Abstract:
The presentation will report on this Network which brings together waste/biomaterials scientists, industry, city government, and artists to address challenges to waste management. Waste is a significant problem facing an urbanising world, with challenges from waste prevention, treatment/management, to recycling and reuse, and the health impacts of poorly managed waste. In Europe waste production amounts to over 2.5 billion tonnes, but only a limited share (36%) is recycled, with the rest landfilled or burned. Of the 600m tonnes of products and materials that enter the UK each year, only 115m is recycled - 60% of all waste generated in London is currently exported for treatment or disposal outside of the area. This is contrary to the UK Government’s Waste Strategy, requiring waste to be managed as close as possible to the point of production. The total volume of waste generated globally is expected to increase by 50% over the next decade, however there are major variations in landfill disposal - Copenhagen(2%), Paris(11%) to New York(64%). As a recent UK government report stated: we need to make more efficient use of the increasingly valuable resources available to us…where less waste is created, delivering real financial, environmental and social benefits. We need to develop the concept of a circular economy, where one person’s waste becomes another’s valuable resource…Making the changes requires innovation and creative thinking. This also stresses the importance of community/stakeholder-led approaches which the Network is developing through citizen’s science projects such as anaerobic digesters, construction materials re-use and creative recycling schemes.

Abstract:
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. 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 use from the Bugey nuclear power plant (35km away from Lyon) to provide district heating or cooling for the Lyon region in France. It is based on a new heat transportation concept over long distances. This transportation could save a large amount of fossil fuels consumption and reduce greenhouse gases emission that could be particularly harmful in densely populated areas

Gerd Kaupp
University of Oldenburg, Germany
Keynote: How are wastes entirely avoided in solid-state productions?
Time : 10:00-10:30
Biography:
Gerd Kaupp has completed his PhD at the age of 24 years from Würzburg University and postdoctoral studies from Iowa State, Lausanne, and Freiburg University. He held a full-professorship till 2005 in Oldenburg, Germany, and he privately continues his research on wasteless solid-state chemistry (since 1984), AFM on rough surfaces (since 1988), the non-stochastic but versatile and better resolving sub-diffraction-limit microscopy for unstained non-fluorescing materials of all types (resolution <10 nm, since 1995), and (nano)indentations (since 2000). He has published more than 300 papers in renowned journals and has been serving as an editorial board member of several scientific journals.
Abstract:
The top "waste management" requires entire avoidance of wastes in chemical manufacture. Thus, processes must run to completion giving pure products not requiring solvents for removal of excess reagents, unwanted side products, or catalysts by solvents for chromatography. Solid-solid and gas-solid syntheses (since 1984) are the techniques of choice, which upon proper milling can be scaled. For example, horizontal Simoloyer® ball-mills from 1 to 900 liters size are suitable and contain all technical requirements for waste-free industrial production. Lab-scale syntheses are preferably tested in double-walled ball-mills with temperature control at the 100 − 200 mg scale. Since the solids shall not melt during milling the suitable temperature below the eutectic one can be found by cooling or (if necessary) by heating (−78 to +120°C). Cooling and avoiding catalysts profits from activation energy decrease in solid-state reactions (including frozen liquids). This advantage is lost upon melting above the eutectic temperature leaving reactions incomplete and unspecific. Virtually all reaction types (also multi-cascade ones) across chemistry with reactive molecular solids, salts, ductile metals, and gases have been waste-free realized, and numerous scaled to 200 g batches, and some of industrial interest scaled to auto-batches (e.g. manufacture of Al + CNT) or continuous technical manufacture. The temperature control and the product-collection is essential and will be discussed in detail. Transfer of milling impact energy to the reacting system is only necessary for direct mechanical breakage of sigma bonds. The Simoloyer® ball-mills are also suitable for true mechanochemistry and for comminution when recycling by leaching.

Session Introduction
Patricia I Dolez
CTT Group, Canada
Title: Performance of virgin and recycled natural fibers for technical nonwoven applications
Time : 10:30-10:50
Biography:
Patricia Dolez is a researcher at CTT Group in St-Hyacinthe, Quebec, Canada. She holds an Engineering Degree in Materials Science and a PhD in Physics. She has expertise in materials science, textiles, polymers, and composites, and has authored more than 80 papers in refereed journals and conference proceedings as well as several book chapters. She is the Editor of a book “Nanoengineering: Global Approaches to Health & Safety Issues” published in 2015 by Elsevier. She is especially interested in the application of smart textiles, nanotechnologies, natural fibres, and recycled materials in geosynthetics, building materials, and protective clothing.
Abstract:
Natural fibers are generating an increasing interest for various technical nonwoven applications. Indeed, they represent an easily available, low cost, low weight, and environmentally friendly alternative to synthetic materials. Some of them are also available in large quantities as recycled materials, which further reduces the cost. However, most technical applications require well defined properties. This paper presents the results of a comparative study of the physical, thermal and mechanical properties of a list of virgin and recycled natural fibers: Flax, hemp, jute, kenaf, and sisal. Diameters between 40 and 150 µm were measured depending on the fiber type and origin. Fiber length ranged from 50 mm for recycled jute to 200 mm for recycled sisal. With one exception, more than 80% of the fibers were longer than 40 mm, the criterion for nonwoven processing by needle punching. A lower than 350°C degradation temperature was recorded with one source of recycled jute, which may be attributed to the presence of contaminants resulting from its previous use. Finally, the highest breaking force values were recorded for virgin hemp and recycled sisal while the largest elongation at break was obtained for virgin sisal. These results provide some useful information that can be used as a guide for the selection of natural fibers based on the technical requirements of the application. They also show that recycled fibers may be an interesting alternative as long as there is no contamination resulting from their former use.

