2. 1. Wood hydrolysate Barriers

   Author : Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

   Abstract : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. READ MORE

4. 2. Selective Separation Of Wood Components In Internal Process Waters Originating From Mechanical Pulping

   Author : Dariusz Zasadowski; Magnus Norgren; Bjarne Holmbom; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; flotation; foaming agents; chelating surfactant; TMP process water; pitch control; internal cleaning stage; hemicellulose recovery; anti‐solvents; solvents; precipitation;

   Abstract : Dissolved and Colloidal substances (DSC) and metals are released from woodduring thermomechanical pulp (TMP) production. These components have atendency to accumulate in process waters, as the water circulation systems inintegrated paper mills are closed. READ MORE

5. 3. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

   Author : Alexandra Andersson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

   Abstract : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. READ MORE

6. 4. Separation of Biomass Components by Membrane Filtration - Process Development for Hemicellulose Recovery

   Author : Holger Krawczyk; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; hemicelluloses; pulp mill process water; alkaline extract; membrane filtration;

   Abstract : One of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. 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
