  1. 16. Predictions of leaching from municipal solid waste (MSW) and measures to improve leachate management at landfills

    Författare :Katarina Kylefors; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Landfill leachate from municipal solid waste (MSW) landfills is a long-term emission problem, which may last for several hundreds of years. The waste management resulting in this type of problem cannot be considered sustainable. LÄS MER

  3. 17. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

    Författare :Henrik Hofgren; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

    Sammanfattning : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. LÄS MER

  4. 18. Spatial and temporal dynamics of nutrients in two agricultural catchments in southeast Sweden

    Författare :Andreas Milver; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HYPE-model; phosphorus; nitrogen; arable land; discharge; water quality modeling; snowmelt; nutrient transport; local information;

    Sammanfattning : Many lakes and coast areas in Sweden and all over the globe suffer from eutrophication, caused by an overload of phosphorus (P) and nitrogen (N). In Sweden these emissions from point sources, e.g. LÄS MER

  5. 19. Sustainable Aluminum and Iron Production

    Författare :Reza Beheshti; Emma Strömberg; Jafar Safarian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Optimization; Black Dross; Salt removal; Steel flux agent; Waste processing; Greenhouse gases; Direct reduction; COMSOL Multiphysics®; Kemi; Chemistry;

    Sammanfattning : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. LÄS MER

  7. 20. Development of a process model for a Peirce-Smith converter

    Författare :Andreas Lennartsson; Eetu-Pekka Heikkinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Copper was one of the first metals ever extracted and used by mankind. It is used for its unique properties, like corrosion resistance, good workability, high thermal conductivity and attractive appearance. New mines are opened to maintain a supply of primary feedstock to copper smelters. LÄS MER
