1. 1. 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.

3. 2. Systems Aspects of Increased Swedish Waste Incineration

   Författare :Jenny Sahlin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

   Sammanfattning : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. LÄS MER

4. 3. Treatment oriented waste characterization

   Författare :Erik Marklund; Lale Andreas; Anders Lagerkvist; Jurate Kumpiene; Bernd Bilitewski; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

   Sammanfattning : New types of materials and products are developed every day, and subsequently, new types of wastes. At the same time, new regulations are put forth to protect human health and the ecosystems from the negative impacts of wastes. LÄS MER

5. 4. 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

7. 5. Waste incineration residues : Persistent organic pollutants in flue gas and fly ash from waste incineration

   Författare :Eva Weidemann; Lisa Lundin; Stellan Marklund; Jean-Francois Boily; Henrik Bristav; Kees Olie; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSW; PCDD; PCDF; PCN; PCB; POP; formation; degradation; case study; flue gas sampling thermal treatment; fly ash; surface characterization;

   Sammanfattning : Modern societies produce large quantities of municipal solid waste (MSW), which is commonly disposed of by incineration. This has several advantages: it reduces the waste’s volume and sterilizes it while also enabling energy recovery. LÄS MER
