  1. 26. Durability of Cementitious Materials in Long-Term Contact with Water

    Författare :Arezou Babaahmadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nuclear electricity is considered to be an alternative energy production solution for the power industry in many countries. To ensure the sustainability of this energy solution, the disposal of the produced waste is one of the biggest issues facing nuclear electricity industries. LÄS MER

  3. 27. New insights into solubility control mechanisms and the role of particle- and colloid-facilitated transport of metals in contaminated soils

    Författare :Åsa Löv; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Particle- and colloid-mediated transport of metals can be an important leaching pathway in contaminated soils, making it necessary to include this process in risk assessments of contaminant transport. In this thesis, mechanisms involved in transport of particulate, colloidal and truly dissolved lead, chromium, zinc, arsenic and antimony were studied in an irrigation experiment performed on intact soil columns from four historically contaminated soils.

  4. 28. Assessment of thermal treatment of trace element contaminated soil

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

    Sammanfattning : Many contaminated sites in Sweden are characterised by a complex contamination situation with a mixture of organic and inorganic contaminants. For example, wood preservation with creosote, pentachlorophenol and chromated copper arsenate (CCA) has caused this kind of co-contaminated sites. LÄS MER

  5. 29. Gamma irradiation in multi-cycle ABS recycling- effects on ABS properties and the recovery of antimony

    Författare :Sandra Tostar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ABS; antimony; gamma irradiation; recycling; WEEE; plastics;

    Sammanfattning : Electronic waste, also called waste electrical and electronic equipment (WEEE), is the fastest growing waste stream in Europe today. The fast exchange pace of mobile phones, televisions and computers creates an important need to develop recycling areas to take care of, reuse and recycle these materials. LÄS MER

  7. 30. Resource efficient control of Elymus repens

    Författare :Björn Ringselle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Elymus repens is a perennial grass weed that causes great yield losses in a variety of crops in the southern and northern temperate zones. Primary control methods for E. repens are herbicides or intensive tillage, both of which have a number of negative side-effects, e.g. LÄS MER
