  1. 1. Profitability of optimizing biogas production in dairy farms : an experimental case study of a Swedish dairy farm´s usage of nitrogen in digestate as a nutrient resource for crop production

    Master-uppsats, SLU/Dept. of Economics

    Författare :Nils Hermansson; Albin Åkerblom; [2023]
    Nyckelord :biogas; optimization; profitability; economic effects; organic; conventional; agriculture; dairy farms; digestate; nitrogen; biogas; optimering; lönsamhet; ekonomiska effekter; ekologiskt; konventionellt; lantbruk; mjölkgårdar; rötrester; kväve;

    Sammanfattning : Biogas has the potential to be a contributor to sustainable energy for electricity, fuel, and heating. Because of that, there are different alternatives for biogas plants. In this study, a farm-based biogas plant for electricity production has been of interest. LÄS MER

  3. 2. Increase of biogas production by incorporating residual streams from agriculture

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Stephanie Fjäll; [2022]
    Nyckelord :Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. LÄS MER

  4. 3. Energipotential för biogas i gödsel från svenska mjölkproducerande lantbruk : Med utgång från en gårdsbaserad biogasanläggning i Kalmar kommun

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Linda Johannesson; [2022]
    Nyckelord :Biogas production; Biowaste; Manure; Renewable energy; Sustainable energy; Farm-based biogas production; Biogasproduktion; Bioavfall; Gödsel; Förnybar energi; Hållbar energi; Gårdsbaserad biogasproduktion;

    Sammanfattning : För att nå de klimatpolitiska målen arbetar såväl Sverige som EU aktivt mot en cirkulär ekonomi där varje resurs nyttjas så effektivt som möjligt. En del i det arbetet handlar om att lyfta fram hållbara energikällor för att succesivt fasa ut fossila bränslen. LÄS MER

  5. 4. Stimulating national biogas production : The case of Swedish agricultural wastemanagement

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Manoj Dammur; [2020]
    Nyckelord :Biofuels; renewable energy; biogas; Swedish biogas; biogas policies; policies as tools; Anaerobic digestion; waste treatment;

    Sammanfattning : Swedish state has been promoting alternative renewable fuels like biogas to reduce the dependency on fossil fuels and to curb related greenhouse gas emissions. Owing to many policies like subsidies and tax exemptions for using biogas, the country has seen a surge in demand for biogas. LÄS MER

  7. 5. Towards a prototype of a modular biogas system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arvid Emilsson; Andreas Buhrgard; [2019]
    Nyckelord :Biogas; Vehicle gas; CHP; micro-CHP; farm-based; energy audit; techno-economic analysis; energy evaluation; upgrading; water-scrubber; small-scale; scalable; stand-alone; mass-production;

    Sammanfattning : As of today, large unused potential for biogas production exist within the Swedish agriculture sector. The biogas production within this sector is, however, associated with several problems such as poor energy efficiency and non-profitable systems. This is to some degree due to lack of standardized technical solutions. LÄS MER