Title: Extending the life cycle – Novel wood-plastic composites as potential applications for post-consumer wood and plastics
Time : 10:50-11:10
Biography:
Andreas Krause has completed his PhD at the age of 32 years from Georg-August-University Göttingen. He is the Professor for wood composites and processing technology at University Hamburg. He has published more than 50 papers in reputed journals.
Abstract:
Plastics from packaging are of major important in residual waste, which are either energetical recovered or landfilled. Only a small amount is recycled to secondary materials due to the high efforts for sorting and a lack in market of value added products for the recycled plastics. In the first decade of the 21st century, rising prices of crude oil has led to rising prices of plastic from hydrocarbon sources which has in turn affected the demand and rising prices for wooden fuel. In Germany, about 50% of the harvested wood is directly used as a renewable energy carrier. Studies estimated, that in the next 15 years wooden resources will become scarce in Europe due its heterogenous usability as an energy carrier, as a durable building product and as a precursor for the chemical industry by promoting wood as the sustainable key resource in the European Bioeconomy Strategy. Innovation in biomaterials has led to an increasing demand for wood-plastic composites (WPC), which combine the technical advantages of wood and thermoplastics by miniziming the disadvantages of the neat resources. Rescent developments of new thermoplastic biobased recyced materials will be shown. Using secondary resources for WPC exhibited equal stiffness, strength and physical performance compared to virgin resources, what is also beneficial from an ecological point of view by applying the product LCA methodology. An environmental basket of products study assessed the preferable end-of-life alternative of WPC. Recycling of post-consumer WPC tend to be the preferable alternative. Up to now, the least preferable options, incineration and landfilling, are the dominant disposal routes.

Title: Ionic liquids as effective carriers of precious metal ions in membrane processes from leach liquors of metal waste
Time : 11:25-11:45
Biography:
Beata Pospiech has completed her PhD in 2005 at Czestochowa University of Technology, where she works in Department of Chemistry. Her research is focused on the hydrometallurgical methods of non-ferrous metals recovery, especially on the separation of metal ions from aqueous solutions by solvent extraction and transport across polymer inclusion membranes (PIM) containing various compounds as ion carriers. She is a member of European Membrane Society (EMS). She has published more than 20 papers in reputed journals from Journal Citation Reports (JCR).
Abstract:
Many secondary sources contain very often valuable metals. Spent catalysts and industrial wastes can be source of platinum group metals (PGMs). In hydrometallurgical technologies, we obtain acidic solutions after leaching of the metal wastes by inorganic acids. This solution contains usually mixture of different metal ions which should be separated. This separation stage is necessary in the hydrometallurgical process because make possible to obtain clean products in the next stages, such as electrolysis, crystallization, etc. In this work, the transport of palladium(II) from acidic chloride solutions across polymer inclusion membranes (PIM) with phosphonium ionic liquid as ion carrier was studied. Transport through PIM is separation technique of metal ions from aqueous solutions. Effect of the membrane composition on the palladium(II) recovery has been studied. Phosphonium ionic liquids are very interesting group of the ionic liquids (ILs). Their structure and physicochemical properties caused that these compounds are recognized as the promising ion carriers of metal ions from aqueous solutions. The ion carriers are used for the synthesis of polymer inclusion membranes, which also contain polymer matrix (i.e. cellulose triacetate, CTA) and plasticizer (i.e. nitrophenyl alkyl ether). Effective and selective transport of metal ions from the aqueous source phase containing different metal ions into receiving phase depends strongly on the kind and concentration of ion carrier in membrane. Evaluation of the conditions of palladium(II) facilitated transport from hydrochloric acid solutions can be very useful in recycling process of the spent catalysts.

They are currently conducting recent research on recycling of dusts evolved from different Egyptian and German steelmaking fields. He has about 35 scientific contributions published as patents, journal papers, and conference articles.
Abstract:
World production of steel is about 1.6 billion tons annually. About one third of this amount is produced in electric arc furnace (EAF), which evolves about 20 kg of dust per ton of steel. Thus, more than 10 millions of dust waste is formed annually during steelmaking in EAFs worldwide. Recycling of this dust in iron- or steel-making is hazardous and therefore it is mostly dumped. The dust is rich in Fe and Zn (from galvanized ferrous scraps charged to EAF). It contains also elements such as Pb, Cr, and Cd. These toxic elements led the EAF dust to be categorized as hazardous waste, where they leach in water and pollute groundwater. Such dust waste can be also resulted from other steelmaking processes in cupola furnace and other steel converters. In this contribution, we present our results of recent research on recycling of steelmaking dusts evolved from EAF, cupola furnace, and steel converter through selective dissolution of Zn and Pb in deep eutectic solvents composed of mixtures choline chloride with urea and/or ethylene glycol. About 60% of Zn and 40% of Pb found in EAF dust as complex compounds were selectively dissolved. The resultant electrolyte was then used to electrowin Zn-Pb alloys. Pure Zn, which has a very high economical value, can also be electrowon separately. The residual dust, after its extraction in deep eutectic solvents, with lower Zn and Pb and higher contents of Fe oxides can be recycled in steelmaking processes. Moreover, the lowering Zn and Pb contents make the residual dust to be suggested for in corporation in cement synthesis. This approach was also applied for treating dusts evolved from other steelmaking processes and showed promising results.

