It is a common practice to convert Empty Fruit Bunch (EFB) into dried long fibers (DLF), fertilizers, corrosion-control mattress, packaging materials, and biomass pellets. In particular, biomass pellet has obtained high demands from the countries like Korea and Japan due to the environmental policies. The main application of EFB pellet is as a renewable fuel in industrial boilers and power plants. Most noteworthy, the conversion from raw material into pellets is a complex process. Therefore, the whole pellet production process requires an in-depth industry specific know-how.
EFB is a biomass by-product from the palm oil industry upstream activities. Thus, it is available in great abundance throughout the year. In Indonesia, EFB is known as “tandan kosong sawit” or “tankos”. In 2017, Malaysia had produced approximately 23 million tonnes of EFB. On the other hand, Thailand had produced approximately 2.5 million tonnes of EFB in the year of 2012. Furthermore, Indonesia had produced approximately 31 million tonnes of EFB in 2015.
Properties of EFB
Depending on the end-user’s requirements, EFB pellet plants may have different designs. The pressed and shredded EFB fiber which has the length of 2 to 4 inch and 50% of moisture content will be the pellet’s raw material. Typically, EFB pellet has the ash content of 2% to 7% and the moisture content of 10% to 12%. The main factors that can affect the pellet quality are: pellet mill design, equipment operational settings, material handling, physical and chemical qualities of EFB from the upstream process. Meanwhile, the advanced technologies such as torrefaction, steam explosion, and other proprietary technologies can further refine the pellet quality.
A good pellet production system should be operating at minimum interruption with consistent pellet output and quality. Therefore, it is vital to maximize the production up-time which relies heavily on the experience of EFB material preparation. Therefore, through our internal R&D initiatives and our biomass project engineering experience, we have designed and built EFB pellet plants which are able to meet the client’s specific requirements.
