  1. 16. Översilningsytors potential att rena lakvatten från PFAS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Larsson; [2020]
    Nyckelord :PFAS; leachate; overland flow area; waste facility; waste; landfill; PFAS; lakvatten; översilningsytor; avfallsanläggning; avfall; deponi;

    Sammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER

  3. 17. Möjligheten att minska metallhalten i lakvatten med sulfatreducerande bakterier

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Sofie Sunesson; [2020]
    Nyckelord :Metals; Landfill; Leachate; SRB; Precipitation; Sulfide; Applied microbiology; Teknisk mikrobiologi; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Anaerobic treatment of landfill leachate using sulphide precipitation was tested at pilot scale for the purpose of heavy metal removal. The emission of leachate is heavily regulated by Swedish authority and the overall concentrations of heavy metals is expected to rise as landfills contain less organic matter. LÄS MER

  4. 18. Using bioaugmentation to enhance the denitrification process in a treatment plant for landfill leachate

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Oscar Skirfors; [2020]
    Nyckelord :Bioaugmentation; Landfill leachate; Wastewater treatment; Biological nitrogen removal; Denitrification; Waste management; Bioaugmentation; Deponilakvatten; Vattenrening; Biologisk kväverening; Denitrification; Avfallshantering;

    Sammanfattning : It has been illegal to deposit household waste in Swedish landfills since 2005. The large amount of waste deposited prior to this does however continue to pose an environmental concern, mainly in the form of leachate water. This study focused on enhancing the denitrification process in a leachate water treatment plant through bioaugmentation. LÄS MER

  5. 19. Developing a SustainableSupply Chain for Waste Management : A Case Study of Lombok

    Kandidat-uppsats, KTH/Industriell produktion

    Författare :Oscar Wiberg; Anton Östblom; [2020]
    Nyckelord :Waste management; sustainable; developing countries; Lombok; Indonesia; supply chain; investment; sustainability; plastic recycling; Avfallshantering; hållbar; hållbarhet; utvecklingsländer; Lombok; Indonesien; distributionskedja; investeringar; plaståtervinning;

    Sammanfattning : Lombok is an island in Indonesia located next to, and slightly smaller than Bali. The tropical island has the potential tobecome “the next Bali” in terms of tourism and is like many other developing countries, suffering from inadequate solid waste management, as of 2020 only managing 20% of its waste.

  7. 20. Markytesänkning, växthusgasavgång och utlakning från dikad torvjord

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Martin Ahlvin; Sofia Alexandersson Ros; [2020]
    Nyckelord :Dikad torvmark; höjdmätning; markytesänkning; koppargödsling; växthusgaser;

    Sammanfattning : Greenhouse gas emissions and land subsidence on four cultivated peat soils (Martebo, Örke, Kälkestad, Lidhult) have been investigated by measuring emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) in field and lab. Greenhouse emitted gas (mg/h) from undisturbed soil cores was measured in lab. LÄS MER
