  1. 16. Evaluation of emergent macrophytes as a source forbiogas production after mechanical, alkaline and fungalpretreatments.

    University essay from Ekologi; Linköpings universitet

    Author : Simon Alvinge; [2010]
    Keywords : Alkaline; anaerobic digestion; biogas; fungi; plants; pretreatments; milling; wetland.;

    Abstract : Two species of emergent macrophytes, Typha latifolia (common cattail) and Phalaris arundinacea (reed canary grass) were evaluated as substrates for biogas production. The specific methane yield for each plant was obtained by batch wise anaerobic digestion in 300-mL bottles. READ MORE

  3. 17. Integrated production of bioethanol and biogas from agricultural residue : comparison of pretreatment methods using mass flow and energy yields analysis

    University essay from SLU/Dept. of Molecular Biology (until 131231)

    Author : Debebe Yilma Dererie; [2010]
    Keywords : lignocellulose; biofuel; bioenergy; biorefinery; biogas; ethanol; pretreatment; enzymatic saccharification; fermentation;

    Abstract : Lignocellulosic biomasses are believed to reduce the conflict for resource between food and energy production that was criticized in the first generation biofuel production. The aims of this study were two; the first being to compare the effects of three lignocellulose pretreatment methods, lime pretreatment and two steam pretreatment methods, either with or without prior acid impregnation, on the production of bioethanol and biogas from oat straw.

  4. 18. Biomethanation of Red Algae from the Eutrophied Baltic Sea

    University essay from Tema vatten i natur och samhälle

    Author : Rajib Biswas; [2009]
    Keywords : Anaerobic Digestion; Baltic Sea; Biogas; Codigestion; Eutrophication; Nutrients; Pretreatment; Red Algae; Ultrasound; Biodegradation; Renewable Energy; Environmental Science; Chemical Engineering; Environmental Engineering; Process Technology;

    Abstract : In the semi-enclosed Baltic Sea, excessive filamentous macro-algal biomass growth as a result of eutrophication is an increasing environmental problem. Drifting huge masses of red algae of the genera Polysiphonia, Rhodomela, and Ceramium accumulate on the open shore, up to five tones of algae per meter beach. READ MORE

  5. 19. Application of Various Pretreatment Methods to Enhance Biogas Potential of Waste Chicken Feathers

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Azar Khorshidi Kashani; [2009]
    Keywords : chicken feathers; keratin protein; biogas potential; lime treatment; enzymatic treatment; chemo-enzymatic treatment;

    Abstract : Chicken feathers are the most abundant keratinous biomass in the world. Disposal of thehuge and increasing volume of waste feathers presents as a major concern for poultryindustry. On the other hand, energy and material recovery of this valuable protein sourceis an important issue for organic solid waste treatment and bioenergy generation. READ MORE
