1. 1. 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

3. 2. Evaluation of pre-fermentation using confectionery waste products for two-stage anaerobic digestion

   Uppsats för yrkesexamina på avancerad nivå, Tema vatten i natur och samhälle

   Författare :Björn Magnusson; [2010]
   Nyckelord :pre-fermentation; confectionery waste products; two-stage process; anaerobic digestion; biogas;

   Sammanfattning : The finite amount of energy carriers affects all of us. It is important to utilize all available sources and to find new sources of energy. The confectionery industry generates both solid and liquid waste during the production of confectioneries, which could be utilized as a substrate for biogas production. LÄS MER

4. 3. Thermal pre-treatment of cellulose rich biomass for biogas production

   L3-uppsats, SLU/Dept. of Microbiology

   Författare :Pauline Demetriades; [2008]
   Nyckelord :biogas production potential; degradation rate; degradation potential; thermal pre-treatment; steam explosion; autohydrolysis; cellulose; lignin; oat straw; meadow grass; aspen; spruce; wet grain residue; batch experiment;

   Sammanfattning : Anaerobic digestion is one possible method to produce bioenergy from cellulose rich materials but the process techniques still need refinements to facilitate the production process. In this work the biogas potential from six different plant materials was evaluated and what effect a thermal pre-treatment had on this potential. LÄS MER

5. 4. Masugnsslaggens potential som filtermaterial för metaller i vägdagvatten

   Magister-uppsats, Institutionen för samhällsteknik

   Författare :Michael Skogsfjord; Minna Blom; [2008]
   Nyckelord :column studies; batch studies; lead; copper; zinc; stormwater; iron slag; dagvatten; masugnsslagg; hyttsand; kolonnförsök; batchförsök; bly; koppar; zink;

   Sammanfattning : Dagvatten från vägar innehåller ofta tungmetaller. De vanligaste metallerna i vägdagvatten är bly, koppar, kadmium, nickel och zink. Dessa föroreningar utgör en belastning i recipienter som tar emot dagvattnet. LÄS MER
