Karki (S’98–M’00–SM’04) received his BE degree from the National Institute of Technology, Durgapur, India and an MSc and PhD degrees from the University of Saskatchewan, Saskatoon, SK, Canada.

He was also an Electrical Engineer with Nepal Hydro & Electric, Udayapur Cement Industries, Nepal Tele- communications Corporation and General Electric Canada, Peterborough, ON.
Abstract:
Fossil fuel is presently the major source for electricity production and is believed to be a major contributor to greenhouse gas emissions. Enormous effort has therefore been put on the development and application of green energy sources. Wind is a promising alternative, which has the potential to be a major power source in future power systems. Huge investments are being made in this sector, which has led to considerable advancement in wind power technology. It is expected that wind power installations will grow substantially to produce clean energy in electric power systems. Wind penetration, which is defined as the ratio of the installed wind capacity to the total installed capacity
of a power system is currently about 5% in the Saskatchewan province of Canada. It is expected to increase to over 20% by the next decade. This trend is seen in many jurisdictions around the world. The characteristics of wind power generation is significantly different from that of other conventional generating plants which dictates a need for wind models and techniques appropriately responsive to these characteristics. An increasing number of wind farms located at different sites with varying geographical terrains are being connected to power systems as the wind power penetration continues to grow. The diversity in the wind speed at the various sites can have significant influence on the variability of the overall system generation. This in turn affects system performance and reliability. The wind generation models required for system reliability assessment should therefore appropriately represent the diversity in wind generation profiles. This becomes more important especially at high penetration levels expected in the near future. Time-synchronized data from all the wind farms are generally required to incorporate this correlation in the analysis and hence to accurately model the combined wind generation characteristics. This paper uses an analytical technique to create wind generation models of diverse wind farms and quantifies the reliability benefit to the power system in terms of wind capacity credit and the increase in peak load carrying capability of a wind-integrated power system.

Abstract:
This talk presents some recommendations for the current challenges, development and implementation of renewable energy technologies in the US. Europe has been for several years forefront of renewable energy technology in the world. Europe has presented great innovations in applying sustainable development and renewable energy practices into Europeans daily
life. With the increase in the renewable market in China and the rest of the world, it is essential for US companies to be more involved in the state of the art renewable energy technology in US and around the globe. The challenges for US would be pulling out from Paris agreement, state level not federal level law, inefficient buildings, plants and automobiles, use of fossil fuels, poor renewable energy infrastructure and final renewable energy cost for American family. The opportunities and hope would be DOE’s 20% Wind energy production by 2030 report, renewable energy job creation, 35 states with 70% of the total US net power with the overall target averages 20% of electricity from renewables by 2020 and diversifying risk of energy route by investing in many different states. Last but not least, the author will focus on renewable energy education based on his practical study of solar thermal in Europe and working in US afterwards and will compare the challenges, opportunities and practices of renewable energy and energy efficiency in two sides of Atlantic Ocean and will propose joint European and American renewable energy schools and connection with the European universities counterpart for the joint renewable energy program.

Title: Energy: You don’t know what you’ve got ‘till it’s gone?
Time : 2:20 P.M-2:40 P.M
Biography:
Derek Quinn is the Chief Technology Officer for Why Energy, LLC., an energy consulting and solutions company. His experience includes 28 years as an Engineer and Senior Management for the semiconductor industry in design and development for companies including Texas Instruments, Fairchild, Rockwell and AMCC. Having transitioned to renewable energy technology in 2009, he has developed strategies and an accurate hardware incorporated a software monitoring, analysis and control service system for businesses with sophisticated micro-Grid capabilities.
Abstract:
With apologies to Joni Mitchell, many companies are purchasing energy saving products and are being pursued by companies representing energy components designed be sold on the basis of sustainability and incentives. Businesses that are seeking energy cost reductions rarely know if the strategy they select will financially benefit them or the company that designed and installs their sustainable systems. This article suggests a new strategy to accurately analyze past, existing and future energy costs and develop a control system leading to corporate usage understanding, control and reduction of energy. All businesses understand “you cannot control something you do not understand.” That is particularly true with energy and the related economical management. For example, a relatively efficient hotel may have utility expenses at 6% of their total budget, a food processor probably much higher and a warehouse somewhere in between. An efficient food processor makes
2% to 5% profit on their products. A LED or solar company will target businesses with the goal of selling the product they have on hand as a solution to reducing energy demand and the associated utility cost. LED or solar companies are not in the business of providing accurate long-term studies of energy usage. Their target is to provide products that reduce or offset energy usage. To do more is counter-productive. Similarly, the green sustainable industry cannot survive solely on grants and tax incentives. Addressing 20% of the utility costs through control of energy use can result in a 40% increase in profits with no other change in business operations. There is little benefit for a utility to encourage their customers to reduce usage and degrade their own revenue stream. Unfortunately, cost saving analyses provided by an energy company, is usually spotty, unreliable and often inaccurate.

Time : 2:00 P.M-2:20 P.M
Biography:
August Donat Wojtkiewicz graduated with a Bachelor’s Degree in Economics from Hunter College in 2013. He has taken additional classes online at Harvard, MIT and other institutions. He was Vice-Chair of the Academic Senate at Hunter and a member of Hunter Sustainability Project and CUNY Divest. He advocated for the divestment of City University of New York’s endowment from fossil fuels and was instrumental in getting 15 separate student governments at the University to pass resolutions in favor of fossil fuel divestment. He started a renewable energy startup, LeoVera, in 2015 and would like to transition New York, the United States and the World to 100% renewable energy. He is a rising expert on renewable energy technologies and has participated in numerous conferences on the issue, including The Solar Summit in New York and the Sustainable Energy for All Forums at the United Nations.
Abstract:
Renewable Energy is critical for our future energy needs for multiple reasons. The pressing issue of Climate Change requires that we transition to clean energy sources as rapidly as possible, as well as leave the overwhelming majority of fossil fuel reserves in the ground as a means to slow the rate of temperature increase that we have been observing this over the past century.
The benefits are manifold. No emissions from energy generation sources mean cleaner air, water and land for people and the ecosystem. Free energy sources such as the wind, the sun and the flow of water ultimately mean lower electricity prices for consumers in the long term and increased economic prosperity for society, as funds spent on energy can be invested elsewhere.
The prices for renewable energy technologies are falling year after year and the spread of implementation is increasing rapidly. It is the fastest growing job sector in the United States. New York and other states have set mandates for renewable energy sources. New York is required to produce 50% of its electricity from renewables by 2030. California has set the mandate for 100% renewable energy by 2045. 100% renewable energy is the goal and objective, for individual states, The United States and The World as a whole. The faster we achieve this, the quicker we will see the effects of climate change slow down and ultimately we will see a return to equilibrium planet temperatures if we cease emissions and the use of fossil fuels for energy. Many see this as an incredible opportunity to transform modern society from using highly polluting sources of energy, to using non-emitting advanced forms of clean energy. This means the evolution of our energy technologies and the evolution and modernization of our civilization.

Title: Japanese challenge of introducing renewable energies: Policy, economics, technology and reaction of existing electric power companies
Time : 1:40 P.M-2:00 P.M
Biography:
Akihiro Kogure is the President of LTR Japan Partners. LTR Partners provide consulting service mainly to the energy companies and technology industry. He has established first Japanese electricity power retail company which sells electricity mainly generated from renewable energies.
Abstract:
In Japan, Feed-in-Tariff scheme started from July 2012 replacing RPS and revising existing purchasing scheme for PV electricity. Thanks to FIT, Japanese renewable energy was introduced very much. The most of them are PVs. Government make some amendment on FIT from 2017. Their main purpose is to meet energy mix at 2030 and lower the cost of FIT at the same time. There are 4 main factors: Policy and regulation, Power generation Technology (including cost), Finance and power system. Policy and regulation is the main key. But, many company rely on it excessively. Cost reduction and new business model is highly needed. Finance sector also rely on FIT. But it is also needed to invest new business scheme. Power system in Japan is very different from those in other countries. Inter connection is limited not only with other country but also within Japan. To make maximum use of the electricity generated from renewable energies, the technology and operation policy ofpower system have to be changed dramatically. Technological innovation for smart grid has to be introduced.

Abstract:
We either change and evolve as one global consciousness or we perish as a species, as previous civilizations did before us. The earth will heal itself once we are gone. Collective Cosmic Consciousness is the BioEM quantum energy field; a noosphere created by 6.5 billion people interacting with each other and with nature as one global consciousness. This has been supported by the research by the Noetic Science Institute originated in Princeton University. Quantum physics supports that the entire universe is a projection of consciousness, as documented by the quantum entanglement particle. In Cern, they discovered the “God particle” and research with the double split experiment has proven that we change our reality by observing it. Technology advances exponentially creating our new reality. An evolutionary transformation of humanity is inevitable, as it merges with the technological singularity advancing ultimately to a cosmological singularity. The global fallout and shifts occurring in our world require us to either evolve collectively as one global consciousness or perish. Awakening the collective consciousness is imperative for our survival by developing a new planetary ethical code and creating a new reality. Humanity is required to change dramatically and irreversibly, achieving the next human evolution. To ensure our survival we must make a critical choice now, to be the first civilization to survive on a new viable earth.