Abstract:
Waste electric and electronic equipment (WEEE), also called as electronic waste or e-waste, now is proliferating because of technologic innovation. Printed circuit board, as en essential part of almost all electric and electronic equipment, also is obsoleting sharply as the waste stream of e-waste. Waste printed circuit boards (WPCBs) is attracting more and more attention from the government and researchers because it is hazardous but resource rich. Thus, we should recycle the valuable metals from the the angle of pollution controle. Here, we propose a novel technology, slurry electrolysis, to seperate metals and non-metals first and then to recovery nano-copper using the seperated metals as the raw materials. By this technology, for the first step, metals could be successfully seperated from non-metals as micro-metal-powder with a metal recovery rate up to 98%. Then, the obtained micro-metal-powder, maily copper about 86.6%, were slurry electrolyzed for preparing nano-copper. Experiments showed that the abtained nano-copper was smaller than 80 nm with a purity of about 98% and a yield coefficient of about 98%. This technology provide a new approach to completely seperate metals and non-metals from WPCBs and also a high added value product, nano-copper. Of course, envrionmental issues in this process should be considered for field experiment.

Title: Effects of hydraulic retention time, sewage temperature and effluent recycling on efficiency of up-flow anaerobic filter reactor in treating rural domestic sewage
Time : 12:25-12:45
Biography:
John Leju Celestino Ladu has completed his PhD from Southeast University and currently doing his Post-doctoral studies in Southeast University. He worked as Assistant Professor in University of Juba, College of Natural Resources and Environmental Studies and also as Environmental Consultant in private and government institutions of the Republic of South Sudan. He has published more than 15 papers in reputed journals and has been serving as an editor in several journals.
Abstract:
Population expansion and advances in socio-economic standards of rural communities had lead to serious environmental agitation. This paper assessed the effects of hydraulic retention time (HRT), sewage temperature and effluent recycling on treatment performance of up-flow anaerobic filter (UAF). Two experimental operations were performed; the first experiment was performed for four months with HRTs of 24, 48, 72 and 96 hours, temperature of 23.5°C, 25.4°C, 27.6°C and 29.3°C and with effluent recycling ratios of 1:1, 1:2, and 2:1. The second experimental operations were also conducted for four months with HRTs of 48, 72, 96 and 120 hours; temperatures of 10°C, 13°C, 15°C and 18°C; and no effluent recycling. The first experimental operations revealed removal rates of 67% to 77% for COD, 61% to 66% for TN, and 36% to 51% for TP. In the second experimental operations, the removal rates varied from 30% to 36% for COD, 31% to 35% for TN and 10% to 15% for TP. The average gas production rates were 4.5 L/d and 1.3 L/d for the first and second experimental operations respectively. High rate of gas production in the first operations was due to the applied effluent recycling and high temperature as compared to the second operations with no effluent recycling and low temperature. The best removal rate was obtained for an optimum HRT of 96 hours, temperature of 29.3°C and effluent recycling ratio of 2:1. The results revealed that, the removal efficiency of UAF reactor was directly influenced by HRT, temperature and effluent recycling.

Abstract:
Refractory metals (tungsten, tantalum, rhenium, molybdenum and niobium) are highly strategic metals today mainly imported from a few countries. However, resources exist in Europe, as primary resources but mainly as secondary resources through recycling. Valorizing these resourcesrequires coordination and networking between researchers, entrepreneurs and public authorities to harmonise technologies, processes and services, develop standards, create new potential for export of eco-innovative solutions and for seizing newmarkets. By creating a multi-stakeholder platform that draws the currentrefractory metals value chains and identifies its innovation potential, MSP-REFRAM supports the implementation of the European Innovation Partnership on RawMaterials. Coming from industry, research, public sectors and civil society, both Consortium Members and External Expertshave joined forces with expertise covering the whole value chain including mining, processing, recycling, application.The outputs of MSP-REFRAM will help Europe improve the supply value chain of refractory metals in the coming years,optimising the use of external resources as energy and water and at the same time reducing the amount and the toxicity ofwaste.MSP-REFRAM will share its conclusions widely and efficiently, in a long lasting way thanks to the support of the PROMETIAassociation. To ensure the systemic change, the outcomes of the project will be made available to the stakeholders and tothe public through different tools and reports.This paper presents the organisation of the project as well as the first results obtained after the first technical workhsop.

