  1. 11. Ogräsfrönas överlevnad i biogasanläggningar : en litteraturgenomgång och ansats till metaanalys

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Elin Strömberg; [2023]
    Keywords : anaerobisk nerbrytning; biogas; biogasreaktor; biogödsel; dödlighet; frö; ogräs; retentionstid; rötning; rötrest; rötslam; substrat; temperatur; överlevnad;

    Abstract : Sveriges energibehov 2020 var 508 TWh och av det är kärnkraft, biobränsle, olja och vattenkraft de viktigaste energislagen. På grund av att biogasproduktion har ett netto noll utsläpp har regeringen har valt att investera 40% av klimatklivets budget till dessa projekt. READ MORE

  3. 12. 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

  4. 13. Techno economic assessment of CCUS for a biogas facility in Sweden : Evaluating the economic feasibility for three CCUS concepts

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tobias Johansson; Markus Knutsson; [2022]
    Keywords : CCS; CCU; CCUS; Biogas; Biologic methanation; Negative emissions; TEA; Techno economic assessment.;

    Abstract : Many countries strengthen their commitments to reduce greenhouse gas emissions to limit climate change and meet the Paris Agreement (Masson-Delmotte et al., 2019). Commitments include achieving net-zero emissions or in some cases even negative emissions (Government offices of Sweden, 2020a; United Nations, 2021a). READ MORE

  5. 14. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Malin Lane; [2022]
    Keywords : Gräsvallar; klimatpåverkan; kolinlagring; jordbruk; biomassa; biobränslen.; Earth and Environmental Sciences;

    Abstract : Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. READ MORE

  6. 15. Klimatpåverkan och energianvändning vid tillämpning av bio-CCS och bio-CCU från biogasanläggningar

    University essay from SLU/Dept. of Energy and Technology

    Author : Emelie Wallman; [2022]
    Keywords : livscykelanalys; koldioxid; biometan; power to gas; biologisk metanisering; katalytisk metanisering; elektrolys;

    Abstract : To mitigate the human-induced climate change, Sweden has adopted a climate policy framework that states a net-zero emissions of greenhouse gases by the year of 2045 and thereafter negative emissions. To achieve this goal extensive emission mitigation alongside supplementary measures are required. READ MORE