Title: Palm oil extraction revolutionary technology
Time : 12:00 P.M-12:20 P.M
Biography:
José Marques is the CEO of IncBio following a course in Economics, in the Faculty of Economics in the University of Porto and after working in two different sectors, he created IncBio in 2006. Focusing on sustainability, his work has been mostly on recycled feedstock. To achieve the best results, he concentrated IncBio’s work in new technologies, using solid catalyst, dry wash resins and mainly Ultrasonic Reactors.
Abstract:
Oil extraction efficiency is the percentage of oil extracted from the total oil available in the total mass, of any feedstock. In the soybean oil industry, efficiency is approximately 95%. In the rapeseed industry, efficiency is approximately 98.5%. In the palm oil industry, efficiency is close to 50%! It is, without a question, the industry with the worst Oil Extraction Efficiency of any oil industry and it represents an unbelievable waste, which has taken a big toll on the environment. With the increase of demand of palm oil in the last decade, for many different industries, the industry has been focusing on plantations, cutting or burning tropical forests, to produce more palm oil. But efficiencies have only marginally increased. IncBio’s technology has been under development for more than 5 years and it has been industrially implemented for 2 years. After the first year of learning from issues that were not expected, the plant has been running for a year with and OER (Oil Extraction Rate) above 25%, when the national average for Malaysia is 20.1%. This represents an Oil Extraction Efficiency of 62.5%, or an increase of 25% over the current technology. While there is still a lot of possibilities for growth, this represents a major step in an industry that is known for hurting the environment. This can actually increase palm oil production by 25%, maintaining the same plantations, without cutting or burning any more trees.

Abstract:
Providing travel-related energy and environmental information to transport users is becoming increasingly relevant. However, the impact of providing such information on users’ travel behavior is yet to be determined. This research examines the perceptions and preferences of the fuel consumption costs, GHG social costs and health-related air pollution costs and the influence such information have on travel behavior. Examining the case of transport users of Montreal, Canada with a pilot survey, we found that the respondents are generally unaware of the energy and environmental footprints of theirntravel. Approximately, 70% of the respondents are not able to estimate GHG social costs and health-related air pollution costs across different modes. The respondents who could provide their perceived costs generally overestimate these costs and interestingly perceive higher environmental costs for public transport (metro) compared to cars. They also prefer to receive such information in monetary units rather than in their own units (e.g., grams of emissions) and they are more comfortable in receiving the information through mobile applications over other tools/means (GPS devices, radio and so on). The research also finds that energy and environmental information can influence respondents’ travel decisions especially their route choices. Finally, the respondents are willing to pay an average of $6/month in exchange for obtaining the information.

Abstract:
The growing demand for high efficient energy utilization of vehicles replaces hydraulic systems with electro-hydraulic actuators. The benefits of the electro-hydraulic system are energy recovery/storage, variable speed, power on demand and reduced emission. In era of electric vehicle, the electronic components (motor, power electronics and battery) for the electro-hydraulic system requires effective, reliable and long-life time technologies. The authors present a recent research on the cooling technology applied for the development of an effective brushless direct current (BLDC) motor which electronically performs rectification without brushes. In general, BLDC motor is well-known to low noise, high durability and reliability. Nonetheless, unavoidable temperature increase during operation reduces the efficiency of the motor due to increased losses. The critical loss is resolved into iron and copper losses in accordance with the mechanisms. In this regard, a numerical model has been developed to simulate the losses induced by temperature increase. The numerical model is validated by conducting experimentation which presents excellent agreement with the simulation results. During the operation of the motor for 20 minutes, the temperatures increase up to 62.3°C and 32.2°C for stator and magnet respectively. The authors also demonstrate air cooling structure to reduce the temperatures resulting in reduced losses, increased motor efficiency and durability.

He has published in recycling and has been a Noted Speaker at the 2015 Southeastern Recycling Conference in San Destin, Florida and the 2015 Georgia Recycling Coalition Conference on St. Simons Island, Georgia.
Abstract:
A common reason given for not recycling is that it is not cost effective and too costly to do. To be successful is easy but one should shift paradigms to make it work. Whether you are an educational campus, training facility or community, it can be done effectively and efficiently. It will take a shift in culture and thinking in the beginning. That first shift is to stop thinking of all solid waste as “trash”, but rather a commodity that has monetary value in today’s market place of shrinking resources. Recyclable commodities such as old corrugated cardboard (OCC), standard office paper (SOP), aluminum drink cans are no different that gold, orange juice or pork bellies, they are sold to those companies that need the recyclables as raw material to keep their mills operating, personnel employed and their products flowing into the stream of commerce around the globe. These recyclable commodities are crucial to saving natural resources when they are processed back into their natural states to begin the manufacturing process all over again. Aluminum can be recycled indefinitely and results in a 95% energy savings and reduces pollution by 95% over tradition saves 4 lbs. of bauxite from being smelting for pound of aluminum recycled. Recycling not only generates positive revenue streams but also saves natural resources but also allows for cost avoidance associated with
traditional waste collection and disposal.

Abstract:
A large portion of municipal plastic wastes consists of significant amount of polyvinyl chloride (PVC) products containing hazardous chlorine element. During their disposal activities such as incineration, a lot of toxic chemicals including hydrogen chloride, chlorine gas, dioxins and furans can be released into environment. Therefore, proper development of selective separation methods of PVC containing chlorine is necessary before applying disposal or material recycling processes. However, it has been difficult to separate selectively PVC from mixtures of plastics having similar appearance density i.e. PVC and PET mixture (PET 1.38 g/cm³ and PVC 1.42 g/cm³). This study presents a one-step selective separation technique of PVC using H2O2 solution to promote hydrophilicity development on PVC surface under ultrasonic irrigation. The ultrasonic treatment helped to decrease air bubbles attachment on PVC surface which can make settling down of treated PVC to the bottom of the flotation reactor. However, the PET treated under the ultrasonic environment was easily floated over because it was still kept hydrophobicity. The combined treatment of low concentration of H2O2 and ultrasonic irrigation for 30 min showed 100% purity and recovery of the PVC separated from PET which could be a suitable and inexpensive way to improve plastic recycling quality through selective separation of PVC with selective building of hydrophilicity on PVC surface.

Abstract:
Geopolymer is a new technology towards greener environment as it utilizes industrial waste like fly ash, metakaolin, blast furnace slag etc in bulk quantity. The geopolymer technology was first introduced by Professor Joseph Davidovits of France in 1978. His work shows that the adoption of the geopolymers could reduce the CO2 emission caused due to cement industries. The development of geopolymer system is an important step towards the production of environment friendly materials. Geopolymerization involves a chemical reaction between various alumino silicate precursors with alkali metal silicates under strong alkaline conditions yielding polymeric –Si-O-Al-O- bonds, which lead to geopolymers by polycondensation. In present research work an attempt has been made to develop high strength geopolymer mortar using industrial waste fly ash from Satpura thermal power plant Sarni (M.P) India and Rice husk from agro industries. Sodium hydroxide and Sodium meta silicate were used as conventional alkaline activator. Rice husk was used for the synthesis of in-situ silicates for development of inorganic organic hybrid alkaline activator. For the first time this inorganic organic hybrid alkaline activator was developed by CSIR-AMPRI Bhopal India for multifunctional applications. Patent filed in India and USA and its application number is 0088NF/2016/201611019506 Dated 30, March 2016. The developed inorganic organic hybrid alkaline activator was used with conventional alkaline activator in different percentages by weight of fly ash. The percentage range chosen were 0.5%, 1%, 1.5%, 2% and 2.5%. Fly ash based geopolymer mortar cubes samples were thermal cured in hot air oven for 48 hours at 600C and then the cubes samples were left at ambient temperature. Five batches of inorganic organic hybrid alkaline activator and one batch of reference conventional geopolymer mortar were mix design and three cube samples for each batch were tested at 3, 7 and 14 days respectively for compressive strength. The conventional geopolymer mortar prepared with alkaline activator of optimized 12.5 molar solution. The compressive strength of conventional geopolymer mortar was found to be 35.9 MPa at 14 days which was compared with the geopolymer mortar developed using inorganic organic hybrid alkaline activator and it was found that maximum compressive strength of 55 MPa at 14 days was achieved after adding 2% of inorganic organic hybrid alkaline activator. The developed high strength geopolymer mortar can be used for production of prefabricated building components

Abstract:
The integrated management of media based (both water and air) pollutants is the vital at current as the management and legalization of individual pollutant is very difficult. Integration of various environmental aspects associated with activities of production processes is one of the challenges in industrial sectors. It is of vital concern to find the scientific way of integration of media based pollutants for today. Based on amount and kind of media based pollutants, Integrated Environmental Performance Score (IEPS) is calculated applying Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI). The potential impacts of individual pollutants have been modeled for water-based pollutants viz., Chemical Oxygen Demand (COD), Total Phosphorous (TP) and Total Nitrogen (TN) and air pollutants viz.,
Oxides of Nitrogen (NOx), Oxides of Sulphur (SOx) and Particles Matter (PM10). A kilogram of individual pollutants is taken in modeling to compute the individual impact categories of unit pollutants. The EPS penalty of TN is obtained as highest score of 189.70 i.e. 90.82% shares among six pollutants. The total penalty score for TP, PM10, TN, NOx and SOx, is derived as 13.53 (6.48%), 2.59 (1.24%), 1.30 (0.62%), 1.30 (0.62%) and 0.44 (0.21%), respectively. Hence, it is necessary to integrate effects of pollutants as per the scientific and justified impact caused by individual pollutants derived from the industrial facilities. Therefore, this study recommends for the compliance of EPS penalty of the pollutants based on a result of TRACI. This helps to enforce a scientific and justified polluters’ pay principle.

Abstract:
Street lighting is one of most critical elements of urban infrastructure. It is a key service that public authorities need to provide for ensuring adequate lighting on roads which leads to enhanced safety and security in the city as well as improving visibility during evenings and night. The use of energy efficient technologies like LEDs has the potential to save costs because of reduction in electricity consumption. In India, the Urban local bodies or ULBs (also called municipalities) are responsible for deploying, maintaining and replacing the street lights. The primary financing options available to finance the lighting upgrades are via internal funding through capital budgets, debt financing or via energy performance contracts with Energy Service Companies (ESCOs). This study takes an innovative approach in conjunction with existing financing mechanisms, by partially utilizing a crowd funding framework to pay for the street lighting upgrades. The three pillars of this proposed model will be: ESCO, Municipality and the Citizens. The success of a Public- Public partnership model can prove to be the cornerstone of other such models in the energy sector. The municipalities can upgrade the infrastructure at no additional costs and simultaneously cut down on their expensive operation and maintenance. After proposing a program structure, this paper will discuss the legal, economic, social and technical factors affecting the feasibility of the proposed structure in the Indian context. This work focuses specifically on tier 2 cities in India, which are defined broadly on the parameters of population (demographics), finance (living costs) and infrastructure (transport systems). This will be followed by a summary of the potential risks and challenges that are inherent in the model and how to address them.

She is presently working as a Junior Research Fellow (JRF) of the University Grants Commission sponsored by Indo-US 21st Century Knowledge Initiative Programme Project No. 194-1/2009., entitled, “Foam –assisted CO2 flooding for the depleted reservoir of Upper Assam Basin and candidate reservoirs in Louisiana”, Department of Petroleum Technology, Dibrugarh University.
Abstract:
In alkaline surfactant enhanced oil recovery (ASEOR) an alkali and surfactant/surfactants are used to recover the residual oil that remains after secondary brine flooding. The alkali, which is Sodium Hydroxide (NaOH) in this case reacts with acidic components in the crude oil to form surface-active substances. A GC-MS spectrum of Upper Assam crude oil reveals the presence of carboxylic acid groups leading to in-situ formation of surfactants which in turn decreases the interfacial tension (IFT) between the oleic and aqueous phases for better oil recovery. While the anionic surfactants used were Black Liquor (BL) and Sodium Dodecyl Sulphate (SDS). The Critical Micellar concentration (CMC) of BL and SDS one at a time was added to NaOH to enhance the effectiveness of NaOH in further decreasing the IFT of the Alkali-Surfactant (AS) slugs. The paper also make an attempt to study the adsorptive nature of the AS slugs. The best fit adsorption isotherm was derived by using SciDAVis scaled Levenberg - Marquaradt algorithm regression co-efficient.

Title: Fischer-Tropsch synthesis of biomass-originated fuels: Reaching the ideal performance in production of high-quality bio-diesel
Time : 2:40 P.M-3:00 P.M
Biography:
Nima Moazami achieved his MEng degree with First Class Honors (Highest Academic Achievement in UK) and received his PhD degree in Mechanical Engineering at University of Birmingham, Birmingham, UK. He has been focusing on three major research projects i.e. Biomass-To-Liquid production via Fischer-Tropsch Synthesis, on-broad catalytic fuel reforming of gas and liquid fuels for hydrogen production and Organic Rankine Cycles for waste heat recovery. He is so determined to excel in these fields and generally in alternative fuels and renewable energies and to continue his work to advance the fields. His goal was always to make and will be making original scientific contributions vital and beneficial to the world as a whole. He has his expertise in mathematical modelling and simulation analysis and passion in production of ultra-clean transportation fuels and reducing emissions of particulate matter, CO and hydrocarbons, SOx and NOx as well as solving the world's current energy problems.
Abstract:
Liquid fuels produced from biomass via Fischer-Tropsch (FT) synthesis have great potential to produce high-performance, environmentally friendly clean and high-quality transportation fuels; mainly due to the absence of aromatic compounds, SOx and NOx. Currently, there are three main aspects for consideration regarding the FT synthesis processes. Firstly, there exists the FT synthesis reaction mechanism, the details of which are still not fully understood. Furthermore, from the outlook of chemical engineering, there is the design and scale-up of the commercial FT synthesis plant in which studies of the comprehensive mathematical modelling of the reactor hydrodynamics, reaction kinetics mechanisms as well as optimization study play significant roles. In fact, to reach the ideal performance of the FT synthesis process, a precise comprehensive mathematical modelling along with chemical reaction kinetics mechanisms that can describe the product distribution of FT synthesis is essential. This research has been focused on production of biodiesel (ultra-clean transportation fuels) from biomass via Fischer-Tropsch synthesis process at the presence of supported cobalt catalyst (37%Co/SiO2). The aim was to
develop a comprehensive mathematical model of a catalytic fixed-bed reactor along with comprehensive chemical kinetics model of Fischer-Tropsch synthesis reaction mechanism in order to investigate the conversion, as well as productivity and selectivity of gasoline, diesel and wax based on required application as this process can play a major role in solving the world's current energy problems and is crucial to industrial practice, being a prerequisite for industrial process design, optimization and simulation. Therefore, a novel kinetic mechanism along with comprehensive novel mathematical model of the fixedbed catalytic FT synthesis reactor was established. The results indicated that the novel developed kinetic model based on a combination of alkyl/alkenyl mechanism for FT reactions (for production of n-paraffins and α-olefins compounds) along with formate mechanism for WGS reaction can provide the most accurate predictions. In order to enhance the performance of the FT synthesis process, first the parametric studies were performed to numerically investigate the effects of operating conditions on the catalytic performance of the fixed bed FT synthesis reactor over 37%Co/SiO2. The reaction temperature, total pressure, space velocity and H2/CO molar ratio were tested to see how effective they are. Those parameters that have the most significant
effects were then included in the multi-objective optimization process in MATLAB programming software using advance Non-dominated Sorting Genetic Algorithm (NSGA–II) to optimize the productivities and conversion. My advance codes and optimization process gave rise to a set of trade-off optimal solutions known as Pareto-optimal solutions. As a result, the Paretofront solutions were established in order to be used as a dynamic database for the specific requirement. Different operating conditions from the obtained database were selected which privileged the optimization of a particular output for example increasing the production of bio-diesel fuel, increasing the conversion rate of bio-syngas species (CO and H2), decreasing of CO2 emissions and decreasing the production of undesired CH4 and lighter hydrocarbon compounds.

His broader research interests include Environmental and EnergyEconomics, Growth Theory, Labor Economics as well as Urban Economics. His work focuses on Energy Consumption and its impacts on the Environmental and Societal Degradation.
Abstract:
Mainstream economists have used various growth models to predict the interaction between sustainable economic growth and the endless accumulation of capital while environmental concerns and their negative externalities are left out in most cases. In this paper, I will present a structural economic model that explicitly allows for the interaction between an economy and an ecosystem. The proposed model indicates that given a wide range of development and socio-economic infrastructure while population growth might be a reason for the constant growth trajectory, it has an adverse effect due to the constraints of resources and the environment. This is because economic activities and population growth increase ecological disordering as they downgrade the environment, while the later element has a negative impact on living standards. Considering different scenarios of utilizing renewable energy for economic growth, a feasible endurance factor for sustainable development might promote the methods of using the substituted energy and recycling methods. This, however cannot be accomplished given the current speed and direction of technological progress and energy utilization and waste management

Belqasem Aljafari has completed his MS from Northern Illinois University School of Engineering. He is pursuing his PhD degree from School of Engineering.
Abstract:
Throughout the whole world, there are isolated areas where access to an electricity grid is too expensive. Diesel generators have been widely used for a long time because of the low initial cost but at the same time, they have high running and maintenance cost. As a matter of fact, the diesel generator has many impact factors towards the environment such as producing of CO2 gas. Therefore, to avoid environmental pollution, global warming and ozone layer damage renewable energy sources are the appropriate alternative sources. With all renewable energy sources such as wind, solar and geothermal, solar photovoltaic energy is primarily used because of its clean, pollution-free and inexhaustible nature. In the Middle East, especially in Saudi Arabia, the hot outdoor climate induces a necessity for cooling inside the buildings. Particularly, the solar radiations are significant throughout the whole year. Using air conditioning is very common in Saudi Arabia and sometimes overused, leading to high peak loads for the electricity grid. Hence, the idea is to use the energy from the solar radiations to run the appliances and air conditioning system to reduce the peak demand on the electrical grid. In addition, when using solar panels, it is preferable to immediately use the solar energy than to keep it for later. Therefore, as to avoid using much electricity from the grid at night to run the chillers, the idea is to produce and store during the day by having the battery backup system.

