2. 1. Designing out waste - Exploring barriers for material recirculation

   Author : Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

   Abstract : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

4. 2. Turning waste into resources: Rethinking the way we discard things

   Author : Maria Isabel Ordonez; Isabel Ordonez Pizarro; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; resource recovery; material loops; waste sorting; user centred design; design with waste; waste collection systems; waste sorting;

   Abstract : Waste is one of the biggest challenges faced by our society. If not handled correctly, waste pollutes our natural environment with devastating results. However, it seems almost unavoidable that our society generates waste. READ MORE

5. 3. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

   Author : Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

   Abstract : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.

   Abstract : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. READ MORE

7. 5. Environmental System Analysis of Waste Management : Experiences from Applications of the ORWARE Model

   Author : Anna Björklund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste MSW ; waste management; waste management planning; model; environmental systems analysis; life cycle assessment LCA ; substance flow analysis SFA ; substance flows; environmental impact; energy; uncertainty; Chemical engineering; Kemiteknik;

   Abstract : Waste management has gone through a history of shiftingproblems, demands, and strategies over the years. In contrastto the long prevailing view that the problem could be solved byhiding or moving it, waste is now viewed as a problem rangingfrom local to global concern, and as being an integral part ofseveral sectors in society.
