Increased resource efficiency through innovative new raw material handling in the production of fuel pellets
The overall goal of the project is to generate new knowledge and support for:
- Separation of sawdust from small timber and coarse timber. Small timber sawdust contain a high proportion of sapwood and coarse timber sawdust contain a high proportion of heartwood, which have different properties for pellet production.
- Evaluate drying techniques in combination with the impact of the different sawdust fractions on pellet quality and storage properties.
- Develop rapid spectroscopic methods to assess the quality of the raw material for pelleting and for process control.
The project is in collaboration between SLU, Karlstad University (KaU) and The Paper Province. SLU is responsible for overall project coordination.