Abstract:
Statement of the Problem: The global energy prospective is quiet fluctuating. The energy markets are moving towards technological growth and environmental concern. In this aspect, Microbial fuel cells (MFCs) for conversion of organic matter into electricity for recovering green energy are becoming significant. Soil has been used to generate electricity in MFCs and shown several potential applications in today’s world. Whereas, usage of dried leaves having a high source of organic content with soil types in an MFC is not studied before and it is novel. The main aim of this study is to address the effect of soil types on the electricity production, nitrogen cycling and greenhouse gas emissions from MFCs loaded with dried leaves.
Methodology: Experiments were carried out in single chambered MFCs equipped with air cathode and carbon felt anode operated for 109 days at room temperature. Two different soil types such as sand and clay were used. Dried leaves were collected from Morgan Arboretum forest reserve, McGill University, Canada. Voltage readings with 500 to 1150 Ω external resistances were measured continuously for study period. MFCs were monitored regularly for gas emissions and changes in nitrogen compounds.
Findings: Sandy soil used in the study had 100% sand and clay soil had 40% clay, 38.5% silt and 21.50% sand. Dried leaves had 72% of organic matter with 42% of carbon content. Both MFCs with sand and clay soil with dried leaves gave continuous electricity production throughout the study period with maximum power density of 29.2 mW/m3 (1.9 mW/m2) and 23.8 mW/m3 (1.6 mW/m2), respectively. Clay soil MFC had higher methane emissions (27%) than sandy soil. Nitrogen profiles showed nitrogen uptake by soils and its possible nitrogen pathways. Conclusion & Significance: The study demonstrated that the soil types with dried leaves have significant impact on electricity generation and nutrient cycling in MFCs. It has potential for production of renewable energy and climate change mitigation.

Abstract:
The environmental issues such as global warming, climate change and environmental pollutions are defining challenges for the 21st century. Studies show that the reduction of the energy demand for heating and cooling as the most energy consumers in building sector, is the key factor in the low energy houses. This paper focuses on the courtyard housing typologies, which were traditionally known for their distinctive passive cooling performance and can contribute meaningfully towards achieving a sustainable building design with high energy efficiency in all regions particularly in hot-arid climates. The goal is to propose an optimized low-energy design model for courtyards regarding orientation, geometrical properties and the materials, to provide the maximum thermal comfort for residents. After a comprehensive literature review, the Design Builder software package was employed to develop a three dimensional numerical building model to simulate a courtyard house in BW climate of Phoenix in Arizona as a research case. The model was verified using data from previous research including indoor and outdoor temperature and residents’ thermal comfort and close agreement was achieved. The effects of three main design variables were studied including orientation, geometrical properties (dimensions and proportions) and materials, on residents’ thermal comfort in the courtyard to achieve most efficient design. Interactive correlations between the design variables were quantified and an optimization was conducted using Rhinoceros plug-in Grasshopper in order to maximize thermal comfort for residents and minimize energy consumption related to building heating and cooling. A nonlinear equation were derived based on the optimization investigation to be used in designing courtyard houses in hot-arid climate which can aid designers to design most-efficient low-energy courtyard houses in this region.

Title: Moving towards zero waste in South Asian cities
Time : 4.40 P.M - 5.00 P.M
Biography:
Bedoshruti Sadhukhan has a Master’s degree in Environmental Management and more than 12 years of experience in project management, training and capacity building in the field of environment management, environmental justice, environmental impact assessment, public participation in decision making, water, waste and climate resilience. She has also worked on Human Rights Issues such as housing rights and tribal rights. She is a Key Member of the ICLEI South Asia
sustainability team and manages long term international projects on environmental management systems for local governments, climate resilience, water, sanitation and solid waste management in South Asian countries.
Abstract:
With increasing population, economic development and a growing consumerism, South Asian cities are facing a significant change in waste generation and its characteristics. Managing waste has always been the responsibility of local authorities (LAs), but the age-old practice of dumping waste is no longer sustainable. It is an inefficient way to use limited land resources causes environmental pollution of soil and ground-water, social impacts through health issues of nearby communities and is an overall unsustainable practice leading to loss of valuable material resources. Obviously, LAs need to look for sustainable options of reducing, reusing and recycling waste. Integrating the existing system of informal waste-pickers in South Asia, who dominate recycling even before the waste enters the formal management system can lead to significant environmental (material recovery), social (health) and economic (livelihood options) benefits. ICLEI South Asia conducted a project in 7 South Asian LAs encouraging them to promote waste segregation and recycling particularly through informal sector, to move towards a zero-waste community. Successful pilot projects in the cities, demonstrated how recycling helped to reduce waste going to landfills, produced resource materials including compost and generated livelihood for waste-pickers in the city. Continuous engagement with local communities and waste pickers ensured the continuity of the pilots even beyond the life of the project. Critical to successful recycling is simultaneous segregation of waste at source which relies heavily on the awareness levels of community as well as well-established linkages with recycling units which will take up the segregated recyclables. Moving towards zero waste in cities needs collaboration with state and national government agencies so as to incorporate all types of waste, since LAs are only responsible for municipal waste which technically excludes medical waste and hazardous waste but which are major components of the waste coming out of cities.

Title: Recycling paddy husk for improving plant growth yield and disease resistance
Time : 5:00P.M- 5.20 P.M
Biography:
Ruwani Kalpana Jayawardana has experience in using silicon sources both chemical and natural for enhanced growth and disease tolerance in plants. She has a passion in improving plant growth performances by environmental friendly sources and utilizing agricultural waste for improving soil physical, chemical and
biological properties. She has contributed to develop a cost effective hydroponic nutrient solution with silicon. In her MPhil research study, she has found that a low cost simplified hydroponic system with paddy husk in the media as effective way of Si nutrition to enhance anthracnose disease resistance in capsicum.
Abstract:
Statement of the Problem: Paddy husk (PH) is an agricultural waste which has not been utilized properly worldwide. Mostly it is left unused as waste or simply burned in the field creating significant environmental problems. It is expected to have about 700,000 tons of paddy husk production in Sri Lanka in year 2020. PH is an organic nutrient source particularly rich in silicon. Methodology & Theoretical Orientation: Experiments were conducted to investigate the effect of incorporation of PH in the growing substrate to improve plant growth, yield and disease tolerance. A simplified hydroponics system (SHS) with PH and sand (3:2 v:v) media was tested on capsicum plants. In addition, the effect of amendment of soil media with different ratios of PH was investigated on Capsicum annuum L. The effect of amendment of potting media of rubber nursery plants with 20% of PH charcoal or PH ash was also studied. Findings: More than 50% of soluble Si was detected in the nutrient solution of SHS as measured by colorimetric method. SHS was effective for increasing fruit length, fruit weight, shoot length, root length with 83% of reduction of anthracnose disease. In the pot experiment, it was revealed that incorporation of 60% of PH in to soil would be effective for reducing anthracnose disease of capsicum. Significant improvement of plant diameter was reported in rubber nursery plants when potting media was amended with either PH charcoal or PH ash. Conclusion & Significance: In case of anthracnose disease of capsicum use of PH would be an environmental friendly control measure. The findings open path for future investigations on the effect of different forms of PH for enhancing performance of different plants. Further investigations should be conducted to find the vital nutritional potentials of PH and prevent it disposing as waste

Abstract:
Climate change is affecting birds worldwide. Such impacts have always been prevailing due to rising temperature or unpredictable rainfall that might be too abundant or little and which in turn bring about dire consequences upon the lives of the endemic bird known as Bali Myna (Leucopsar rothschildi). In this paper we propose a framework analysis describing the possible patterns of change in the distribution of Bali Myna (Leucopsar rothschildi) population based on climate parameters such as temperature, rainfall and humidity in hope to better have an improved quantitative methodology meant to identify and describe these patterns. This study uses a descriptive qualitative method recoursing to focus upon sites observation and a deep interviews to be carried out while using SPSS 16 in order to know the variables correlation in hope to determine the plausible significance between them that allow us to analyse the effects of environmental variables on bird species in this study. We tested the proposed methodology using data from the West Bali National Park and the existing data of climate variables over the last decade where climate variables are considered to be significant factors influencing the lives of Bali Myna (Leucopsar rothschildi). This study discovers that increases in temperature and precipitation each year have adversely affected the number of Bali Myna (Leucopsar rothschildi) population indicating that the bird’s survival capacity depends largely much on temperature. Besides, it has been perceived that Bali Myna is very reproductive in rainy season but its fluctuations whether high or low impacts them as well. The distribution mapping show a decline of population in 2006 while an increase was perceived during the last five year period of 2011-2015. Besides, over the same period, a slight increase of 0.4 °C in mean temperature was noticed precisely in Cekik our research site where Bali Myna (Leucopsar rothschildi) are.

