  4. 3. 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

  5. 4. Decarbonising plastics – On the technologies and framings of carbon capture and utilisation

    Författare :Ellen Palm; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastics; Carbon capture and utilisation; Carbon circularity; Industrial decarbonisation; Climate mitigation; Interdisciplinarity;

    Sammanfattning : Plastics consist of fossil fuels, from both a feedstock and energy perspective and thus need to decarbonise. This thesis maps and explores the framings and technologies that surround plastics decarbonisation and the potential mitigation pathway of carbon capture and utilisation. Here, three of the main findings are presented. LÄS MER

  7. 5. Development of a method for highly localized growth of carbon nanotubes

    Författare :Staffan Dittmer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; chemical vapour deposition; low temperature CVD; local heating; resistive growth; Carbon nanotubes;

    Sammanfattning : A method for growing carbon nanotubes on chip using highly localizedresistive heating is developed. By deliberately designing molybdenumelectrodes to be highly resistive in a very small region we create amicrometer sized hot-zone where carbon nanotubes can be grown. LÄS MER
