  1. 1. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

    Författare :Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

    Sammanfattning : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. LÄS MER

  3. 2. Evaluation of Pretreatment and Process Configurations for Combined Ethanol and Biogas Production from Lignocellulosic Biomass

    Författare :Pia-Maria Bondesson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; biogas; lignocellulose; steam pretreatment; acid catalyst; acetic acid; phosphoric acid; sulphuric acid; xylose fermentation; co-fermentation; process design; SSCF;

    Sammanfattning : In view of global climate change and the increasing energy demand there is a need for renewable energy resources. This thesis discusses an energy-driven biorefinery concept based on the agricultural residues corn stover and wheat straw. The work is divided into two main parts. LÄS MER

  4. 3. Biogas from agricultural waste : Turning unavailable residues into accessible resources

    Författare :Mirjam Victorin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Straw; Manure; Pretreatment; Process design;

    Sammanfattning : Moving from a fossil dependent to a fossil free economy requires increased energy production from renewable resources. This thesis discusses the utilization of agricultural waste streams, such as straw and manure, for biogas production. LÄS MER

  5. 4. Developments in Feedstock Analysis and Process Control for Biogas Production

    Författare :Sten Strömberg; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Sammanfattning : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. LÄS MER

  7. 5. Multiple Imaginaries of the Fossil Fuel Free Future : Biogas and Electricity in Swedish Urban Transport

    Författare :Amelia Mutter; Harald Rohracher; Jane Summerton; Magdalena Kuchler; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sociotechnical imaginaries; biogas; electric vehicles; obduracy; sociotechnical change; urban transport; sociotekniska föreställningar; biogas; elfordon; tröghet; sociotekniska förändring; stadstrafik;

    Sammanfattning : I kölvattnet av klimatkrisen har det blivit allt tydligare att det fossilbaserade transportsystemet måste genomgå en global omvandling. Många alternativ för förnyelsebara drivmedel har föreslagits, alla omgivna av föreställningar om hur dessa tekniker kommer att bidra till en bättre framtid. LÄS MER