Abstract:
Recently, reduction and recycling of food waste is emerging as an important environmental issue worldwide. Due to the improved living standards and heightened environmental awareness of people, the demand for food waste management system has been increased. In this study, we developed the zero food waste system (processing capacity: 100 kg/d) which can efficiently treat the food waste via fermentation and extinction with wood bio-chip and finally convert it as compost at 30~40°C for 24 hr. The system is composed of input entrance, inside screen and exhaust pipe, etc., with RFID (Radio Frequency Identification) technology. We tested the performance of zero food waste system for 220 days. As a result, weight reduction of food waste was more than 90% and electricity consumption was 6.2 kWh/d on average. In addition, condition of by-product was good enough to be used as compost (i.e., pH: 7.5~8.5, water content: 30~40%, organic matter content: 80~85%, salinity: 0.4~0.5%, and ATP: 600~700 nmol/L). Therefore, it is expected that the developed system could significantly contribute to the reduction and recycling of food waste.

Abstract:
The thermal recycling of waste plastics such as Tetra Pak is achieved via pyrolysis using a semi-pilot plant scale (≈100g) fluidised bed reactor. Resultant oils are sampled from the condensation streams, and chars are collected from the reactor, pre- and post-gas filters. The organic products are characterised using NMR, GC and GC-MS. Both organic and inorganic materials are analysed by ICP-OES and SEM-EDX in order to characterise the deposition of metals throughout the pyrolysis vapour stream. SEM is used to identify and characterise the different morphologies of materials retrieved from the sand bed reactor. It has been demonstrated that NMR is a useful tool for the rapid characterisation of the paraffin, olefin and aromatic functional group ratios for these potentiall valuable oils. Metal distribution is low amongst the oils, and those traces that are present are consistent with corrosion from the reaction vessel. In the case of laminated aluminium plastics such as Tetra Pak, very pure aluminium is deposited in the sand bed char and metal immobilisation throughout is again consistent with reactor corrosion. Indeed, the level of metal contamination found in the chars is such that they may be considered hazardous materials in terms of land fill disposal.

Title: Food Waste prevention in small businesses, the most preferred strategy among food recovery
Biography:
Leo is completing his Masters degree at the age of 28 years at Darmstadt University of Technology and as a visiting student researcher currently doing research on food waste at University of California at Berkeley. He is the director of sustainability at The Better Bowl, a startup using imperfect produce to provide healthy food on campusses. He is going to publish 2 papers in reputed journals in the area around food waste.
Abstract:
Prevention is the most important and preferred action for dealing with the current quantities of food waste. Most recent, published scientific articles regarding food waste are using less ideal strategies for dealing with food waste, such as composting for the use of biomass. The focus of this paper are small businesses, such as restaurants and catering facilities, and exploring options for a decent implementation of recent food waste prevention initiatives. There are different auditing and accounting tools, which are provided by government and stakeholders in the business sectors. However, these tools are not being used in many cases, and the purpose of this paper is to understand why those are not being utilized and how to implement such tools. The lack of knowledge, the existence of different, but not comparable, solutions, and the increasing demand for research around food waste from the side of food processors are the main reasons for choosing this topic. The data for this paper will be based on a survey addressed to small business owners regarding their behavior around food waste. A trial research week monitoring the amounts of food waste and the reasons of the existence of those will be conducted.

Title: Recycling wastes into copper mining operations: Use of industrial ecology strategies to greening Chilean copper industry
Biography:
L Reyes-Bozo completed his MSc and PhD degrees in Engineering Sciences in 2006 and 2011, respectively, both of them from the Pontificia Universidad Católica de Chile. Since 2008, he has been a Full Professor and Researcher of Engineering Faculty, Universidad Andrés Bello. He is the Director of Engineering Science Department. He has published more than 15 papers in reputed journals. He has worked on programs and projects in the mining field, with emphasis on environmental management. His research interests include: use of industrial ecology strategies and cleaner production concepts; assessment of environment-friendly substances as froth flotation agents; modeling, simulation and process control.
Abstract:
Sawdust was used as cheap sorbent for the remediation of a diesel and oil fuel-contaminated mining soil whereas biosolids and their main components (i.e., humic substances, sugars and proteins) were evaluated as main collector and frothers in froth flotation of copper sulfide ores. The use of these waste materials in copper sulfide ore mining and mineral processing may have a positive impact on the cleaner production of copper from its natural raw sources and may decrease the deleterious effect that mining operations have on the environment. Mixtures of oil fuel contaminated mining soil and sawdust were treated in an aerobic reactor at 50.0% humidity for several days. A significant decrease (over 60.0%) of volatile organic compounds content in these mixtures was obtained after one-month of treatment. The total replacement of the main collector with the same dosage of humic acids (38 g/t) resulted in copper recovery and grade concentrate of 85.9% and 6.7% Cu, respectively. Partial replacement (50%) resulted in a slightly lower copper recovery (89.5%), but a slightly higher grade concentrate (5.9%) as compared to use of xanthate. Biosolids with a high content of fulvic substances also showed similar metallurgical indicators. Biosolids and their components have shown to be potential candidates to partially substitute commercial chemicals used in industrial flotation of copper sulfide ores. This possibility opens up an alternative for greening copper sulfide ore flotation by using more environment-friendly flotation reagents. Then, a conceptual model based on industrial ecology and cleaner production principles is proposed for greening the overall copper sulfide ore processing.

