  1. 1. Biochar as a carbon dioxide removal solution : An assessment of carbon stability and carbon dioxide removal potential in Sweden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Alessandro Corbo; [2020]
    Nyckelord :Climate change mitigation; biomass; pyrolysis; soil;

    Sammanfattning : Biochar is increasingly gaining momentum in the context of climate change mitigation and its production in Sweden could potentially become a large-scale system. Carbon stability in biochar is a crucial factor to assess its the carbon sequestration potential. LÄS MER

  3. 2. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jordy van Osch; [2020]
    Nyckelord :Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

    Sammanfattning : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. LÄS MER

  4. 3. Pharmaceuticals leaching from biosolids amended soils

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Anastasia von Hellens; [2015]
    Nyckelord :biosolids; pharmaceuticals; leaching; soil texture; correlation analysis; physiochemical properties;

    Sammanfattning : Biosolids are currently applied on arable land in order to recirculate nutrients from urban areas. Biosolids have been reported to contain organic con-taminants such as pharmaceuticals; thereby the impact of spreading of bio-solids on the environment has to be investigated. LÄS MER

  5. 4. Optimised ammonia sanitation of sewage sludge

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Franziska Häfner; [2014]
    Nyckelord :ammonia; urea; sanitisation; compost; sewage; sludge; Enterococcus faecalis; Escherichia coli; Salmonella Typhimurium; Ascaris suum; somatic coliphages;

    Sammanfattning : The usage of sewage sludge as an organic fertiliser offers a way to recycle nutrients and organic matter for a sustainable agriculture. Sewage sludge is rich in plant nutrient like nitrogen, phosphorus, potassium and micronutrients. LÄS MER

  7. 5. Metanpotential för alger och bioslam blandat med pappersfiber

    Kandidat-uppsats, Institutionen för bygg- och energiteknik (BE)

    Författare :Lejeby Ebba; [2013]
    Nyckelord :Biogas; metanpotential; rötning; satsvisa försök; mesofil; termofil; Saccharina latissima; Laminaria digitata; bioslam från pappersbruk; Seafarm;

    Sammanfattning : In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas. LÄS MER
