2. 1. Bark Biorefinery : Isolation, Characterization and Application

   Author : Isabella Kwan; Monica Ek; Åsa Emmer; Anette Larsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sustainability; bark; biorefinery; Norway spruce; nanocellulose; Pickering emulsion; organosolv; extraction; lignin; Hållbarhet; bark; bioraffinaderi; gran; nanocellulosa; Pickering emulsioner; organosolv; extraktion; lignin; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. READ MORE

4. 2. Palladium-catalyzed lignin valorization : Towards a lignin-based biorefinery

   Author : Maxim Galkin; Joseph Samec; Rafael Luque; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lignin; Heterogeneous Catalysis; Palladium; Biomass; Depolymerization; Reduction; Oxidation; Biorefinery; Transfer Hydrogenolysis; Organic Chemistry; Organisk kemi;

   Abstract : The work described in this thesis focuses on the cleavage of the β-O-4′ bond, which is the most abundant interunit linkage in the lignin polymer.In the first part, three methods based on palladium catalysis have been developed and their applicability has been verified using lignin model compounds.

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. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation

   Author : Mohsen Parchami; Mohammad J Taherzadeh; Sudip Rakshit; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brewer s spent grain; Hydrothermal pretreatment; Organosolv pretreatment; Edible filamentous fungi; Anaerobic digestion; Biorefinery; Resource Recovery; Resursåtervinning;

   Abstract : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. READ MORE
