  1. 11. 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

  3. 12. Optimization of bio-methane production process for combined treatment of sewage & municipal solid waste

    Master-uppsats, KTH/Energiteknik

    Författare :D.W.N Wijesinghe; [2016]
    Nyckelord :;

    Sammanfattning : Handling solid waste such as municipal solid waste (MSW) has become a booming problem in highly populated urban areas. Even though it has a high potential of biogas generation in anaerobic digestion, it is not that successful as a single substrate. LÄS MER

  4. 13. The effects of trace elements on the microbial communities of thermophilic biogas production

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :Robin Hagblom; [2016]
    Nyckelord :biogas; thermophilic; trace elements; ammonia; SAO; fhs;

    Sammanfattning : The increasing need for alternatives to fossil fuels and traditional waste management systems can be simultaneously addressed by the production of biogas using organic waste as input material. The biogas produced can be used directly for energy production or upgraded to increase methane purity for use in the engines of motor vehicles. LÄS MER

  5. 14. Fodder yeast and biogas production: A fruitful symbiosis? : optimization of a single-cell protein process and examination of its impact on biogas output

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :Jonas Ohlsson; [2016]
    Nyckelord :fodder yeast; biogas; nutrient recycling; Wickerhamomyces anomalus; Pichia kudriavzevii; Blastobotrys adeninivorans;

    Sammanfattning : Due to a growing world population and strained wild fish stocks, aquaculture is expected to provide a large part of the increased global demand for animal protein, as the majority of wild fish stocks are already being fished at or above their sustainable capacity. However, fish feed often contains a significant amount of fish meal, produced from wild-caught fish. LÄS MER

  7. 15. Systematic Assessment of Straw as Potential Biogas Substrate in Co-digestion with Manure

    Master-uppsats, Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Författare :Sutina Duong; [2014]
    Nyckelord :Biogas; substrate; straw; systematic assessment; renewable energy; biofertilizer; anaerobic digestion; Biogas; biogassubstrat; halm; systematisk utvärdering; förnybar energi; biogödsel; rötning;

    Sammanfattning : This work was carried out at Biogas Research Center (BRC) and the company Biogas in Vadstena. The aim was to systematically evaluate new substrates for biogas production. In particular, this case investigated the potential of straw in co-digestion with manure and slurry from pig, chicken and dairy. LÄS MER
