  1. 11. Waste handling at Swedish recycling centres : work environment and risks

    Författare :Rickard Svensson; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The amount of household waste generated in Sweden is increasing. Not many years ago, a majority of this was landfilled. Today, 95% of Swedish household waste is either incinerated with energy recovery, material recycled, or biologically treated. LÄS MER

  3. 12. Hydrometallurgical Treatment of Neodymium Magnet Waste

    Författare :Marino Gergoric; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; recycling; rare-earth elements; leaching; Keywords: neodymium magnets; solvent extraction;

    Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

  4. 13. Performance of landfills of hazardous waste with special respect to the function of clay liners

    Författare :Laith Al-Taie; Rolf Sjöblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : This licentiate thesis is based on four papers related to the performance of near-surface low-level (LLW) repositories (landfills) focusing on construction and performance of clay liners in the cappings. The first paper discusses the source of hazardous wastes, their location and their impact on public health. LÄS MER

  5. 14. Metal retention from leachate using Industrial Waste Products

    Författare :Emma Nehrenheim; Sylvia Waara; Hanna Obarska-Pemplowiak; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Sammanfattning : Landfill leachate arises when water percolates through a landfill. The degree and type of pollution is dependent on the content of the landfill but also on a range of other factors, including the age of the landfill and the landfilling technique. LÄS MER

  7. 15. Metal distribution and mobility under alkaline conditions

    Författare :Mårten Dario; Bert Allard; Yngve Albinsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Adsorption; Colloids; Nuclear waste; Cement; Montmorillonite; miljökemi; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : The adsorption of an element, expressed as its distribution between liquid (aquatic) and solid phases in the biogeosphere, largely determines its mobility and transport properties. This is of fundamental importance in the assessment of the performance of e.g. geologic repositories for hazardous elements like radionuclides. LÄS MER
