  1. 1. 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

  3. 2. Thermochemical energy utilization of biomass in Rwanda - a screening of potential feedstocks

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Nyckelord :bioenergy; agricultural; residues; waste; agroforestry; africa; energiteknik; bioenergi; jordbruksrester; afrika; termokemisk; bränslen;

    Sammanfattning : Traditional bioenergy practices in sub-Saharan Africa involve collecting natural forest wood and burning it in simple fireplaces for household cooking. This is actually still very common, especially in rural areas. The situation is unfortunately connected to health issues, inequality and natural forest degradation and deforestation. LÄS MER

  4. 3. The Biogas Sector Development : Current and future trends in Western and Northern Europe

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Laurent Geerolf; [2018]
    Nyckelord :;

    Sammanfattning : The following study attempts to provide a comparative analysis of the biogas production activities in 15 countries in Western and Northern Europe. The goal is, for each country, to gather all the available information about the present status of the biogas sector and then to evaluate the possible trends for future development in terms of main biogas production pathways, valorization, volumes, market dynamics, etc. LÄS MER

  5. 4. Självförsörjande hushåll med biogasproduktion och akvaponi

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emil Sund; [2018]
    Nyckelord :Biogas; aquaponics; urban farming; Biogas; akvaponi; urban odling;

    Sammanfattning : Energiförsörjningsteknologier behöver avanceras, oberoende av var i världen och i vilket syfte. Fossila bränslen bidrar till kraftiga växthusgasutsläpp när de förbränns och kretsloppet för dessa råvaror är en långsam process. LÄS MER

  7. 5. Implementation of renewable energy in the Republic of Moldova : society and landscape in transition

    Master-uppsats, SLU/Landscape Architecture (until 121231)
