2. 1. 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.

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

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

   Abstract : 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).

   Author : Björn Hedman; Stellan Marklund; Calle Nilsson; Brian Gullett; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

   Abstract : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

6. 4. A System Perspective on District Heating and Waste Incineration

   Author : Kristina Holmgren; Björn Karlsson; Anna Björklund; Linköpings universitet; []
   Keywords : Energy recovery; District heating; Waste incineration; Waste management; Environmental; Material recovery; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Energy recovery by waste incineration has a double function as waste treatment method and supplier of electricity and/or heat, thereby linking the systems of energy and waste management. Both systems are undergoing great changes, mainly due to new regulations. READ MORE

7. 5. Low-hanging fruit : Measures to reduce fruit and vegetable waste at supermarkets

   Author : Lisa Mattsson; Helén Williams; Casper Boks; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food waste; retail; supermarket; fruit and vegetable; causes; measures; employees; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : More than 30 percent of the food produced for human consumption is lost or wasted globally. This leads to a significant environmental impact in terms of inefficient use of natural resources, as well as economic costs and social and moral issues. READ MORE
