From Empty Friut Bunches into Biomass PelletsAs we know, Pellets can be made of sawdust and shavings and agircultural waste such as rice husk and wheat straw. However, Empty fruit bunches(EFB) can be put into use for pelletization as well. Over the past decades, forest materials have been used in a wider range while the EFB material seems like an untapped resource for pelletization. Actually in the wake of development of renewable energy, the higher requirement for expansion of feedstock application for pelletization is also put forward. Comparing with wood material, EFB material possesses also the features of cost efficiency and sustainability, not least for industrial grade pellets destined for heat and power.

The palm oil industry of Southeast Asia boasts the largest and richest resources around the globe, representing a huge amount of unutilised raw material for pelletization. Across the whole Malaysia alone there are more than 400 crude palm oil mills. However, the EFB from the industrial sector has still not yet been tapped into and readily available for pellet making.
There is no denying that EFBs due to the loose and voluminous with a fibreous and stringy structure are tough to be handled in some procedures of pelletization such as cutting, shredding, pelletizing and drying. Thanks to the R&D of EFB pelletization, the material can be used. For instance, an EFB pellet production line may consists of three units, pretreating section for size and moisture reduction to produce 20mm fine fibers at 20-25% MC, pelletizing unit and cooling and packaging unit. At the stage of cleaning, a lot of solid content can be separated from fibers so that the solid will consist mainly of parenchyma and fine fibers which happen to be suitable for pellet production.
