The pellets are cooled, which hardens them for storage and transport, and then packaged for distribution.

The choice of raw materials affects each stage of the biomass pellets manufacturing process, from pre-treatment to final pellet quality.

Impact of Different Raw Materials on the Biomass Pellets Manufacturing Process

Wood-Based Biomass

Wood is one of the many commonly used raw materials in the biomass pellets manufacturing process. It includes sources like sawdust, wood chips, and forest residues. The advantages of wood-based biomass are its availability and relatively high energy content. Additionally, wood-based biomass typically has a lower ash content, which makes the resulting pellets more efficient and cleaner during combustion.

However, the biomass pellets manufacturing process involving wood also presents some challenges. Wood needs to be dried thoroughly before pelletizing, as excessive moisture can hinder the pellet mill’s performance. Moreover, hardwoods and softwoods behave differently during compression, meaning that the type of wood used can impact the efficiency and quality of the pelletizing stage.