Kamil Dydek received graduation from FPAE WUT in 2015 and has started his PhD at Warsaw University of Technology in the Department of Materials Science
and Engineering, Poland.
Abstract:
From the environmental point of view there is a great interest in a recycling of packaging foils. Most of them are based on glycol modified poly (terepthalate ethylene)-PETG- printed with colorful inks. Therefore, there is necessary to rinse out inks from the foils first to make them processable. In the first step, the waste foils coming from different producers were characterized in terms of their structure and composition. It was found that they are similar to each other and that is possible to wash away all of the colorful inks in one shot with the appropriately selected medium. The comparison of properties of the foils before and after washing showed that there is no effect of the solvent used. In the next step the transparent foils after washing were dried and processed directly by the twin screw extruder machine in laboratory scale. Based on the results from thermal analysis (TGA, DSC) and rheological behavior (MFI index, shear modulus, complex viscosity) the processing conditions have been optimized. Finally, the effect of different processing temperature and number of cycles on properties of regrind material was investigated. The aim of the study was to analyze the possibility to use regrind PETG foil as a raw material. It would be add to pure PETG to decrease the costs of production or to mix with e.g., nanoparticles to provide new properties

Title: PAdeCS®, a new type of material derived from concrete sludge and its applications to pollution prevention processes
Time : 10:00 A.M-10:20 A.M
Biography:
Akihiro Yamasaki is Professor at the Department of Materials and Life Sciences of Seikei University, Tokyo, Japan. He has his education in Chemical Engineering at the University of Tokyo and awarded PhD in Chemical Engineering for his work on membrane separation. After that, he joined the National Institute of Advanced Industrial Science and Technology (AIST) until he moved to Seikei University. In the meantime, he joined Institute for Environmental Chemistry at the National Research Council, Canada as a Guest Researcher and the Department of Chemical System Engineering at University of Tokyo as a Guest Professor. His research field covers wide range of environmental issues including recycling, CO2 mitigation, water treatment and air pollution.
Abstract:
A new type of material PAdeCS®, derived from concrete sludge has been developed and its removal performances for heavy metals and toxic anions such as arsenate, boron were examined. Concrete sludge is waste of fresh concrete, which is rich in calcium and strong alkaline. Concrete sludge is generated when unused concrete is returned from construction sites or excess concrete in the concrete-using industries. In Japan, the annual emission rate of concrete sludge is as large as several millions metric tons and it requires an acid treatment to neutralize the alkaline components before disposal. We have developed a method for manipulating concrete sludge to prepare a solid material through partial removal of calcium contents to avoid hardening of concrete. After solid-liquid separation, the solid residue was obtained, which is still rich in calcium and alkaline. PAdeCS®, so prepared have versatile usage including heavy metal removal and toxic anion removal from waste water.
In addition, calcium and alkaline in PAdeCS® would form hydroxyapatite (HAP) when mixed with dissolved phosphorus ions. Thus, PAdeCS® can be used for phosphorous recovery process from sewage stream. We first tested the removal performance of boron and fluorine in water. Since PAdeCS® is derived from hydrated cement, it would contain a certain amount of ettringite, a crystalline material with the chemical formula, Ca6Al2 (SO4)3(OH)12•26H2O of which sulfate ions have anion exchange capacity with ambient anions. The experimental results showed that boron as well as fluorine in water can be removed efficiently. In addition, removal of heavy metals and arsenate in water was examined and showed excellent removal performances. Thus PAdeCS® is a versatile solid material for environmental-related applications.

Title: Emissions of VOCs from polymers during their life cycle and risks for use and recycle
Time : 10:20 A.M-10:40 A.M
Biography:
Miyuki Noguchi is a Research Scientist working at Seikei University, Tokyo, Japan. She also teaches classes in the university as a Lecturer. She has obtained
her PhD at the University of Tokyo for Environmental studies. She is an expert in the Environmental Chemistry, especially in the field measurements of VOCs and
SVOCs in the air and evaluation of the air quality.
Abstract:
We measured the emissions of VOCs from polymeric materials such as PVC, PP and PE under various environmental conditions. We prepared a passive type flux sampler made of a glass petri dish of which the inner diameter is 22 mm and the height is 5 mm. A fixed amount of Tenax GR powder is placed on the inner bottom of the sampler as an adsorbent for capturing VOCs. A sheet of a target polymeric material was placed on the sampler for a given period under constant temperature condition. The VOCs emitted from the polymeric sheet diffused through the sampler space and were captured onto the adsorbent. The captured VOCs were then analyzed by the ATD-GC/MS technique to determine the composition and the emission rates. The temperature was change in the range of 25°C (room temperature) to 75°C and the sampling period was set 24 hrs. To examined the time-course of the VOC emission behaviors, the test polymeric materials were left under the same conditions up to 4 weeks and the emission measurements were carried out every 1 week. The total VOC emission (TVOC emission, reduced to toluene) of soft PVCs were much higher than those from other polymers such as PE, PET and we focused on the emission from soft PVCs with different properties. The major VOCs emitted from soft PVC were phenol, 2-ethylhexanol, DEHP and aliphatic hydrocarbons. DEHP is intentionally added to PVC as a plasticizer and 2-ethylhexanol was supposed to be a product of dissociation of DEHP. The emission rate of each component showed a time change as well as temperature dependency. The emission of phenol decreased with time and that of DEHP decreased at first 3 weeks but increased after 4 weeks. The temperature dependence of the emission rates can be expressed by the Arrhenius type equation and the apparent activation energy was determined. These results could be useful for the evaluation of life-cycle risks caused by the use, recycle and reuse of polymeric materials used in commercial products.

Abstract:
Combustion of coal and municipal solid waste (MSW) causes air pollution and produces solid residues which contain high levels of toxic elements. The toxic characteristics of residues generated from combustion of MSW in waste-to-energy plants are strictly controlled by Federal and State Waste Management Regulations. According to Resource Conservation and Recovery Act (RCRA), residue generated from combustion of MSW is considered hazardous and must be tested according to EPA Toxic Characteristics Leaching Procedure (TCLP) Method 1311 and suitably treated for its safe disposal to landfills. Experiments with various treatment chemicals as primary independent variable had earlier been conducted by several agencies and facilities. The author has successfully developed two new cost-effective solutions for stabilizing heavy metals in MSW residues to cover the gap between the leachability concentrations of toxic elements observed in residues and the leachability toxicity limits as per EPA's regulatory threshold. These methods include treating MSW residue fly ash (FA) with 2% dolomitic lime by weight or by injecting aqueous (39% concentration) sodium sulfide at a controlled rate. The extensive full scale experimental study was carried out at 240 t/day capacity Hampton/NASA waste-to-energy mass burn MSW incinerator (MSWI). This process has showed savings to the extent of $150,000 per year by treating the plant's combustion residues with aqueous sodium sulfide over the use of dolomitic lime for ash treatment. The treatment method invented has also shown better control of the leachability of toxic heavy metals than previously used chemical treatment methods. Comparative study showing the level of leachability of toxic heavy metals with different treatment methods has also been studied and the best management practices for use and disposal of such wastes have been discussed.

His research interest is in soil and environmental pollution.
Abstract:
Water quality assessment of inorganic pollutants in some rivers and streams of four different locations (Sokori, Gbangba,Kobiti and Oke-Ijemo) within Abeokuta metropolis was investigated to determine the extent of pollution in these settlements for environmental quality and sustainability. The pH, acidity, alkalinity and metals like chromium, iron, lead and zinc were analyzed using standard laboratory methods. The results showed that the pH of most of the water samples were slightly alkaline with the exception of Oke-Ijemo stream which was slightly acidic but the values obtained fell within the WHOstandards. Sulphate and phosphates were not detected at all in the rivers Sokori and Gbangba as well as Oke-Ijemo stream but were detected in Kobiti stream which fell below the permissible limits. Iron and zinc were present in all the locations investigated with three out of the four locations having iron concentration above the permissible level and zinc concentrations were below the WHO standards. In conclusion, there was no pollution of the water bodies therein with the exception of iron and hence water sources investigated could be generally considered fit for industrial, domestic and aqua-cultural purposes
but for human consumption adequate treatment with appropriate chemicals should be carried out before to prevent outbreak of water borne diseases among the living populace in these areas. However, people residing in these communities should be advised on indiscriminate dumping of any refuse and domestic wastes into the water bodies so as to prevent environmental
pollution and health related hazards.

