  1. 6. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Författare :Sara Jonsdottir Glaser; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Sammanfattning : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries. LÄS MER

  3. 7. Exploring the relevance of uncertainty in the life cycle assessment of forest products

    Författare :Frida Røyne; Mats Tysklind; Stina Jansson; Johanna Berlin; José Potting; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; wood; forestry; uncertainty; biorefinery; industrial symbiosis; allocation; system boundaries; bio-economy; LCA; trä; skogsbruk; osäkerhet; bioraffinaderi; industriell symbios; allokering; systemgränser; bioekonomi;

    Sammanfattning : The role of forest biomass as a replacement for fossil fuels and products is becoming increasingly prominent as a means to mitigate climate change. To guide a sustainable transition towards a forest-based bio-economy, it is important that advantages and disadvantages of forest products are assessed, to ensure that the products deliver environmental impact reduction.

  4. 8. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

    Författare :Rosa Aragao; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

    Sammanfattning : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. LÄS MER

  5. 9. Time and spatial dependent climate impact of grass cultivation and grass-based biogas system

    Författare :Johan Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One strategy to limit global warming is to phase out fossil products and replace them with bio-based alternatives. This is often referred to as transitioning from a fossil economy to a bioeconomy. LÄS MER

  7. 10. Chemical Modification of Cellulose Nanocrystals: Creating a Novel Toolbox Utilising the Overlooked Sulphate Surface Groups

    Författare :Karin Sjövold; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Composites; Scale-up; Dialkylamines; Cellulose nanocrystals; Azetidinium salts; Chemical modification; Thermal stability;

    Sammanfattning : The move towards a bio-based economy has created an increasing demand for renewable, sustainably produced materials. For future generations, it is crucial to develop economically, socially and environmentally sustainable materials and processes. LÄS MER
