  1. 6. Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population

    University essay from SLU/Department of Molecular Sciences

    Author : Oscar Dolk; [2020]
    Keywords : biogas; anaerobic digestion; ammonia inhibition; acetate enrichment;

    Abstract : This study investigated the problem of ammonia inhibition in biogas reactors, commonly occurring when protein rich substrates are used in anaerobic digestion processes. Ammonia inhibition is one of the foremost causes of failure in anaerobic digestion, leading to process instability, with symptoms commonly expressed as; reduction in biogas produced, decreased methane content in the gas and accumulation of volatile fatty acids.

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  5. 9. Wasted Biogas : Economic analysis of biogas recovery adjoined to existing incineration facility in Sweden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Keywords : Anaerobic Digestion AD ; Residual Waste; Food Waste; Energy Recovery; Biogas Recovery; Incineration; Sweden; Economic Assessment;

    Abstract : Biogas is of growing interest in Sweden, and a public inquiry suggested the government to set a goal of producing 10 TWh biogas in 2030 although only 2 TWh biogas was produced in Sweden in 2018 (Regeringskansliet, 2019) (Klackenberg, 2019). To achieve this optimistic goal and to meet the increased demand of biogas, new biogas production facilities needs to be built. READ MORE

  6. 10. The Potential of Reducing Carbon Footprint Through Improved Sorting

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrika Olsson; [2020]
    Keywords : Waste composition analysis; life cycle analysis; carbon footprint; residual waste; food waste; plastic packaging; Plockanalys; livscykelanalys; klimatavtryck; restavfall; matavfall; plastförpackningar;

    Abstract : Almost five million tonnes of household waste was generated in Sweden in 2018, half of which was residual waste sent for incineration with energy recovery. For materials that can not be recycled or biologically treated, incineration with energy recovery is considered a preferred management option. READ MORE