Abstract:
A wide range of environmental factors including heavy metals stress stimulates oxidative stress. So, antioxidant resistance mechanisms may provide a strategy to enhance metal tolerance by minimizing the toxic effects of reactive oxygen species (ROS). In the present investigation, the effects of heavy metals producing antioxidative defense systems i.e. Superoxide dismutase, Peroxidase and Catalase were studied in the potato plants grown in soil polluted with heavy metals (Cr, Cd, Pb). The results showed that the tannery effluent was highly toxic with high values of all pollution parameters (pH, TDS, NaCl %, ECe, bicarbonates, chlorides). Amount of heavy metals was also high in the effluent and increased with increasing the concentration of effluent. Amount of chromium was the maximum as compared to other heavy metals. Four concentrations of tannery effluent (0, 2, 4, 6 and 8%) were prepared with normal garden soil along with the two treatments of ascorbic acid i.e., 0 and 0.5mM. The maximum biomass was observed in the control and it was decreased with the increasing effluent concentration. The exposure of plants to the highest concentration (8%) reduces the height of shoot. Among the treatments, 0.5mM was observed to show the best tolerance and growth properties with respect to metals. The antioxidant enzyme activities wereincreased by metals stress. The present investigation revealed that the ascorbic acid treatment by foliar spray on the growing plants of potato could enhance the efficiency of antioxidants that significantly reduce the toxic effect of metals from tannery effluent amended soil. The antioxidative activity seems to be of primary importance for adaptive response of potato plants against ROS produced under environmental stress.

Title: Recycling of machining waste by laser metal deposition
Time : 12:00 P.M-12:20 P.M
Biography:
Khalid Mahmood has done his PhD in Mechanical Engineering from The University of Manchester, UK. His main research area is laser metal deposition. The work is novel in the sense as the machining swarf has been investigated extensively as an alternative feed material in laser cladding of protective coatings as well as to build 3D structures. This is an attempt to address optimal utilization of enormous material waste in machining. On the other hand it tackles to obviate the huge cost of raw metal powder used in laser metal deposition. The findings of the work with recycled material are quite encouraging and are comparable with the conventional raw metal powder.
Abstract:
Metals are used extensively in production and have wide applications. Extraction and processing of mineral resources consume a huge amount of energy and steel being the most widely used metal is responsible for the single largest share of the energy consumption all over the world. In manufacturing, machining is a metal subtractive process and produces a large quantity of chips/swarf. Efficient recycling of machining waste can save a lot of energy as well as its effective disposal. This necessitates developing an efficient way to take the chips and recombine them into a block or useful shape for further applications. The processing method should not involve remelting in furnace as this has low efficiency and creates problems related to ambient pollution. Laser direct metal deposition (LDMD) is an additive manufacturing technique which uses material efficiently. In LDMD, injected metal powder is laser melted and fused to the substrate and subsequent layers. Quick solidification is achieved by the local heating and by traversing the substrate. However, the high cost of raw metal powder is one of the barriers to use of this technique on a wide scale. A possible solution to the problems of machining waste recycling and high cost of LDMD powder is to consider machining swarf as an alternative build material for LDMD. This paper illustrates the viability of laser metal deposition of carbon steel machining swarf with nonstandard particle size and shape. Particles of unprecedented size and shape have been deposited and the feasibility of using this kind of build material has been established following analysis of different outcome parameters including clad geometry, microstructure and other physical properties. The results suggest that this recycling technique could with further development reduce demand for raw material and the energy required to extract and refine it.

Title: Demonstration of an energy-efficient and socially fair neighborhood development based on electricalthermal interconnection systems
Biography:
Sebastian Junghans has studied business informatics and completed it in 2012. He, then began his scientific work at the University of Applied Sciences at Zwickau. He has started in Product Lifecycle Management (PLM). The center of this research work was the integration of design and work planning, the use of naturalanalogue algorithms for automated order processing as well as shortening the "time-to-market". The use of techno-economic systems to increase energy efficiency in interaction with smart metering, smart home and smart grid forms was the next research topic. He is currently working on interconnection in the residential district and Big Data.
Abstract:
The project "Demonstration of an energy-efficient and socially fair neighborhood development based on electrical-thermal interconnection systems" is a project initiated by the city of Zwickau in cooperation with scientific and economic partners. The main goal is to develop technologies and methods for the local energy transition, especially the local heat transition and to demonstrate this as a real laboratory in a suitable district in Zwickau. The conception and implementation of electrical-thermal interconnection systems is the basis for an energetic development in a district for the realization of a zero-emission-city. This requires highly efficient storage technologies and the combination of electrical and thermal overall concepts. This makes it possible to increase the share of renewable energy sources such as photovoltaics and in particular solar and geothermal energy in residential districts. Due to the demographic structure found in Zwickau, the city is already closer to the future - whether it is the population structure or the comparatively high technical start level due to the numerous projects carried out in this environment. Within the framework of this project, municipal projects such as climate protection concepts as well as scientific projects of the University of Applied Sciences Zwickau and their partners can contribute to an energy-efficient and social development. Social welfare plays a special role in priority regions such as Zwickau. In this inter- and transdisciplinary project, it is indispensable to pursue a user-oriented and centered technology development. The aim is to secure the affordability of housing by means of new technologies and economically viable concepts as well as social science methods. It is our goal to secure affordable and sustainable habitation by creating new technologies, commercially viable concepts and methods derived from social science.

The offshore wind farm project in South Korea progressed and is targeted to reach more than 2,000 MW for developing a large-scale complex. The project could have influences such as physical, chemical, geological and biological effect on marine environment. The various impact factors such as noise, vibration and electromagnetic-fields are known to be major influencing factors on fisheries resources and marine organisms. Since the relationship between influential factors – the environmental impacts has not been clarified, difficulties in the acceptability of residents and the process of assessing the sea area utilization. There are no methods for biological impacts and risk assessment to noise, vibration and electromagnetic fields on the offshore wind farm project. While the developed countries assess various impacts on individual organisms, there is limit to interpreting results and determining risks. This study aims to propose bioassay methods and risk assessment methods suitable for Korean offshore wind farm projects. We will develop bioassay methods for field organism in the project area and prepare a risk assessment system to improve the acceptance of residents. Through the developed bioassay methods and risk assessment methods, we expect that this project will be carried out scientifically and systematically and become a project that residents empathize with.

Abstract:
Environmental concerns regarding greenhouse gas emissions and depletion of fossil fuel deposits have driven significant research and development into alternative, clean energy sources. Fuel cells present very promising technologies mainly due to the fact that their electricity generation is not based on a heat engine which requires a working agent. Additional benefits could be obtained through combining fuel cells with gas turbines which could theoretically achieve very high efficiency over 70% though not proven to date. Thus, improving the performance of a hybrid solid oxide fuel cell gas turbine system is still under investigation. This can have done by estimating the geometric parameters of the turbomachinery components which shows a clear efficiency advantage for the whole operating range. This review work presents a comprehensive survey of the literature on cryogenic separation of anode off gas for fuel cells. First, the current status of anode off gas separation is assessed. Second, possible techniques are discussed in detail. These include the thermodynamics and heat transfer aspects of the solution. Thermodynamic relations are given for pure hydrogen as the fuel and then gas mixture as the fuel. CO2 capture by chemical or physical sorption and membrane separation have been the dominant fields of research within post- and pre-combustion CO2 capture from power cycles and industrial processes. For a selected range of conditions, potential applications for anode off gas cryogenic separation have been evaluated with respect to energy consumption and profits obtained. For all applications of anode off gas cryogenic separation, specific power consumption and obtainable fuel savings are sensitive to flue-gas or synthesis-gas. However, for certain applications anode off gas cryogenic separation shows promising potential and highly competitive energy figures compared to baseline technology giving an increase in efficiency of 29.58% relative to base values.

Abstract:
Statement of the Problem: Due to the limitation in natural energy resources and the growing concern for environmental protection, alternative power generation technologies have become very important. The perovskite structures have been research subjects for photoluminescence, electroluminescence and catalyst applications. The objective of this study has been to develop less toxic, water-based processes for high efficiency perovskite solar cells. It is therefore essential to design and match the energy levels and interfacial characteristics between the perovskite sensitizers and the contact metal layers. Methodology & Theoretical Orientation: Fluorine-tin oxide-coated glass substrate was cleaned, then surface-treated with plasma and UV light irradiation to increase its hydrophilicity. The electron-transport layer composed of titanium dioxide dense layer and then a mesoporous layer was spin-coated and further annealed. A precursor solution of lead nitrate was used to plate lead dioxide film which was immersed in MAI to create the MAPbI3 perovskite nanostructured thin film. Spiro- OMeTAD was used as the hole-transport layer and silver was applied as the cathode.
Conclusion & Significance: Since developing less toxic, water-based precursor formulation it has been encouraging to find better deposition method for lead precursor, thus the perovskite nanostructure. After the parameters have been optimized, long time stability characterization could be carried out for the new high efficient perovskite solar cells.

