  1. 1. Biogas Production from Citrus Wastes and Chicken Feather Pretreatment and Co-digestion

    Detta är en avhandling från Chalmers University of Technology

    Författare :Gergely Forgács; Högskolan i Borås.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Recovery; Resursåtervinning; anaerobic digestion; pretreatments; co-digestion; economic analyses; citrus wastes; feather; Energi; material; Bioteknik; Bioengineering;

    Sammanfattning : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.

    Sammanfattning : Popular Abstract in Swedish TARMENS UPPTAG AV GALAKTOLIPIDER Världens vanligaste fettmolekyler Inuti cellerna hos alla växter finns en komponent som kallas kloroplast. I kloroplasten sker den livsviktiga fotosyntesen där energi från solljuset omvandlar koldioxid och vatten till socker och syre. LÄS MER

  3. 3. Biogas Production from Lignocelluloses Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

    Detta är en avhandling från Chalmers Tekniska Högskola

    Författare :Anna Teghammar; Högskolan i Borås.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology; economic evaluation.;

    Sammanfattning : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. LÄS MER

  4. 4. Anaerobic Digestion – Microbial Ecology, Improved Operational Design and Process Monitoring

    Detta är en avhandling från Siv Holmqvist, Department of Biotechnology, Lund University

    Författare :Marika Murto; Lunds universitet.; Lund University.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monitoring; UASB; Biotechnology; Bioteknik; methanogens; fluorescence in situ hybridisation; FISH; co-digestion; biogas; biofilm; aqueous two phase system; anaerobic digestion; 16S rDNA; alkalinity;

    Sammanfattning : The implementation of anaerobic digestion is important in the concept of sustainable development, especially regarding the environmental benefits. Biogas is produced when organic matter is degraded by microorganisms under oxygen-free (anaerobic) conditions. LÄS MER

  5. 5. Anaerobic digestion of horse manure renewable energy and plant nutrients in a systems perspective

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Åsa Hadin; Högskolan i Gävle.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER
