  1. 26. 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

  3. 27. Biogas from slaughterhouse waste : Mixtures interactions in co-digestion

    Författare :Jhosané Pagés Diaz; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slaughterhouse waste; Agro-Waste; Co-digestion; Synergistic effects; Methanogenic community structure; Resource Recovery; Resursåtervinning;

    Sammanfattning : Global environmental concerns connected to the use of fossil fuels have forced the development ofalternative sustainable energy technologies. The application of anaerobic digestion, from waste streams thatcurrently have no use, can be utilized for bioenergy production. LÄS MER

  4. 28. Industrial Bioprocess Developments for Biogas and Ethanol Production

    Författare :Karthik Rajendran; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; ethanol; process design; techno-economic analysis; simulation; modeling; Resource Recovery; Resursåtervinning;

    Sammanfattning : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. LÄS MER

  5. 29. Properties and performance of regenerated cellulose thermoset biocomposites

    Författare :Sunil Kumar Ramamoorthy; Jyrki Vuorinen; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; regenerated cellulose fibres; surface modification; alkali; silane; mechanical analysis; biocomposites; renewable resources; Resursåtervinning; Resource Recovery;

    Sammanfattning : Biocomposites have been developed to address the sustainability issues of nonrenewableresource based materials. These composites are often produced by reinforcing natural fibres in petroleum based thermoset resins or thermoplastic polymers. LÄS MER

  7. 30. Improving cyanobacteria productivity: From theory to assay

    Författare :Kiyan Shabestary; Elton P. Hudson; Daniel Ducat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; growth-coupling; growth-arrest; cyanobacteria; CRISPRi; CRISPRi library; flux balance analysis; genome-scale model; butanol; lactate; isoprene; Bioteknologi; Biotechnology;

    Sammanfattning : Bio-based production of biochemicals and biofuels holds great promises for the transition towards a more sustainable society. With increasing levels of carbon dioxide (CO2) in the atmosphere, cyanobacteria stand apart as natural catalysts directly converting CO2 and light to product. LÄS MER
