  1. 21. Evaluation of a biogas process co-digesting slaughterhouse waste and swine manure : impact of increased organic loading and addition of iron

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Sara Ericsson; [2017]
    Nyckelord :biogas;

    Sammanfattning : Anaerobic digestion by microorganisms generate methane which can be used as a renewable source of energy. A complex biological system with a community of microorganisms that work together can be used for generation of methane from substrates such as household wastes and agricultural wastes. LÄS MER

  3. 22. Investigation of biochemical methane potential in Thái Nguyên city and Sông Công city in Vietnam

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Anurag Deo; Mette Axelsson Bjerg; [2017]
    Nyckelord :Substrate Investigation; Biogas; Biochemical Methane Potential Tests; BMP; Brewery Waste; Food Waste; Waste Water Treatment Plant sludge; WWTP; Vietnam;

    Sammanfattning : Currently Vietnam is facing several problems with waste handling. For instance, a lot of the municipal organic solid waste is dumped at landfills, which contributes to environmental difficulties such as greenhouse gas emissions. LÄS MER

  4. 23. Distributed biogas production for biogas fuel

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Bilal Shah; [2017]
    Nyckelord :;

    Sammanfattning : Regeringen har en vision om ett Sverige ska ha en fossiloberoende fordonsflotta år 2050. Transportsektorn står idag för en fjärdedel av Sveriges energianvändning och använder sig till 80 % av fossila bränslen. LÄS MER

  5. 24. Optimal processtemperatur vid mesofil samrötningsprocess

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Henrik Nilsson; [2016]
    Nyckelord :mesofil samrötning; Biogas; processtemperatur; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental engineering; Technology and Engineering;

    Sammanfattning : The purpose of this master thesis has been to investigate how a change in process temperature can affect the stability and production of biogas. The plant which is operated and administrated by OX2 Bio Produktion AB located in Helsingborg produces biogas from primarily household food waste and waste from food industry. LÄS MER

  7. 25. Start–up of a Thermophilic Digestion of Sewage Sludge from Mesophilic Conditions.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :George Asimakopoulos; [2016]
    Nyckelord :;

    Sammanfattning : The purpose of this Master thesis is to study two different ways of start-up in anaerobic digesters under thermophilic conditions. As awareness for energy supply is growing, municipal waste water treatment uses a common treatment to stabilize sewage sludge which is called, anaerobic digestion (AD). LÄS MER
