1. 6. 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

3. 7. Turning waste into resources: Rethinking the way we discard things

   Sammanfattning : Some of the naturally accumulated biomass and the massive production of waste by human activities have caused serious environmental problems. The degradation of biomass and waste is one of the main greenhouse gasses (GHG) emission sources. LÄS MER

5. 9. Household food waste management – Evaluations of current status and potential improvements using life-cycle assessment methodology

   Författare :Anna Bernstad; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; household waste; food waste; life-cycle assessment; anaerobic digestion; systems analysis;

   Sammanfattning : An increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (SEPA, 2006) and the national environmental objectives state that 35% of all organic household waste should be treated biologically by 2010 (SEPA, 2007).

7. 10. Governing from Above : Solid Waste Management in Nigeria's New Capital City of Abuja

   Författare :Onyanta Adama; Gunilla Andrae; Kristian Stokke; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; governance; space; place; solid waste management; relocated capital city; Abuja; Nigeria; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

   Sammanfattning : This doctoral dissertation examines how the symbolic character of a relocated capital city influences and intersects with local conditions to shape the governance structure and relations in service delivery. The focus is on Abuja, the new capital city of Nigeria, and the sector studied is solid waste management. LÄS MER