Title: Utilization of green plant resource- example of herbal medicine
Biography:
Yang L is a last-year PhD student at China Pharmaceutical University. Her research interest is on the utilization of green plant resources, focusing on traditional Chinese medicine.
Abstract:
Licorice derived from the roots and rhizomes of Glycyrrhiza uralensis Fisch. (Fabaceae) is one of the most widely-used traditional herbal medicines in China. It has been reported to possess significant analgesic activity for treating spastic pain. The aim of this study is to investigate the spasmolytic molecular mechanism of licorice on oxytocin-induced uterine contractions and predict the relevant bioactive constituents in the aqueous extract. The aqueous extraction from licorice inhibited the amplitude and frequency of uterine contraction in a concentration-dependent manner. A morphological examination showed that myometrial smooth muscle cells of oxytocin-stimulated group were oval-shaped and arranged irregularly, while those with a single centrally located nucleus of control and licorice-treated groups were fusiform and arranged orderly. The percentage of phosphorylation of HSP27 at Ser-15 residue increased up to 50.33% at 60 min after oxytocin stimulation. Furthermore, this increase was significantly suppressed by licorice treatment at the concentration of 0.2 and 0.4 mg/mL. Co-localization between HSP27 and α-SMA was observed in the myometrial tissues, especially along the actin bundles in the oxytocin-stimulated group. On the contrary, the co-localization was no longer shown after treatment with licorice. Additionally, employing ChemGPS-NP provided support for a preliminary assignment of liquiritigenin and isoliquiritigenin as protein kinase C (PKC) inhibitors in addition to liquiritigenin, isoliquiritigenin, liquiritin and isoliquiritin as MAPK-activated protein kinase 2 (MK2) inhibitors. These assigned compounds were docked with corresponding crystal structures of respective proteins with negative and low binding energy which indicated a high affinity and tight binding capacity for the active site of the kinases. These results suggest that licorice exerts its spasmolytic effect through inhibiting the phosphorylation of HSP27 to alter the interaction between HSP27 and actin. Furthermore, our results provide support for the prediction that potential bioactive constituents from aqueous licorice extract inhibit the relevant up-stream kinases that phosphorylate HSP27

Abstract:
In Costa Rica there is a great variety of agricultural residues that are presenting an environmental problem. Due to this, two of the main residues have been studied: coffee pulp and pineapple stubble for energy purposes. For this purpose, pellets were obtained from them and from a mixture made up in a 50:50 mass ratio of each residue. The study was performed under different values of moisture and particle size for each pellet processing. Unit density and apparent density were determined with values between 1.09 kg/dm3 to 1.32 kg/dm3, 555.30 kg/m3 to 578.23 kg/m3 respectively. In the case of friability and durability results were found with values ranging from 0.89 to 0.99 and 92.29% to 98.33% respectively values that meet the requirements of the standard. It was determined that the physical properties improved for higher moisture values and lower particle size. In addition, the material used was characterized by finding high contents of sulfur, chlorine and nitrogen in the pineapple stubble that are above that recommended in the standard. The coffee pulp fulfilled all the established in the standard and presented values of lignin superior to the pineapple stubble benefiting the process of pelletizing.

Abstract:
Gyeongbuk provincial government, Korea needs to establish a regional energy plan in 2015 for the next 5 years from 2015 until 2019. It accords to the national basic energy law that every regional provincial government in Korea should implement its regional energy plan every 5-year for the promotion of local economy and sustainable development. Gyeongbuk provincial government has to re-establish a 5-year regional energy plan for the promotion of a specialized regional mid-term energy plan in Gyeongbuk province for coping with the rapid change of energy environment and climate change. In this research, we make a short-list of 7 specialized strategic energy projects by the survey of experts and consideration of its regional environment. We make a prioritization of 7 specialized strategic energy projects by using multi-criteria decision making approach. 2-tier hierarchy is built and it is composed of criteria accounting for local characteristics, market and government policy. Local characteristics consist of local energy demand, timeliness of starting new energy project and possibility of role model in other regional energy plans. In case of market, it accounts for possibility of new regional energy industry creation and job creation possibility. Government policy is composed of national policy adherence, strengthening the capacity of local industry for the climate change and easy to acquire local energy technology. We execute the survey of experts before we prioritize the short-listed energy projects. The analytic hierarchy process which uses 9-points scale is employed for assessing and prioritizing the short-listed of 7 specialized strategic energy projects by making pairwise comparisons of criteria, alternatives and consistency ratio check. The results of this research will provide regional decision makers and regional government officers with the critical decision making data when they focus on the execution of proper regional energy projects considering regional energy environment and limited regional resources including R&D and dissemination of energy related funds.

Abstract:
Global energy environment has been changing due to major issues including climate change, sustainable development and green growth. The advanced economies the U.S, Japan and Germany implemented a strategic R&D and dissemination of new and renewables for leading future energy markets since the early 2000. Specifically, Korean government fast follower, has focused on enhancing a strategic energy technology development with limited R&D budget even though the ratio of R&D budget over GDP is the highest status comparing with other countries. In case of Korea, the strategic energy technology development is equivalent to substitute the effect of natural resource reduction because 97% of the consumed energy in Korea is imported from overseas. Korean economic status is easily affected by the fluctuation of oil price changes due to her poor natural resource status. Now it has been increasing the interest of developing and disseminating new and renewables for sustainable development and low carbon green growth of social system. In this research, we focus on analyzing the relative competiveness of patent status in case of 3 major new and renewables accounting for PV, FC and wind power. This research narrowed down short-list of government sponsored research institutes (GSRI) and major research oriented universities. Patent indicator is one of key factors as decision makers and policy makers for implementing a strategic energy technology development plan and portfolio management for leading the current and future energy technology market during short-/mid-/long-term period. GSRI and major universities have tried to produce R&D outcomes instead of quantitative outputs supported by government and private R&D funds. Decision makers and policy makers of GSRI have been enhancing R&D productivity toward reaching world-class research institutes from qualitative and quantitative aspects. This research carried out for analyzing the relative quantitative competitive analysis of GSRI and major universities in Korea related to 3 major new and renewables for recent 5 years from 2008 to 2013. This research carried out the quantity of registered domestic and international patents related to 3 major new and renewable energy technologies. The research results will provide the fundamental decision making data for energy policy makers when the future R&D strategy in energy technology R&D sector is needed to implement considering the relative status of GSRI.

Title: Impact of foliar application of ascorbic acid on corn (Zea mays L.) under saline conditions
Biography:
Zahoor Ahmad Sajid has research experience in the field of Plant Tissue Culture/Plant Stress Physiology/Biochemistry. His overall research focus is on to study the mechanism of salinity tolerance in agricultural crop and true halophytes (Thellungiella halophila,). Currently, he is evaluating the potential of different biomolecules (salicylic acid, ascorbic acid, proline, KH2PO4 etc.) against various stresses in different agronomically important crops (potato, pea, maize, etc.). Exogenous application of these biomolecules (pretreatment to plants/callus cultures before inoculation/added in medium) or foliar spray to pot-grown plants has shown to have reduced its effect substantially in plants. These biomolecules minimized the oxidative damage by increasing the amount of antioxidant enzymes (superoxide dismutase, catalase and peroxidase) that in turn reflected in better growth parameters of plants.
Abstract:
The aim of this study was to investigate the morphological and biochemical attributes of maize (Zea mays) grown under saline conditions and by exogenous application of ascorbic acid. The experiment was carried out in petri-dishes and pots with randomize complete block design having five replicates for each salt and AA treatment. The certified seeds were sown in petri-dishes with saline water (120 mM) and different concentrations of AA (0, 0.1, 0.5, 1.0 mM). The maize seeds were planted in pots and irrigated with tap water. After that the seedlings were irrigated with saline water of 120 mM while respective concentration of AA was applied foliarly until the plants were harvested after sixty days of salt and AA treatment. Various growth and biochemical parameters were found to be severely affected by saline. These were found to be improved gradually with the increasing concentrations of AA. It is evident from the results of present study that presoaking of seeds with salt (120 mM) reduced the germination percentage significantly up to 60.32% while it was 97.8% under control conditions. The % germination was found to be enhanced from 60.32 (at 120 mM NaCl) to 74.68 at 0.1mM, 81.49 at 0.5mM and 86.76% at 1.0 mM concentrations of AA. AA pretreatment confer salt resistance and is likely to prepare the plants for forthcoming oxidative stress by increasing POD and SOD activity and proline contents at the expense of protein degradation

Title: Reuse of basic oxygen furnace (BOF) slag: Mitigation of high alkaline leachate generation from BOF slag
Biography:
Seulki Jeong is working for Korea Basic Science Institute in Korea. She has her expertise in Environmental Remediation and Management. She is mainly interested in microbial-enhance remediation for contaminated soil with heavy metals such as Cd and As and its risk assessment. Currently, she also does research on environmental management using industrial wastes such as slags. Her research development of stabilization/solidification of heavy metals with steel slags and integrated environmental risk assessment is supporting by the National Research Foundation of Korea (NRF) grant funded by the Korea government.
Abstract:
Basic oxygen furnace (BOF) slag industrial waste from steel-making is generated by 7-9 million tons each year in Korea. BOF slag is reused as construction materials (e.g., land banking and road base). When BOF slags have contact with water however, BOF slag generates highly alkaline leachate (pH>12) by dissolved CaO located on the slags surface. This highly alkaline leachate adversely affects the surrounding environment thus, BOF slag should be appropriately treated prior to reuse. This study aims to mitigate alkaline leachate generation from BOS slag focusing on prevention of CaO dissolution through carbonation. A carbonation test was conducted where BOF slag and NaHCO3 solutions (0.05, 0.1, 0.5, 1.0 M) were agitated with the ratio of 1:5 (g-slag: mL-solution) for 48 hr. The pH and Ca2+ concentration was measured for the leachate. Residual free CaO was measured and x-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) were conducted for the treated BOF slags. No significant difference of free CaO concentration was detected after carbonation indicating that NaHCO3 treatment did not significantly affect reduce free CaO concentrations in BOF slags. However, the leachate pH of BOF slags slightly reduced from 12.0 to 11.3 at 1 M NaHCO3 concentration. TGA and XPS analysis also confirmed that CaCO3 was precipitated on the BOF slag surface after carbonation, preventing additional free CaO dissolution. The results suggested that produced CaCO3 was precipitated on BOF slag forming a coating layer on the surface of BOF slag. The further decrease in leachate pH of BOF slag treated with CO2 gas was obtained (from 12.0 to 10.3). CO2 gas treating solution (pH 7.2) which led to leaching out more Ca2+ than NaHCO3 did subsequently producing more CaCO3 coating on the BOF slags. This finding is expected to contribute to developing appropriate treatments for safe and proper BOF slag reuse.

