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

    Författare :Anna Teghammar; Högskolan i Borås; []
    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;

    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

  3. 2. Zygomycetes and cellulose residuals : hydrolysis, cultivation and applications

    Författare :Patrik Lennartsson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zygomycetes; fungi; lignocelluloses; ethanol; fish feed; animal feed; dimorphism; airlift; pretreatment; Biotechnology; Resursåtervinning; Resource Recovery;

    Sammanfattning : Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. LÄS MER

  4. 3. Pretreatment of cellulosic waste and high rate biogas production

    Författare :Solmaz Aslanzadeh; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Sammanfattning : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. LÄS MER

  5. 4. Bioprocessing of Recalcitrant Substrates for Biogas Production

    Författare :Maryam M Kabir; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; biogas; lignocellulose; wool; keratin; pre-treatment; co-digestion; dry digestion; economic evaluation; Resursåtervinning; Resource Recovery;

    Sammanfattning : The application of anaerobic digestion (AD) as a sustainable waste management technology is growing worldwide, due to high energy prices as well as increasingly strict environmental regulations. The growth of the AD industry necessitates exploring new substrates for their utilisation in AD processes. LÄS MER

  7. 5. DIFFUSION OF IONS IN WOOD

    Författare :Reddysuresh Kolavali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium chloride; impregnation; diffusion; Norway spruce; local concentration profiles; experimental methodology; micro-cracks; wood; Donnan effect;

    Sammanfattning : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. LÄS MER
