  1. 16. Improving methane production using hydrodynamic cavitation as pre-treatment

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Louise Abrahamsson; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 17. Production and biodegradability of dissolved organic carbon from dIfferent litter sources

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Carlos Arellano; [2015]
    Keywords : biogeochemical cycles; physical geography and ecosystem analysis; dissolved organic carbon; carbon cycle; soil biogeochemistry; Earth and Environmental Sciences;

    Abstract : The movement of carbon on Earth is based on exchange between pools that represent carbon in different physical forms, differing in chemical composition, structure and function. Dissolved organic carbon plays an important role in ecosystems because of its mobility, which can be relatively high in saturated soils, and because it is the most available fraction of organic matter for microorganisms in soil, being particularly active in microbial degradation processes through soil profile.

  4. 18. Assembly of whey protein nanofibrils into macroscopic filaments

    University essay from KTH/Mekanik

    Author : Kamada Ayaka; [2015]
    Keywords : ;

    Abstract : Recently, it has been reported that the increasing number of plastic are significantly floated in the sea, because they are difficult to be degraded naturally. This lack of biodegradability requires us to develop new environmental-friendly material replacing current plastics. READ MORE

  5. 19. COD fractionation of wastewater on cruise liners before and after advanced treatment

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Karin Ekström; Jenni Borg; [2015]
    Keywords : Chemical oxygen demand; COD; biodegradability; wastewater; permeate; water treatment; cruise liners; analytical chemistry; ozonation; nanofiltration; physiochemical method;

    Abstract : The purpose of this Bachelor thesis was to establish a method for determining the chemical oxygen demand (COD) fractionation in wastewater from cruise liners. COD fractions of interest were soluble biodegradable (SS), particulate biodegradable (XS), soluble unbiodegradable (SI) and particulate unbiodegradable (XI). READ MORE

  6. 20. Systematic Assessment of Straw as Potential Biogas Substrate in Co-digestion with Manure

    University essay from Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

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

    Abstract : 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. READ MORE
