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. Development towards an efficient and sustainable biofuel drying
Sammanfattning : The usage of biofuel as well as wood fuel has increased in Sweden and all of Europe during recent decades, and there are several reasons to believe that this increase will continue. An important reason for this increase is that the environmental and climate problems caused by fossil fuels are becoming even more evident. LÄS MER
3. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry
Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER
4. Wood Fuel Pellets: Sawdust Drying in the Energy System
Sammanfattning : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.

5. Improving Wood Fuel Pellets for Household Use : Perspectives on Quality, Efficiency and Environment
Sammanfattning : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. LÄS MER
