2. 1. Systems Aspects of Increased Swedish Waste Incineration

   Author : Jenny Sahlin; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Waste-integrated biorefineries : A path towards efficient utilization of waste

   Author : Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Role of soil organic matter for immobilisation of metals : treatment of leachate from MSWI bottom ashes

   Author : Jurate Kumpiene; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

   Abstract : In this thesis, the focus is laid on the ability of natural organic matter (OM) to serve as a metal stabilising agent. The metal contaminants investigated arise from the MSWI bottom ash leachate. Besides the high content of metals, elevated pH and salinity are characteristic for ash leachate that, in turn, can alter the functionality of OM. READ MORE

6. 4. Mixed fuels composed of household waste and waste wood : Characterization, combustion behaviour and potential emissions

   Author : Mar Edo Giménez; Stina Jansson; Jonas Dahl; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MSW; RDF; persistent organic pollutants; PCDD; PCDF; solid waste pre-treatment; torrefaction; food waste; contaminated wood;

   Abstract :    Incineration with energy recovery is the main disposal strategy for waste that cannot be reused or recycled, and a well-established source of energy in Europe, especially in Sweden where 2.2 Mtonnes of waste including domestic and imported municipal solid waste (MSW) and waste wood (WW) were combusted during 2015.

7. 5. Recovery of copper and zinc in ashes from municipal solid waste combustion

   Author : Jinfeng Tang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyanex 923; MSWI waste; LIX860-I; acidic leaching; waste treatment.; copper; solvent extraction; zinc;

   Abstract : The amount of municipal solid waste incineration (MSWI) fly ash has increased in many parts of the world in recent years. Ashes from municipal solid waste incineration (MSWI) may be a cumbersome waste to handle since containing significant amounts of leachable hazardous metal species and must be landfilled in special sites at high costs.