Abstract:
The MICROALBAC project aims to integrate the cultivation of microalgae in conventional wastewater treatment plants to reduce the energy costs of the systems of oxygenation and agitation of the aerobic reactors as well as the revaluation of the "algal biomass" micro-algae/bacteria through its use as a fertilizer and production of biogas as co-substrate. The effect of the "algal biomass" on plant yield (ryegrass and barley) and soil properties has been evaluated at microcosmos level in comparison with conventional sewage sludge. Five different doses of each organic material have been assayed in quadruplicate. Plants have been grown for two months in a growth chamber and then the aerial part of the plant has been cut and fresh and dry weight as well as nutrients and heavy metal plant content have been determined. Different physical (water holding capacity) chemical (pH, EC, nutrients, heavy metals...) and microbiological parameters (basal respiration dehydrogenase and hydrolase activities) were determined in soils. The effect of this "algal biomass" on lettuce growth has also been evaluated in greenhouse conditions in comparison with the addition of anaerobic sludge and conventional inorganic fertilization

Title: Waste classification of chemicals released from chemical accidents
Biography:
Ha-Yeong Kim received BE degree in Civil and Environmental Engineering from University of Ulsan in 2016. From 2016, she joined the Air Environment and Energy Research Lab in Environmental Engineering from University of Ulsan as Master’s student. Her research area focuses on photocatalytic, water splitting, CO2
conversion and toxic chemical release to environment. She is the Team Leader of project development of judgment and treatment standards for polluted wastes and selection of intensive management target substances.
Abstract:
A significant amount of chemicals are released from various chemical accidents including leaking, explosion, handlings and transports. The released chemical substances or wastes obtained from primary treatments can include hazardous or toxic chemicals which bring difficulty in finding proper disposal. It is because there are no specific guidelines to deal with them. Thus most of the chemicals or wastes obtained from chemical accident treatments have been disposed of as hazardous or designated wastes which require a lot of costs. This study presents a proposed classification procedure or method for chemicals or chemical wastes produced from primary treatments after chemical accidents or releases. This study tries to propose a quantified method to classify chemical wastes by assigning some scores based on NFPA rating, pH rating and waste generation amount. This study rated chemical substances according to the US-based National Fire Protection Association (NFPA) rating systems which arebased on the degree of health risk (blue diamond), Flammability (red diamond), reactivity (yellow diamond), on a scale of 0 to 4 and unusual water reactivity (W) or oxidative capability (oxy) of chemical substances. The pH rating systems of interest acidic or basic chemical substances or wastes were referred by Korean regulations of the designated waste classification and their H+or OH- strength. The chemical substance or waste quantities to be disposed of or treated per day were also considered for the classification by referring Korean regulations of the small amount standard for hazardous chemical substances which should be reported to local or governmental environmental agency. Then chemical substances or wastes are classified as designated or general wastes relying on the integrated scores or score points obtained based on the proposed classification method or procedure.

Biography:
Woori Cho is a Doctorate Course Student of Environmental Engineering at the University of Seoul in Korea. She is a Researcher in the Geo-environmental and Hazardous Waste Laboratory. She has done research organic waste disposal with hydrothermal carbonization to find adequate treatment conditions. Currently, she participates in a project for development of system for integrated management of soil and ground water.
Abstract:
The rapid industrial development is facing problems due to the energy depletion in Korea. Therefore, it is necessary to develop alternative energy sources. Alternative energies like bio-fuels can be produced using waste fuels, so it is ecofriendly. Since the organic waste has been banned to dump in landfill and ocean, one of the most practical methods currently used to reduce organic waste is composting or feed stuffing. Converting organic wastes into useful energy sources may contribute to protecting environment as well as developing alternative energy sources. In this study, bio-char was made from food waste to solve the problems of energy shortage. Bio-char is one of the solid sources in energy production by using organic waste. In this study, it was produced by hydrothermal carbonization (HTC). HTC is a new technology for treating wet biomass waste with a thermal conversion process at relatively low temperature (180-2500C). So, it seems to be a suitable treatment method for Korean food wastes because Korean food waste has a large amount of moisture content and sodium concentration. In this study, biochar is produced by 10 kg of food waste. The reaction degrees are 180, 200, 2200C and the reaction time is for 4, 6, 8 hours, respectively.

Biography:
Olumide Jepson Adedapo holds a Doctor of Philosophy degree in Geology: geothermic based from Ahmadu Bello University, Zaria Kaduna State, Nigeria. He is the Dean at School of Engineering, Federal Polytechnic and Ado-Ekiti Ekiti State. Nigeria. He has many publications to his credit in learned journals.
Abstract:
In this work geothermal energy resources map of the Niger Delta Basin was constructed using borehole thermal log data from about 600 deep wells covering. The Niger Delta areas of interest including offshore for the purpose of locating geothermal reservoirs and estimate their potentials in the basin. Three major thermal reservoir anomalies fields were delineated and quantitatively interpreted as presented in form of maps showing the reservoirs potential areas in both onshore and offshore parts of the Niger Delta. The constructed Niger Delta Maps of geothermal energy resources stored in the sedimentary rock mass for the accessible depth interval 0-4000 m shows two major onshore anomalies, one in the north (with maximum energy values, 800 GJ/m2), another in the east to northeastern part (maximum energy values, 1250 – 1500 GJ/m2). Another two major anomalies are found located offshore, one in the south with values, 750-1000 GJ/m2 occurring at about 100 km seawards and the other, in the southwest offshore with values 750-1250 GJ/m2, still at about 100 km from the shore. A second map of the Niger Delta showing geothermal energy resources stored in the sedimentary rock mass to depth from surface to basement is constructed. In this map, the sedimentary rock thickness is taken to depth of 6.5km. The map shows a small anomaly in the northern part with maximum value 1500 GJ/m2 and a major anomaly occurring in the eastern part of the basin with values 2000-3500 GJ/m2 onshore. Offshore in the south and southwest anomalies in the total sedimentary rock mass occur with highest values, up to 4000GJ/m2 with the southwestern anomaly extending west to the shore. It is much of interest to note the seaward – westward extension of these anomalies both in size, configuration and magnitude for the geothermal energy in the total sedimentary thickness to the underlying basement. These anomalies fields show the most favourable locations and areas of geothermal energy resources for further work.

Abstract:
Simple sugars play vital role in biological functions in living cells. The three commonly known monosaccharides glucose, galactose and fructose used as energy source by organisms. Glucose, exclusively brain fuel has to be regulated in human body to prevent our brain from any potential fuel shortage. Significant drop in blood sugar level can cause lack of concentration, dizziness and headache. Due to this reason it is very critical to develop a chemical sensor that is cheap, simple to use, rapid and efficient to measure and monitor blood glucose level. Supramolecular cyclodextrin polymeric gel is synthesized for the separation of monosacchrides in aqueous solution. A nanometric hollow molecule i.e. cyclodextrin is polymerized by using polymerizing agent and form inclusion complexation with naphthalene probe. Boronic acid is used as sugar recognition terminal, naphthalene as reporter site and alkyl chain as a tail to maximize inclusion complexation. The adsorption phenomenon was investigated by using HPLC, UV-VIS spectrometer and Fluorescence spectrometer. The equilibrium adsorption isotherm was analyzed by using Langmuir modeling. Boronic Naphthalene (B-Nap-Cn) probe was synthesized for selective binding by reacting with cis-1,2-diol and cis-1,3-diols to form reversible covalent complexes. Probes with alkyl chain length of C-4, C-8 and C-12 were synthesized to analyze chain length effect. Results showed that fructose and glucose showed high amount of adsorption towards B-Nap-C4/β-CyD gels and increase in alkyl chain resulted decrease in amount of adsorption for glucose, fructose and galactose. In B-Nap-C4/γ-CyD gel adsorption analysis all three sugars had showed increase in adsorption amount with increasing concentration. This is probably the larger cavity γ-CD could enable probes to freely adjust their active side to bind the sugar. In Summary, B-Nap-Cn incorporated supramolecular cyclodextrin polymeric gel is promising chemical sensor that can be utilized to examine blood sugar level.
