2. 1. Agro-Waste Derived Additives for Polylactide and Tapioca Starch

   Author : Edwin Azwar; Minna Hakkarainen; Anna Wistrand; Christian Glandfils; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agro-industrial waste; wood flour; rice bran; polylactide; starch; biomass; degradation; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

   Abstract : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. READ MORE

4. 2. 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

5. 3. Chemical characterization in the biorefinery of lignocellulose : Formation and management of oxalic acid and analysis of feedstocks for bioethanol production

   Author : Anders Sjöde; Nils-Olof Nilvebrant; Leif J. Jönsson; Arthur J. Ragauskas; Karlstads universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biorefinery; enzymes; ethanol; lignocellulosic feedstocks; oxalic acid; scaling; Biochemistry; Biokemi; Kemi; Chemistry;

   Abstract : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. READ MORE

6. 4. Fungi-Based Biorefinery : Valorization of industrial residuals and techno-economic evaluation

   Author : Gülru Bulkan; Mohammad J Taherzadeh; Mats Galbe; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Techno-economic analysis; Organosolv; bioethanol; filamentous fungi; food; lignin; fruit; bioactive compounds; Resource Recovery; Resursåtervinning;

   Abstract : Sustainable development of society and industry is necessary for a safer future that is being challenged by environmental pollution, climate change, and scarcity of food and nutrition. Materials considered as waste can be converted into value-added products and energy, hence regained to the economy. READ MORE

7. 5. 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
