  1. 1. Assessment of trace element stabilization in soil

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

    Sammanfattning : The thesis deals with the remediation of trace element contaminated soil by the chemical stabilization technique. The objective is to complement the knowledge about possibilities of applying the stabilization either (1) as an alternate soil remediation method to excavation and landfilling or (2) for a pre-treatment of contaminated soil before landfilling.

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

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

    Sammanfattning : 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. LÄS MER

  3. 3. Peat Coated with Iron Oxides : Purification of Metal(loid)-Contaminated Water and Treatment of the Spent Adsorbent

    Författare :Alfreda Kasiuliene; Jurate Kumpiene; Ivan Carabante; Prosun Bhattacharya; Luke Beesly; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron-peat; adsorption; arsenic; metals; combustion; hydrothermal carbonisation; landfilling; Avfallsteknik; Waste Science and Technology;

    Sammanfattning : In Sweden due to the industrial activities, such as wood impregnation, multiple point sources of arsenic (As) contamination in soil and water bodies are scattered over the country. Metals, such as chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), cadmium (Cd) or zinc (Zn) at varying concentrations are usually present as well. LÄS MER

  4. 4. Treatment oriented waste characterization

    Författare :Erik Marklund; Lale Andreas; Anders Lagerkvist; Jurate Kumpiene; Bernd Bilitewski; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Sammanfattning : New types of materials and products are developed every day, and subsequently, new types of wastes. At the same time, new regulations are put forth to protect human health and the ecosystems from the negative impacts of wastes. LÄS MER

  5. 5. The use of air pollution control residues in landfill covers and for soil stabilization

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

    Sammanfattning : About 66% of all heat energy generated in Sweden originates from the incineration of municipal solid waste and biofuels such as wood, cardboard and peat. In addition to heat energy, incinerators generate about 1.7 Mt of ashes each year, of which 500 000 t are air pollution control (APC) residues. LÄS MER
