    Sammanfattning : Biogas is a renewable energy source produced by decomposing organic matter in the absence of oxygen. Without oxygen, organic matter is broken down in this process, producing a mixture of gases that may be used for a variety of tasks, such as heating, cooking, and producing power. LÄS MER

  7. 5. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER
