   Sammanfattning : This thesis examines the use of various osseous raw materials in craft activities in the Mälaren region during the Middle Ages. Places studied are: Birka, Sigtuna, Nyköping, Strängnäs and Uppsala. The aim is to capture both chronological and spatial changes in the use of osseous raw materials. LÄS MER

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

   Författare :Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. 3. The economics of residual waste : policies, price discrimination, and welfare

   Författare :Sef Meens-Eriksson; David Granlund; Runar Brännlund; Thomas Broberg; Raymond Gradus; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste economics; net social cost analysis; waste incineration; municipal waste policy; waste taxes; price discrimination; spatial competition; welfare effects; Economics; nationalekonomi;

   Sammanfattning : Paper [I]: In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs related to energy production, alternative waste management and fuel transport.

7. 5. Waste-integrated biorefineries : A path towards efficient utilization of waste

   Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. LÄS MER
