2. 6. Fungi-based biorefinery model for food industry waste : progress toward a circular economy

   Author : Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filamentous fungi; circular economy; biorefinery; food industry; fungal biomass; bioplastic; resource recovery; Resource Recovery; Resursåtervinning;

   Abstract : The food industry, one of the most important industrial sectors worldwide, generates large amounts of biodegradable waste with high organic load. In recent years, the traditional management methods to treat this waste (e.g., landfilling) have been considered not suitable because they do not exploit the potential of the waste material.

4. 7. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

   Author : Tarek Dishisha; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

5. 8. Syngas production by integrating thermal conversion processes in an existing biorefinery

   Author : Katarina Åberg; Anders Nordin; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

   Abstract : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. READ MORE

6. 9. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

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

   Abstract : 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. READ MORE

7. 10. Pre-Extraction of Wood Components Mild hydrothermal methods for a future materials biorefinery

   Author : Joanna Wojtasz-Mucha; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spruce; forest residues; pre-treatment; Biorefinery; soda cooking; hot water extraction; steam explosion; autohydrolysis; birch; kraft cooking;

   Abstract : Today there is an increasing urgency in discovering new, and more sustainable, replacements for fossil-based materials and chemicals. The biorefinery concept is promising in this context in that it relies on transforming biomass into a spectrum of commercial products. Wood is the primary bioresource in Scandinavia. READ MORE
