  2. 1. Interest in Material Cycle Closure? Exploring Evolution of Industry's Responses to High-grade Recycling from an Industrial Ecology Perspective

    Author : Philip Peck; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; polymers; vehicles; ELV; extended producer responsibility; chemical recycling; material cycling; material flows; closed-loop recycling; Industrial Ecology; recycling; aluminium.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Many anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. READ MORE

  4. 2. Waste Textiles Bioprocessing to Ethanol and Biogas

    Author : Azam Jeihanipour; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

  5. 3. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships

    Author : Joao Patricio; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Top-down methods; Industrial Waste; Recycling; Material Inputs; Industrial Symbiosis;

    Abstract : Industries in Europe are responsible for generating approximately 190 Mtons of waste; a figure which is expected to rise, as a significant increase in the consumption of raw materials is predicted to occur in the near future. This may lead to escalating environmental problems, including resource depletion, soil degradation, and climate change. READ MORE

  6. 4. Industrial Ecology Methods within Engagement Processes for Industrial Resource Management

    Author : Graham Aid; Nils Brandt; Maria Malmström; Enell Magnus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Management; Recycling; Stakeholder Participation; Industrial Symbiosis; Construction and Demolition;

    Abstract : The global use of resources such as materials, energy, and water has surpassed sustainable levels by many accounts.  The research presented here was explicitly normative in its aim to improve the understanding of, and make sustainable change toward highly systemic issues of resource management.

  7. 5. Sulphur-Utilizing Microorganisms in Biotechnological Applications - Rubber Recycling and Vanadium Reduction

    Author : Katarina Bredberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrococcus furiosus; Acidithiobacillus; microbial vanadium reduction; microbial detoxification; rubber recycling; devulcanization; Biotechnological desulphurization; waste rubber materials; Biotechnology; Bioteknik;

    Abstract : Biotechnological processes offer environmentally friendly and sometimes cost-effective alternatives to traditional chemical and mechanical methods. It is important to take advantages of the opportunities these processes provide to fulfil the demands and expectations of a future environmentally sustainable society. READ MORE