In 2004, he began efforts to understand the recycling problems of post-consumer magnesium and low-grade magnesium. He has published more than 80 papers in reputed journals and has been serving as an Editorial Board Member of Advances in Recycling & Waste Management.
Abstract:
Automobile industry has increased the number of components that are produced from Mg alloy. Moreover, Mg alloy products have been widely utilized in 3C (computer, communication, and consumer electronics) products. Therefore, from the manufacturing to the end of life of the Mg products, a massive amount of low-grade Mg scraps (LGMS) is expected to be produced. In this work, LGMS was recycled to be used as hydrogen generator. Molten LGMS bath at 580C in a semi-solid state was prepared. A metallic net was employed as a catalyst. A hot dipping process was developed by dipping the metallic net into the semi-solid bath to form a solidified LGMS overlayer on the net. The LGMS/metallic net was a hydrogen generator in NaCl aqueous. A new H2-on-demand system, comprising mainly aqueous NaCl and LGMS/metallic net was evaluated by measuring the electrical power by proton exchange membrane fuel cell (PEMFC) (driving a motor fan and illuminating a high-power LED lamp). The galvanic couple (LGMS/Pt-Ti net and LGMS/S.S.) generated hydrogen in an NaCl solution (3.5 wt%). The mean volume of hydrogen generated in 50 min was 33.7±4.3 liters as the metallic net was platinum-coated titanium and 16.1± 7.8 liters was produced as the metallic net was stainless steel. On average, one gram of LGMS yielded approximately one liter of H2. Experimental results concerning the about metallic catalysts reveal that the platinum-coated titanium net and stainless steel net can be reused at least five times with comparable H2 yields.

Title: Desulphurizaion of waste tire pyrolytic oil (TPO) using photodegradation and adsorption techniques
Biography:
SDFDSFGBN B
Abstract:
The nature of tires makes them extremely challenging to recycle due to the available chemically cross-linked polymer and, therefore, they are neither fusible nor soluble and, consequently, cannot be remolded into other shapes without serious degradation. Open dumping of tires pollutes the soil, contaminates underground water and provides ideal breeding grounds for disease carrying vermins. The thermal decomposition of tires by pyrolysis produce char, gases and oil. The composition of oils derived from waste tires has common properties to commercial diesel fuel. The problem associated with the light oil derived from pyrolysis of waste tires is that it has a high sulfur content (>1.0 wt.%) and therefore emits harmful sulfur oxide (SOx) gases to the atmosphere when combusted in diesel engines. Desulphurization of TPO is necessary due to the increasing stringent environmental regulations worldwide. Hydrodesulphurization (HDS) is the commonly practiced technique for the removal of sulfur species in liquid hydrocarbons. However the HDS technique fails in the presence of complex sulfur species such as Dibenzothiopene (DBT) present in TPO. This study aims to investigate the viability of photodegradation (photocatalytic oxidative desulphurization) and adsorptive desulphurization technologies for efficient removal of complex and non-complex sulfur species in TPO. This study focuses on optimizing the cleaning (removal of impurities and asphaltenes) process by varying process parameters; temperature, stirring speed, acid/oil ratio and time. The treated TPO will then be sent for vacuum distillation to attain the desired diesel like fuel. The effect of temperature, pressure and time will be determined for vacuum distillation of both raw TPO and the acid treated oil for comparison purposes. Polycyclic sulfides present in the distilled (diesel like) light oil will be oxidized dominantly to the corresponding sulfoxides and sulfone via a photo-catalyzed system using TiO2 as a catalyst and hydrogen peroxide as an oxidizing agent and finally acetonitrile will be used as an extraction solvent. Adsorptive desulphurization will be used to adsorb traces of sulfurous compounds which remained during photocatalytic desulphurization step. This desulphurization convoy is expected to give high desulphurization efficiency with reasonable oil recovery.

Abstract:
Present study highlights isolation of bio-flocculent producing microbes; Achromobacter sp. TERI-IASST N and Achromobacter xylosoxidans TERI L1, capable of biosorption of multi metals (Pb, Zn, Cd, Ni, and Cu). These microbes were isolated from heavy metal contaminated activated sludge samples collected from petroleum refineries. At optimum process parameters (pH 7.5, 37°C temperature, 1% sucrose as feed stock, 120 h incubation period) bioflocculating activity of ‘TERI L1’ strain enhanced (in presence of sucrose as carbon source) to 83.3%. This activity decreased to 73%, when grown in presence of multi-metals. ‘TERI L1’ could adsorb 90% of multi-metals when grown in presence of 1250 mg L−1Zn, 2 mg L−1Cd, 30 mg L−1 Pb, 200 mg L−1Ni and 90 mg L−1Cu and could adsorb 1100 mg L−1 of Pb, when grown in presence of 1500 ppm lead nitrate. ‘TERI-IASST N’ demonstrated 90% flocculation activity (in absence of heavy metals) at optimum condition; ‘pH 6, temperature 37 oC, C/N ratio 1, 1% sucrose as feed stock, 120 h incubation period). In presence of multimetals, flocculation activity of strain N decreased to 84%. ‘TERI-IASST N’ strain revealed 430 mg L−1 Zn and 30 mg L−1 Pb. Bioflocculant yield efficiency of ‘TERI-IASST N’ and ‘TERI L1’ strains were; 10.5 g/L and 5 g/L, respectively. The bioflocculants were thermostable and retained up to 80% flocculating activity after being heated at 90ºC for 30 minutes, which is attributed to the polysaccharide backbone. LC–MS analysis confirmed the bioflocculants as, carbohydrate hetero-polymers. Nuclear magnetic resonance studies revealed that the bioflocculants were glycoproteins. To the best of our knowledge this is the first study that reports the isolation of A. xylosoxidans strain that has significant potential for bioflocculant production as well as for adsorption of multi-metals. The exopolysaccharide bioflocculants produced by ‘TERI L1’ and ‘TERI-IASST N’ strains have good potential for bioremediation of heavy metal contaminated wastewater.

