1. Strategies for building polymers from renewable sources : Using prepolymers from steam treatment of wood and monomers from fermentation of agricultural products
Sammanfattning : A strategic research area today is development of polymericproducts made from renewable sources. The ways of utilizingrenewable sources studied in this thesis are using 1)prepolymers obtained by steam treatment of wood and 2) monomersobtainable by fermentation of agricultural products. LÄS MER
2. Wood hydrolysate Barriers
Sammanfattning : 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. LÄS MER
3. Suberin based polyesters
Sammanfattning : In the wish to replace oil-based chemicals and materials with such based on biodegradable and renewable resources, this work has been performed. In a biorefinary concept, waste birch bark from paper pulp mills and timber production has been evaluated as a potential source for polyesters. LÄS MER
4. Functional and Renewable Galactoglucomannan-based Hydrogels
Sammanfattning : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. LÄS MER
