  3. 2. 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.
