  1. 21. A value-added mechanism in optimising biogas production with biochar pyrolysis products

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Pius Nyuykonge Lukong; [2018]
    Nyckelord :;

    Sammanfattning : While biogas stands a greater chance in substituting fossils fuels and contributing to the reduction of GHG emissions, its major setbacks still rely on its effective price compared to that of fossil fuels in the world market. Its production efficiency and related operational cost can give it a true competitive meaning to fossil fuels regarding upgrading and logistic cost of handling digestate. LÄS MER

  3. 22. Glucose Levulinates as Bio-plasticizers

  5. 24. 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. 25. Assessment of changes in algal biomass accrual and leaf decomposition along a gradient of increasing agricultural dis-turbance

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Maisam Ali; [2015]
    Nyckelord :leaf decomposition; algal biomass accrual; stream biodiversity;

    Sammanfattning : 1. Anthropogenic activities may impact stream ecosystems by distorting the energetic linkages between the aquatic and adjacent terrestrial habitats, or by modifying the aquatic environment directly. LÄS MER
