  3. 22. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE
