  1. 1. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johanna Forss; [2023]
    Keywords : etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Abstract : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. READ MORE

  3. 2. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Cassandra Kestran; Olivia Larsson; [2023]
    Keywords : Ammonia stripping; Eutrophication; Fertiliser production; Gas permeable membrane; Haber-Bosch; Nitrogen management; Nitrogen recovery technologies; Nitrogen removal; Reject water;

    Abstract : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. READ MORE

  4. 3. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Gustavsson; [2021]
    Keywords : Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Abstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE

  5. 4. Fertiliser derived from human urine : novel media for alkaline urine dehydration

    University essay from SLU/Dept. of Energy and Technology

    Author : Christopher Friedrich; [2021]
    Keywords : nutrient recovery; fertiliser; urine drying; source separation; magnesium oxide; calcium hydroxide;

    Abstract : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. READ MORE

  6. 5. No-till grain legume production in organic farming : constraints, possibilities and potential agronomic practice

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Zuzanna Chetnik; [2020]
    Keywords : no-till; conservation tillage; cover crops; intercropping; organic farming; grain legumes;

    Abstract : Today’s agriculture is often specialised, and relies on pesticides, synthetic fertiliser and tillage. Tillage, especially ploughing, has shown to have a negative impact on climate, soil health and -biodiversity. An alternative is no-tillage, a practice that leaves the soil almost undisturbed except for minimal impact during sowing. READ MORE