Abstract:
Rubber recycling or reclaiming is growing worldwide because of increasing raw material costs. In addition, extensive use of rubber articles and their eventual disposal is a major concern for the environment Rubber recycling is the process of recycling rubbers that are no longer suitable for use due to wear or irreparable damages. The product of rubber reclaiming in most cases is a partially devulcanized rubber which can replace partially virgin rubber and can be revulcanized for manufacturing new rubbery articles. In rubber devulcanization, three dimensional rubber networks which is the outcome of vulcanization reactions, are broken. In sulphur vulcanization, the formation of both C–S and S–S bonds takes place, and it is therefore expected that during devulcanization, only C–S and S–S bond cleavage should occur. Several techniques were used for rubber devulcanization. They are, chemical, thermo chemical, mechanical, irradiation and biological processes. Irradiation process may include microwave irradiation. The three dimensional rubber network can be broken down by microwave. The energies required to break monosulfidic C-S, polysulfidic S-S and peroxide C-C bonds are 270, 240 and 345 kJ/mol, respectively. Hence, enough caution should be considered during microwave irradiation to break, only C_S and S-S bonds during devulcanization. In this study the microwave devulcanization of three famous waste rubbers, namely, butyl rubber (IIR), tire rubbers and ethylene-propylene-diene rubber (EPDM) were studied. The effect of various parameters, i.e., microwave temperature, several devulcanization agents and corresponding values, were estimated on devulcanization efficiency. The potential use of devulcanized waste rubber as a substitution for new virgin rubber, also were evaluated.

Title: The recycling of air pollution control residue into geopolymers via plasma arc technology
Biography:
Peter Keeley is an Engineering Doctorate student at the University of Birmingham under the supervision of Professor Neil Rowson. He is based at Tetronics International in Swindon, UK where he is working on developing high value products from thermal plasma processing of waste materials. He obtained a Masters of Engineering at the University of Birmingham in 2013.
Abstract:
Air pollution control residue (APCr) is a major hazardous product produced during incineration processes. The material is produced during the cleaning of the gaseous stream produced during incineration removing hazardous chemicals such as chlorine, lead and zinc before it is emitted to the atmosphere. The increase in incineration activities means that APCr production is currently around 300,000 tonnes per year in the UK alone. Thermal plasma technology can be used to vitrify this material and transform it into a non-hazardous glass suitable for commercial use for example as a low grade aggregate. Due to the vitreous nature of the material, it has been found that this material has latent hydraulic properties and can also undergo alkali activation and so form a geopolymer material which could be used as a cement substitute in concrete applications. The recycling of APCr into a material with a high economic value, such as a cement substitute, offers both economic and environmental benefits for the sustainable treatment of this hazardous waste using thermal plasma technology. The geopolymers produced from this material can achieve compressive strengths of over 70 MPa displaying properties which are competitive to commercially available cements.

Title: Identifying the gap in fluorocarbons treatment from waste electrical and electronic equipment (WEEE) in Southeast Asia
Biography:
Atsushi Santo is a Researcher of DOWA ECO-SYSTEM Co., Ltd., a waste management and recycling company in Japan. He has much practical experience at many site-related to waste incineration, metal recovery and so on. And now, he is doing a policy research of the evaluation on WEEE recycling system as a visiting researcher of Institute for Global Environmental Strategies (IGES). Moreover, he is on Doctoral program of Tohoku University.
Abstract:
This study focuses on fluorocarbons (FCs: CFC/HCFC/HFC) emitted from waste electrical and electronic equipment (WEEE) in Southeast Asia. The main measures for FCs under the Montreal protocol as Ozone Depletion Substance (ODS) are restricting the consumption of FCs and converting CFC and HCFC into HFC with zero ODS. However, there is much FCs which still have big environmental impact in operating equipment and HFCs which are not controlled under the protocol has major global warming potential (GWP). The consumption of FCs in Asia has rapidly increased. For example, the demand for air conditioners (AC) in Asia reached 58 million units in 2014. Thus the amount of FCs contained in AC is estimated to be more than 50 thousand tons. The amount could be approximately 100 billion tons-CO2 equivalent. Moreover, there are major differences between countries in regards to regulations for controlling the negative effects of FCs from WEEE. For the appropriate management of FCs, effective WEEE treatment system in which FCs are managed in environmentally sound manner as same as hazardous substance is necessary. According to our survey of FCs treatment, capacity in Southeast Asia is estimated less than 5% of annual consumption and the officially reported amount of destruction of FCs are less than 10t per year. Because of high climate impact, the process of recovery and destruction of FCs should be introduced as early as possible when WEEE treatment systems are going to be introduced with all possible means. For this, international cooperation and relevant technology are essential.

