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

   Author : Fredric Bauer; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioeconomy; biorefineries; innovation; socio-technical transitions;

   Abstract : 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. 2. Added value from biomass by broader utilization of fuels and CHP plants

   Author : Christer Gustavsson; Roger Renström; Lars Nilsson; Pål Börjesson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; bioeconomy; pyrolysis; gasification; leaching; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : The present work, where additional value-creating processes in existing combined heat and power (CHP) structures have been examined, is motivated by a political- and consumer-driven strive towards a bioeconomy and a stagnation for the existing business models in large parts of the CHP sector.The research is based on cases where the integration of flash pyrolysis for co-production of bio-oil, co-gasification for production of fuel gas and synthetic biofuels as well as leaching of extractable fuel components in existing CHP plants have been simulated.

5. 3. Process development and environmental assessment within softwood based biorefineries

   Author : Karin Carlqvist; Avdelningen för kemiteknik; []
   Keywords : 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;

   Abstract : 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).

6. 4. Circular bioeconomy through valorisation of agro-industrial residues by the edible filamentous fungus Neurospora intermedia

   Author : Rebecca Gmoser; Mohammad J Taherzadeh; José António Teixeira; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neurospora intermedia; mycoprotein; carotenoids; feed; solid-state fermentation; circular bioeconomy; Resource Recovery; Resursåtervinning;

   Abstract : Prevention of dramatic climate change and ensuring food and nutrition security for subsequent generations necessitates the reduction of greenhouse gas emissions and efficient use of the world’s resources, including efficient waste disposal. The agro-industrial sector generates a large amount of organic waste, that is currently underexploited owing to poor waste management practices. READ MORE

7. 5. How do biogas solutions influence the sustainability of bio-based industrial systems?

   Author : Linda Hagman; Mats Eklund; Niclas Svensson; Thomas Prade; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; biorefinery; biomass; circular bioeconomy; sustainability; feasibility; stakeholders; assessments; methods;

   Abstract : Biomass is a valuable and limited resource that should be used efficiently. The potential of replacing fossil-based products with bio-based ones produced in biobased industrial systems is huge. One important aim of increasing the share of biobased products is to improve the sustainability of systems for production and consumption. READ MORE
