  1. 1. Centering farmer perspectives on a dry-fertiliser made from human urine: a case study on Gotland, Sweden

    Master-uppsats, Lunds universitet/LUCSUS

    Författare :Nicola Parfitt; [2023]
    Nyckelord :circular nutrient economy; human urine fertiliser; ecological sanitation; eutrophication; sustainability science; Social Sciences;

    Sammanfattning : To reduce eutrophication and close the nutrient loop between sanitation and agriculture, innovations to recycle human waste are being further developed. As there is little research on Swedish farmer perspectives towards human urine fertilisers, this study investigates Gotlandic farmer perspectives on a dry-fertiliser derived from human urine, developed by Sanitation360.

  3. 2. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Ellen Ek Moreau; [2023]
    Nyckelord :Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Sammanfattning : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

    Nyckelord :Circular Economy; Green Taxes; Landfill; LRSC; Plastic; SMEs; Waste;

    Sammanfattning : The current global waste problem presents significant challenges worldwide, and Spain is no different. Factors such as rapid urbanization, population growth, intensive agriculture, linear production models, and changing consumption patterns contribute to the upward trend in waste generation. LÄS MER

  5. 4. Extrahera tungmetaller ur rötrest med naturligt anskaffade ämnen

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Linda Watkins; Frida Jönsson; [2023]
    Nyckelord :;

    Sammanfattning : As the demand for biogas increases, so does the amount of digestate produced. Digestate contains large amounts of nutrients and has been introduced in agriculture as an alternative plant nutrient. LÄS MER

  7. 5. An Environmental (LCA) and economic assessment (LCC) of on-farm and centralized alternatives for biogas production for two Swedish farms in Götene

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

    Författare :Abdelali Ouakrim; [2023]
    Nyckelord :Life cycle assessment; LCA; life cycle costing; LCC; biogas; animal manure; biogas production; co-digestion;

    Sammanfattning : Biogas production through anaerobic digestion is an important part towards the achievement of a bio-based and circular economy in Sweden. In fact, Swedish government proposed a strategy suggesting that biogas production should be increased from 2 TWh today to 7 TWh by 2030. LÄS MER