Abstract:
A large quantity of jute fibres is used each year, for example as packaging bags for cotton and coffee or as a building material. These fibres can be recycled after use and given a second life in order to divert them from landfill. However, their performance may be reduced compared to virgin jute. In particular, they may become more sensitive to moisture. Therefore, the aim of this study is to develop a hydrophobic treatment for recycled jute fibres. A non-woven composed of 85% of recycled jute fibres and 15% of sheath/core bicomponent fibres was manufactured by carding/needling and thermally bonded using a calendar. The jute nonwoven was then coated with a dip-pad-dry method using different solutions of titanium dioxide (TiO2) nanoparticles developed by a sol-gel process. It was followed by a treatment by different concentrations of stearic acid, a typical fatty acid. The untreated samples had a water drop retention time of 31s. They became superhydrophilic after being treated with the TiO2 solutions. Upon treatment with more than 4 mM of stearic acid, the sample retention time exceeded 120 min, indicating an hydrophobic behavior. This study also showed that the TiO2 nanoparticles size, which increased with the ethanol concentration in the TiO2 solutions, did not seem to have an effect on the nonwoven hydrophobicity. In addition, no significant effect of the hydrophobic treatment on the thermal stability of the jute nonwovens was observed. This “green” hydrophobic treatment opens large opportunities for technical applications of recycled jute fibres.

Abstract:
The large percentage of Cu present in printed circuit boards (PCBs) residues, usually about ten times more than the Cu amount present in rich-content minerals, makes these residues an attractive secondary source of Cu. The main aim of this work was to develop a simple and nearly-closed two-step process to recover Cu and Al from PCBs residues with high purity. Firstly, a multi-element leaching solution, containing 78 and 85% of the total amount of Cu and Al present in the residue, respectively, together with other metals, was obtained using acidic conditions (HNO3 2M for 210´at 50ºC). The leached solution was constituted by: 66% of Cu and 28% of Al and smaller amounts of Fe, Sn, Zn, Ni and Ag. In a second step, a bispicolylamine resin (Dowex M4195TM) was used to recover Cu with high selectivity. A flow rate of 0.17mL/min/g of resin was applied to allow maximizing Cu recovery (99.5% of Cu retained). Almost no Al, Fe, Sn and Zn were retained. H2SO4 4 mol/L was used as eluent and 96% of Cu was eluated. The use of DOWEXTM M4195 allowed concentrating the Cu in the final solution (from 18mM of Cu to 31mM of Cu) and enabled purifying Cu into a final Cu solution with high grade of purity (99.0%). Additionally, the amount of Al (85%), leached from the residue and present in the raffinate, was totally recovered as a solid of Al(OH)3 with 96% of purity.

Abstract:
Consume of alkaline batteries in the world is increasing and the destination of spent batteries is a concern. Recycling metals from spent batteries could be interesting to decrease the amount of batteries sent to landfill or incineration and for the maintenance of mineral resources. The aim of this work was to recover Zn selectively from spent alkaline batteries using environmental-friendly techniques. Acid leaching was used to extract Zn from spent alkaline batteries. Conventional, microwave- and ultrasound-assisted leaching was tested. Assisted leaching techniques were applied in order to improve: less leaching time and concentration of acid, higher Zn extraction and a higher selectivity of Zn over Mn. Besides Zn, Mn is the major metal present in spent alkaline batteries. For conventional leaching, the best result was 90% of Zn extraction (H2SO4 1.5 mol/L, 3 h, 80ºC). The use of microwave- and ultrasound assisted leaching increased the extraction of Zn for 96% (1 cycle, 30 s, H2SO4 1 mol/L) and 92% (2 min, 0.1p 20% amplitude, H2SO4 1 mol/L), respectively. Assisted leaching techniques allowed recovering a high amount of Zn with a smaller concentration of acid (H2SO4 1 mol/L versus 1.5 mol/L) and much less time (30s and 2 min for microwave and ultrasound versus 3h) than used in conventional leaching. Both approaches showed to be interesting due to the high Zn removal, the low acid concentration needed and the short duration process. However, ultrasounds had better selectivity, resulting in a Zn solution with higher purity grade (83.3%).

