   Sammanfattning : The production of biofuels has increased in recent years, to reduce the dependence on fossil fuels and mitigate climate change. However, current production practices are heavily criticized on their environmental sustainability. LÄS MER

4. 23. Process development and environmental assessment within softwood based biorefineries

   Författare :Karin Carlqvist; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar platform; extractives; steam explosion; pretreatment; bark; enzymatic hydrolysis; phenolic compounds; bioeconomy; LCA; Pinus sylvestris; Picea abies; pine; spruce; sockerplattform; extraktivämnen; Steam explosion SE ; förbehandling lignocellulosa; bark; enzymatisk hydrolys; fenoler; bioekonomi; LCA; Pinus sylvestris; Picea abies; tall; gran;

   Sammanfattning : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).

5. 24. Design of kinetic models for assessment of critical aspects in bioprocess development : A case study of biohydrogen

   Författare :Johanna Björkmalm; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic models; biohydrogen; Caldicellulosiruptor; substrate; diauxic; inhibition; osmotolerance;

   Sammanfattning : The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. LÄS MER

7. 25. Land Use Conflicts between Agriculture and Energy Production : Systems Approaches to Allocate Potentials for Bioenergy and Agrophotovoltaics

   Författare :Daniel Ketzer; Peter Schlyter; Henrik Ny; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energies; Geographic Information Systems; Agrophotovoltaics; Participatory technology development; Responsible Research and Innovation; Physical Geography; naturgeografi;

   Sammanfattning : The developments towards a bio-based economy and a renewable energy-based power supply require thorough assessments of feedstocks and frameworks. In the past, political targets for increasing shares of renewable energies for combatting climate change have triggered direct land use changes (LUCs) and even indirect land use changes (iLUCs).
