Palm kernel shell is the shell of palm fruit (Arecaceae), being separated from palm fruit throng palm oil process. It is known as a common kind of biomass waste or residue from palm oil industry. It is also named as PKS or oil palm EFB. Before biomass pellets enter the world market, palm kernel shells are generally be used to make black color palm kernel compost by burying underneath the land for a very long time. With the develop of biomass fuel and pelleting technology, palm kernel shell is becoming hot in pellet making industry in recent years due to its high calorific and cheap recycle price, especially in European countries and Southeast Asia. In Malaysia, because of rich palm resources, palm kernel shell is their first choice of biomass pelleting.

Palm fiber pellets or briquettes are compressed palm fiber. They are made by pellet mill and briquette machine.

Some people may wonder that why not burn the shells or palm fiber directly in the boilers? Below is the reason of making palm kernel shell pellets.
This is one of our projects of PKS pellet production line. It is built in Serbia. Below is the basic information of this pelletizing project.
Palm Kernel Shell or PKS is ideal materials for making fuel pellets, but it is also relatively more difficult to be pelletizer than wood materials such as sawdust or wood chips. Therefore, you need a professional pellet plant manufacture. Because of rigid gear transmission system and structural design, the industrial ring die type pelletizer of ABC Machinery has outstanding performance in making palm kernel shell pellets.
