    Sammanfattning : Burgeoning concerns on the adverse environmental impacts of fossil-derived products are propelling the pursuit of material production from sustainable resources. Resource recovery from waste is a key component of meeting the environmental sustainability agendas set by the United Nations. LÄS MER

  4. 13. Ethanol from Softwood - Techno-Economic Evaluation for Development of the Enzymatic Process

    Författare :Anders Wingren; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; process development; process simulation; ethanol production; Chemical technology and engineering; economic evaluation; softwood;

    Sammanfattning : Ethanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. LÄS MER

  5. 14. Microbial Ecosystem Functions Along the Steep Oxygen Gradient of the Landsort Deep, Baltic Sea

    Författare :Petter Thureborn; Sara Sjöling; Mats Grahn; Matthias Labrenz; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial ecology; ecosystem functions; microbial community; bacteria; archaea; metagenomics; metatranscriptomics; oxygen gradient; hypoxia; sediment; Baltic Sea; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Through complex metabolic interactions aquatic microbial life is essential as a driver of ecosystem functions and hence a prerequisite for sustaining plant and animal life in the sea and on Earth. Despite its ecological importance, infor­mation on the complexity of microbial functions and how these are related to environmental conditions is limited. LÄS MER

  7. 15. Utilizing CO2 from biomethane production : Sustainability and climate performance

    Författare :Stephanie S. Cordova; Mats Eklund; Marcus Gustafsson; Niclas Svensson; Valentina Bisinella; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; Carbon capture and utilization; CCU; CO₂ utilization;

    Sammanfattning : Biogas solutions offer many benefits for the environment and society, including organic waste treatment as well as being an enabler for energy and nutrient recovery. The products of anaerobic digestion are a biogas, which contains a share of 30 to 50% carbon dioxide (CO2) and 50 to 70% methane, and a liquid remanent, rich in nutrients. LÄS MER
