  1. 1. 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

  3. 2. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tsai-wei Tang; [2022-01-26]
    Keywords : N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Abstract : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. READ MORE

  4. 3. Biochar from separated digestate and pig manure as soil amendment

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

  5. 4. Development of a Novel Biocatalytic Cascade for the Valorisation of 5-(Hydroxymethyl)furfural

    University essay from KTH/Industriell bioteknologi

    Author : Johannes Johansson; [2022]
    Keywords : Biocatalysis; Enzyme immobilization; 5- Hydroxymethyl furfural; Transaminase; Galactose Oxidase; Biokatalys; Enzym-immobilisering; 5- hydroxymetyl furfural; Transaminas; Galaktosoxidas;

    Abstract : Den nära förestående bristen på fossila resurser i kombination med deras associerade miljöfarlighet betonar behovet av utveckling av alternativa, mer hållbara kemikalier. I denna studie utvecklades en enzymatisk kaskad för förädling av 5-(hydroxymetyl)furfural (HMF) till 5-(aminometyl)-2-furfuraldehyd (AMFA). READ MORE

  6. 5. Organic Electrochemical Transistors for the Detection of Xanthine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yunfan Lin; [2022]
    Keywords : Xanthine; OECT; Biosensor; PIBET-AO; Xanthine Oxidase XOD ; Xantin; OECT; Biosensor; PIBET-AO; Xantinoxidas XOD ;

    Abstract : Food waste is gradually becoming a serious global issue in recent decades. It is reported that more than 1.3 billion tonnes of food consisting of around 50 % meat products are wasted every year on a global scale, while there are more than 800 million of the global population who are starving at the same time.
