  1. 1. Waste-integrated biorefineries : A path towards efficient utilization of waste

    Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. LÄS MER

  3. 2. Innovation for biorefineries – Networks, narratives, and new institutions for the transition to a bioeconomy

    Författare :Fredric Bauer; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioeconomy; biorefineries; innovation; socio-technical transitions;

    Sammanfattning : The transition to a bioeconomy is dependent on transformative changes to technologies, organisations, and institutions, which jointly can be described as a socio-technical change. The thesis contributes to the understanding of how the transition is shaped by expectations on and collaborations for innovation forbiorefineries, which can produce chemicals, fuels, and materials needed in a bioeconomy.

  4. 3. Resource mobilisation for energy system transformation

    Författare :Kersti Karltorp; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Resource mobilisation; Biorefineries; Energy system transformation; Offshore wind power; Incumbent firms; Competences;

    Sammanfattning : A transition to a sustainable path of development will require that fossil fuels are replaced with renewable energy sources and involve, therefore, a large-scale transformation of the energy system. In the EU, offshore wind power and biorefineries have the potential to play an important role in this transformation. LÄS MER

  5. 4. SCALING UP RENEWABLE ENERGY TECHNOLOGIES - The role of resource mobilisation in the growth of technological innovation systems

    Författare :Kersti Karltorp; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; resource mobilisation.; scaling up technologies; Wind power; technological innovation system; biorefineries;

    Sammanfattning : Rapid and large-scale diffusion of renewable energy technologies is needed to avoid severe climate changes that would dramatically affect the conditions for human life on Earth. To scale up these technologies involves technological development, but also the alteration of structures that are locked-in to established socio-technical systems. LÄS MER

  7. 5. Dicarboxylic acids from xylose, using natural and engineered hosts

    Författare :Henrik Almqvist; Institutionen för kemiteknik; []
    Nyckelord :Xylose; Dicarboxylic Acids; Biorefineries; Actinobacillus succinogenes; Basfia succiniciproducens; Saccharomyces cerevisiae; Caulobacter crescentus;

    Sammanfattning : Chemical building blocks for plastics can be produced from renewable biomass feedstocks using microbial production organisms, such as yeast or bacteria, in a biorefinery. One class of chemical building blocks that are suitable for production of biobased and biodegradable plastics are dicarboxylic acids, e.g. succinic acid. LÄS MER
