    Sammanfattning : The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. The result shows that  current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem.

  3. 2. Characterization and treatment of municipal landfill leachates

    Författare :Ulrika Welander; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical chemical treatment; biological treatment; characterization; organic substances; leachate treatment; municipal landfill; Biotechnology; Bioteknik;

    Sammanfattning : Abstract The efficiency of different leachate treatment methods for the removal of refractory organic compounds and ammonium-nitrogen was investigated. The methods evaluated were nitrification, denitrification, adsorption onto activated carbon, precipitation by ferric chloride or aluminum sulphate and oxidation by ozone or Fenton´s reagent. LÄS MER

  4. 3. Modern landfill leachates – quality and treatment

    Författare :Hanna Modin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy metals; European Landfill Directive; Biodegradation; Landfill leachate; Leaching tests; Multivariate data analysis; Organic matter; Sorption filters;

    Sammanfattning : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. LÄS MER

  7. 5. Generation of Leachate and the Flow Regime in Landfills

    Författare :David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. LÄS MER
