  1. 6. The effect of thermal pre-treatment and waste paper addition to biomethane potential of macro algae Saccharina lattissima

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Gadis Tandiyoputri; [2018]
    Nyckelord :biomethane potential; macroalgae; Saccharina Lattissima; mechanical pre-treatment; thermal pre-treatment;

    Sammanfattning : As a steady renewable energy technology, biogas is a viable alternative to reduce our dependency to fossil fuels and to prevent severe climate change. Biogas potential can be improved through combining different types of substrate and inoculum, as well as through substrate pre-treatments. LÄS MER

  2. 7. Feasibility study for producing and using biogas in Chisinau, Moldova

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

    Författare :Johanna Alander; Adam Nylin; [2018]
    Nyckelord :Biogas; Biofertilizer; Biomethane; Potential; Feasibility; Chisinau; Moldova; Sustainable cities;

    Sammanfattning : More and more people live in cities, cities that both present opportunities, in terms of potential sustainable growth and challenges, for example regarding insufficient infrastructure and waste management. There are several examples on initiatives to make cities reach their sustainability potential; one is to turn municipal organic waste, MOW, and sewage sludge into biogas and use it to produce electricity and/or heat or to upgrade it to biomethane and use it as a fuel in for example public transport or feed it to a gas grid.

  3. 8. If we buy your vehicles, can we produce our own fuel? : An early assessment method for the market expansion of biomethane solutions

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

    Författare :Axel Lindfors; Sofie Lärkhammar; [2017]
    Nyckelord :biomethane; system analysis; multi-criteria approach; early assessment method; early assessment tool; heavy-duty vehicle;

    Sammanfattning : Biomethane made from the anaerobic digestion of organic waste can provide several economic and environmental benefits such as: the valorisation of waste products, increased resource efficiency, increased retention of nutrients through recycling of biogas digestate (Banks, et al., 2011), reduction of greenhouse gas emissions (Börjesson, et al.

  4. 9. Biomethane via Woodroll® - Investigation of Revenues & Profitability Analysis

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Robert Andersson Krohn; [2016]
    Nyckelord :Woodroll; biomethane; biomass gasification; feed-in tariff; revenues; risks; Woodroll; biometan; biomassaförgasning; inmatningstariff; intäkter; risker;

    Sammanfattning : Woodroll® is a gasification technology developed by Cortus that produces synthetic gas (syngas) from biomass. Syngas can be used in several different applications. One interesting option is to convert it further into biomethane, which can be used as automotive fuel or replace natural gas in gas grids. LÄS MER

  5. 10. Improving methane production using hydrodynamic cavitation as pre-treatment

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Louise Abrahamsson; [2016]
    Nyckelord :Hydrodynamic cavitation; steam explosion; anaerobic digestion; hydrolysis; bmp; particle size distribution; methane; particle size reduction; food waste; sludge; grass; biogas; energy; renewable energy; Scandinavian biogas fuels AB; Scandinavian biogas; cavitation; biogas production; biomethane potential; Linköping university; Hydrodynamisk kavitation; kavitation; ångexplosion; rötning; anaerob rötning; hydrolys; BMP; partikelstorlekreducering; biometanpotential; biogas; metan; metangas; alger; saccharina latissima; ascophyllum nodosum; gräs; matavfall; avloppsslam; förnybar energi; Linköpings universitet; examensarbete biogas; examensarbete kavitation;

    Sammanfattning : To develop anaerobic digestion (AD), innovative solutions to increase methane yields in existing AD processes are needed. In particular, the adoption of low energy pre-treatments to enhance biomass biodegradability is needed to provide efficient digestion processes increasing profitability. LÄS MER
