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. Creating value from bio-residuals : Biogas solutions for biobased industries in Scandinavia

   Författare :Linda Hagman; Mats Eklund; Niclas Svensson; Kari-Anne Lyng; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Biobased industry; Resource efficiency; Biogas development; Sustainability; Nutrients; Biogas; Biobaserad industri; Resurseffektivitet; Biogasutveckling; Hållbarhet; Näring;

   Sammanfattning : This thesis focuses on biogas solutions for biobased industries as substrate management or energy providers. It investigates how such solutions are set up, what factors are important for their development, the effects on society and biobased industries, and the possibility of having biogas solutions as part of a sustainability strategy for biobased industries.

4. 3. Fuel Cells and Biogas

   Författare :Lars Hedström; Per Alvfors; Peter Lund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

   Sammanfattning : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. LÄS MER

5. 4. Design and development of a novel textile based bioreactor: : Ethanol and biogas production as case studies

   Författare :Osagie Alex Osadolor; Christian Larroche; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; bioreactor; bioreactor design; techno-economic analysis; membrane stress analysis; mass transfer; hydrodynamics; Resource Recovery; Resursåtervinning;

   Sammanfattning : Bioreactors are designed to provide enabling conditions for the controlled growth of microorganisms, such as good heat and mass transfer, aeration, hydrodynamics, geometry for adequate gas holdup, pH and foaming control, conditions for optimal substrate consumption and product formation, as well as mechanisms for monitoring microbial conditions. Additionally, bioreactors are designed to handle stress that would be exerted on them by the weight of the fermenting media and by the high pressure used for sterilisation. LÄS MER

7. 5. Combined Energy Solutions Applied to Dairy Farming in Bolivia and Latin America

   Författare :Johnny Villarroel-Schneider; Andrew R. Martin; Anders Malmquist; Valentina Zaccaria; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; productive sector; dairy farm; farming; biogas; energy efficiency; electricity; refrigeration; self-sufficiency; techno-economic; GHG emissions; Bolivia; Latin America; Polygeneration; produktiv sektor; mjölkgård; jordbruk; biogas; energieffektivitet; elektricitet; kylning; självförsörjning; teknisk-ekonomisk; växthusgasutsläpp; Bolivia; Latinamerika; Poligeneración; sector productivo; granja; ganadería; biogás; eficiencia energética; electricidad; refrigeración; autosuficiencia; tecno-económico; GEI; Bolivia; América Latina; Energiteknik; Energy Technology;

   Sammanfattning : The transition towards a sustainable world requires immediate action on the part of individuals and communities. Developing countries find the task of incorporating climate change policies difficult for various reasons including the negative effects that the Covid-19 pandemic left behind on the economy. LÄS MER
