Abstract:

Climate change requires answers beyond the pure optimization of resources consumption and energy demand management in areas like manufacturing. CO2 as a supply for new synthetic raw materials and products as well as markets is a long-term approach to establish a green cycle economy. We define green cycles as CO2 sinks. The Siemens green cycle vision for green production and green raw materials opens new manufacturing models and new product markets to provide an answer for the world’s hunger for materials. These materials have a promising future for non-food related components such as electronic parts. Green cycle factories apply the concept of green cycles to the discrete manufacturing industries. The prerequisites are CO2-neutral forms of renewable energy as well as chemistry production technologies, which are synthesizing fuels and materials for manufacturing from CO2 sources which then yield the recycling of CO2. One economic driver is the merging of different energy grids. The focus lies on renewable supplies that fulfill the demands of future manufacturing technologies in terms of additive manufacturing processes which are mainly using carbon materials coming from renewable, biodegradable resources. The transformation process requires new manufacturing systems in a decentralized and mostly digitalized manner. A new additive manufacturing process based on this carbon feedstock is one promising application field with the advantage to transfer the CO2 load into discrete products. Hence, low carbon in the atmosphere can be realized by green cycles, i.e. CO2 recycling and advanced carbon-based materials and manufacturing.

Abstract:

The reduction of the use of natural resources and the use of a waste material avoiding problematic landfills, have been the principal points to open an important recycling market in most developed countries. Crushed concrete and masonry waste can be suitable for replacing coarse aggregate in concrete. When crushed masonry is used, compressive strength is lower and his high porosity affects durability and shrinkage. With crushed concrete aggregate the compressive strength and durability depend on the quantity of attached mortar. Attached mortar is responsible for higher porosity, weak zones in the aggregate and is related too with the new concrete durability. Smart crushers liberate more adhered mortar and can be a good solution.rnMethods to guaranty the quality of the production of good quality are developed, but inhomogeneity of the concrete waste of different origins continue to inspire distrust in many consumers, that prefer the use as sub base material in roads. Irregularity of the distribution of chlorides or other contaminants makes complicated the quality control, but combined analysis of durability and sustainability and the use of indicators and models can be a solution. The in situ recycling with only one origin of concrete can assure homogeneity.rnMany papers reflect the need of more cement to compensate the differences in properties compared with concrete with primary aggregates.rnWhen studied with LCA we can see that cement is, by far the most influencing factor in terms of CO2 emissions. More cement can prevent the sustainability of recycled concrete. Several solutions will be proposed to make the recycled concrete sustainable, from the combined use of mineral additions and chemical admixtures to new mix design methods that can achieve equal performances in fresh state, strength and durability.

Biography:

F Andreola graduated in Chemical Engineering at the University of Bologna (1992). She completed her PhD in Materials Engineering at the University of Modena and Reggio Emilia (1997). She currently develops her activity at Department of Engineering “Enzo Ferrari” (DIEF) from University of Modena. Her research is mainly focused in the science and technology of materials, and in particular in the study and development of eco-compatible products for building sector (ceramic tiles, bricks, ecological bodies, and glass-ceramics). She is Co-author of 100 papers in international peer-reviewed journals. She has presented her research activity in a large number of national and international congresses. She is a member of the Italian Ceramic Society, Italian Association of Materials Engineering and Italian Group of Clays. She acts as a Reviewer for several peer reviewed journals like J. European Ceramic Society, Ceramic International, Waste Management, and J. of Sustainable Engineering.

Abstract:

The progressive increase in wastes requires not only measures to reduce their generation, but also recycling and reuse. In this regard, the European directives concerning waste, Directives 2006/12/CE and.2008/98/CE, are oriented to transform the European Union into a “recycling society” that attempts to avoid the generation of waste and promotes their use as a resource. Inorganic wastes in Europe are estimated more than 1,500 million tonnes/year and traditionally they have been disposed of in landfills. Alternative ways of reuse or recycling of non-hazardous inorganic waste should be investigated and implemented. On the other hand, traditional ceramic manufacturing requires massive amount of natural raw materials, which until few years were mainly based on the conventional system clay-silica-feldspar. Besides, natural raw materials used show a wide range of compositional variations and the resulting products are very heterogeneous. Therefore, such products can tolerate further compositional fluctuations and raw material changes, allowing different types of wastes to be incorporated into the internal structure of ceramic tiles and bricks as part of their own matrix. Nowadays, ceramic tile cycle works at zero emissions permitting to recycle within own manufacturing process all by-products and partially residues derived from depuration process and wastes coming from other productive cycles. In this review, will be described the state of art regarding the introduction of wastes in ceramic tiles and bricks manufacturing. Case studies of formulations using different percentages of alternative raw materials as waste glass, MSWI bottom ash, agro waste and polishing sludge are reported.

Abstract:

The increase in generation of waste from construction activities along with significant increase in global population has led to increasing focus and research on reuse of waste material. In this keynote presentation, applications of Construction and Demolition (C&D) materials in roads and footpaths based on research currently undertaken in Australia are discussed. Unbound and stabilized C&D materials have been evaluated by the presenter to assess their viability for reuse in pavement bases/subbases. C&D materials including Recycled Concrete Aggregate (RCA), Crushed Brick (CB), Reclaimed Asphalt Pavement (RAP), Fine Recycled Glass (FRG) and Waste Rock (WR) have been evaluated in the laboratory and new specifications successfully developed in Australia to incorporate their usage in pavements, footpaths and other civil engineering applications. In addition, several unique field case studies where C&D materials have been used in roads and footpaths in Australia will also be presented. In addition current ongoing projects on some other traditional waste materials currently being researched by the presenter will be briefly discussed.
