1. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard
Sammanfattning : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

2. Hemicellulose-based wood adhesives
Sammanfattning : The increasing sustainability concern encourages the society to use sustainable resources. In the wood industry the main component is from a renewable resource, but others are not. One of the fossil-based components is the adhesive. LÄS MER
3. Polysaccharide-based wood adhesives
Sammanfattning : It is highly desirable to increase the use of renewable resources and reduce fossil-dependence due to sustainability concerns. As a consequence, it is expected that the use of the wood-based materials will increase in the future. Therefore, adhesives will have an important role since they allow for the use of lower-quality and recycled wood. LÄS MER
4. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation
Sammanfattning : Surface densification of a piece of solid wood results in an increase in density and in hardness in the whole or a part of the densified material, and is one of the ways of improving the properties and value of low-density wood species. Despite efforts for many years, mass commercialisation of either bulk- or surface-densified wood products has not yet been achieved. LÄS MER
5. Acetylation of Solid Wood. Wood Properties and Process Development
Sammanfattning : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.