Abstract:
The most significant cancer-causing and mutagenic contaminants group of the environment compounds are polycyclic aromatic hydrocarbons (PAHs). The main marker of soil pollution by PAHs is benzo[a]pyrene. Knowledge of soil contamination with benzo[a]pyrene is needed to minimize the risk of human exposure and environmental contamination. The benzo[a]pyrene content in all environmental matrices and food is under obligatory regulations world-wide. The new method for extraction of benzo[a]pyrene – priority industrial pollutant from industrial polluted soil by subcritical water extraction method from soils is the purpose of the research. Studies were conducted on the soils of monitoring plots subjected to Novocherkassk Power Station (NPS) emissions. Monitoring plots were established at different distances from the NPS (1.0–20.0 km). It was shown that the use of water in subcritical state as a solvent for benzo[a]pyrene extraction from soil allows to avoid large volumes of organic solvents and to decrease the time of sample preparation. The method of benzo[a]pyrene subcritical water extraction from soil was developed and approbated during long-term monitoring researches of technogenic polluted territories. The optimum conditions for benzo[a]pyrene extraction from soil have been determined: The soil is treated by subcritical water at 250ºC and 100 atm of pressure for 30 min. Trends in the accumulation of benzo[a]pyrene in soil zones of the thermal power plant influence have been researched over a 4-year period of monitoring observations by subcritical water extraction method. Benzo[a]pyrene accumulation in soils depends on the technogenic emissions to the atmosphere from Novocherkassk Power Station and on the soil physical and chemical properties.

Title: Closing the life cycle of waste fiber reinforced polymer composites by converting it into valuable products
Biography:
Hülya Ucar Sokoli is pursuing her PhD from Aalborg University Esbjerg. She is part of a 2.7 mill Euro Innovation Consortioum (GENVIND), who’s goal is to develop technologies for sustaniable recycling of polymer composites. She is working on chemical degradation of FRP composite waste and is currently the only PhD in Denmark working on this topic.
Abstract:
Polymer composites reinforced with fibers (FRP) are used in almost every type of advanced engineering structure, such as in industrial applications, automobiles, aeronautics, constructions, sports etc. According to the Composite Market Report, the usage of FRP composites exceeded 8.8 million tons in 2014 and continues to grow with a very fast rate. However, despite the successful applications of FRP composites, recycling at the end of the life cycle is associated with major difficulties, due to the cross-linked nature of the thermoset polymer. Therefore, the majority of the FRP composites are currently land-filled or incinerated. These abolition methods are not sustainable in the long term and lead to negative impact on the environment. Chermical degradation of FRP composite waste has shown very promising results. With temperatures in the range of 260-325°C and pressures down to 50 bar, it has been possible to convert the waste into usable end products. This includes: Recovery of expensive monomers with high purity, which can be used to produce new polymers, conversion of the polymer into a potential fuel with high calorific value and recovery of fibers with retained mechanical properties. With these results, the FRP composite end of life cycle can be closed in an environemental and economical beneficial way. Furthermore, some of these achievements have not been attained previously, providing important knowledge in the field of composite recycling.

Abstract:
Energy production from the renewable energy sources is an emerging technology all over the World, especially in the last decades. Biogas production from recycling wastewater is a thriving option to meet the energy demand as well as to prevent environmental pollution. Due to the high content of methane in the biogas, the biogas has a high heating capacity as fuels. This study demonstrates an energy analysis of a gas engine powered by biogas in a wastewater treatment plant (WWTP), located in Turkey. In order to investigate the effect of the biogas on the system performance, the energy efficiency and energy destruction rate for the gas engine are analyzed in the WWTP. The analysis show that the irreversibility occurs in the gas engine is calculated as 2235.66 kW. The second law efficiency of the gas engine is found as 63.12%. As a result, in order to obtain more efficient energy production process, the significant amount of irreversibility occurred in the gas engine must be taken into consideration.

Abstract:
Solid waste management is a very severe deficiency in Kawempe division in Kampala capital city. Most of the parishes in Kawempe division have an unauthorized class of landfills for solid waste disposal. Quite often these landfills are known as garbage pits. These open garbage pits have consequently increased the risks to human health of the people around them because of the exposure of rotting materials, hazardous objects and germs from human excreta such as urine poured in those pits. This has greatly been attributed to by poor policy implementation and weak law enforcers of the existing public health policies to address the deficiency. The division plan for solid waste management has for over time been underperforming due to failure of incorporating the environmental management into the comprehensive development plan of the division, inadequate revenues and adamancy of the general public to be participatory in the campaign for proper solid waste management. Kawempe has an expanded spatial scale with rapid growing economy and population. Informal sector with incoherent activities has increased solid waste without appropriate management. Limited technological alternatives to recycle and onsite treatment are all critically deficient. Therefore for proper solid waste management to be achieved, there is a need to have increased budget for solid waste management as it is in other policy avenues, public participation and strict laws on those that don’t adhere to guidelines. This research has been conducted in Kawempe division to scrutinize and analyze solid waste management procedures, public health policies that have been put in place within the division and its parishes, actions and recommendations made on this that include; Upgrading existing service stations, implementation of strict public health laws, Procurement of materials vital in the collection of garbage with trucks that have GPS tracking systems operationalization of an engineered sanitary landfill in Mpererwe managed by private contractor, increased number of litter bins distributed all over the area to ease the process of solid waste collection. For the objectives’ attainment of this report, features of the waste, rate at which waste is generated, methodology of waste collection, disposal points and roles played by various stakeholders at all management levels were expeditiously researched about and analyzed.
