Wood pellets are skewer shaped and pressed fuels out of wood. They get fired in special pellet heating systems.

Production:

The pellets are getting produced in pellet facilities. The material is getting pressed trough a steel matrix under high pressure. It merges without any binding material through the wood own lignin. For supporting this process you can throw in some binding material like thickness or molasses in a small amount (e.g. 0,2 - 2%). If the matrix exits, the strands can be cut in the wanted length.
