  1. 1. Biochar from separated digestate and pig manure as soil amendment

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Biokolets påverkan på markens organiska material - Kan gödsling med biokol bidra till en kolinlagring i marken?

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Klas Axel Oskar Lucander; [2015]
    Nyckelord :biokol; biochar; kolinlagring; carbon sequestration; carbon storage; SOM; klimatförändring; climate change; avloppsslam; sewage sludge; Earth and Environmental Sciences; Agriculture and Food Sciences;

    Sammanfattning : Here I present a conceptual synthesis of the processes governing soil carbon in the event of biochar application. Biochar is a product of a controlled pyrolysis process and is known for its physical, chemical and adsorptive properties. LÄS MER

    Nyckelord :Energy Efficiency; Carbon Management; Carbon emissions trading; integrated energy and carbon management; energy-related emissions; mineral processing; carbon emissions in mineral processing; energy and carbon auditing; waste heat recovery in mineral processing; waste heat recovery for power generation; flue gas heat recovery;

    Sammanfattning : Copper processing plants involved in smelting, electro-refining and electro-winning are heat-intensive undertakings that provide extensive challenges for attainment of high energy efficiency. Literature has shown that most of these plants, especially smelters, operate at low overall energy efficiency due to the seemingly complex energy scenario where heat and electricity as forms of energy are treated distinctively from each other.
