2. 1. High-Performance Composites from Modified Wood Fiber

   Author : Mats Westin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kraft lignin; fiberboard; lignocellulosic fiber; durability; wood fiber; mechanical properties; dimensional stability; decay resistance; acetylation; composite;

   Abstract : The objective of this work was to produce and evaluate high-performance wood fiber composites. High-performance was defined as: high dimensional stability and a high durability, including resistance to wood-decaying organisms (fungi, bacteria, and insects). READ MORE

4. 2. Bio-based barriers from wood hydrolysates : A pilot-scale approach

   Author : Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood hydrolysate; biorefinery; oxygen permeability; multilayer barriers; food packaging.; vedhydrolysat; syrgaspermeabilitet; barriärskikt; livsmedelsförpackning;

   Abstract : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition.

5. 3. Design of new bioresourcepackaging from wood hydrolysates

   Author : Soheil Saadatmand; Ulrica Edlund; Monica Ek; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Hemicelluloses are a large group of polysaccharides that have recently attracted considerable attention in many industrial fields due to their abundance and renewability. They are non-edible and possess very good oxygen-barrier properties. READ MORE

6. 4. The Competition for Forest Raw Materials in the Presence of Increased Bioenergy Demand : Partial Equilibrium Analysis of the Swedish Case

   Author : Elina Bryngemark; Patrik Söderholm; Anne Toppinen; Luleå tekniska universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy; biodiversity; partial equilibrium model; forest raw materials; market competition; Sweden; Economics; Nationalekonomi;

   Abstract : Growing energy use and greenhouse gas emissions have implied an increased attention to the development of renewable energy sources. Bioenergy from forest biomass is expected to be one of the cornerstones in reaching renewable energy targets, especially in forest-rich countries such as Sweden. READ MORE
