The energetic use of Empty Fruit Bunches (EFB) offers significant potential, but it also comes with technical challenges. High moisture content, contamination during harvesting, and alkaline ash components have long made EFB difficult to process reliably at industrial scale. EFB Green Energy has developed a proven, industrially viable solution that overcomes these challenges and enables stable, continuous pellet production.
Key Benefits at a Glance
- Industrial Reliability
Stable, continuous pellet production designed for 24/7 industrial operation. - Cleaner Combustion
Reduced slagging, fouling, and corrosion through effective removal of alkaline components. - High-Quality Pellets
Consistent pellet quality suitable for demanding industrial combustion systems. - Energy Self-Sufficiency
On-site utilization of residual oil (POME) significantly reduces external energy demand. - Low Water Consumption
Closed-loop washing system minimizes fresh water use and wastewater generation. - Reduced Maintenance & Downtime
Early contamination control protects equipment and lowers wear on critical components. - Circular Economy Impact
Waste streams are converted into valuable energy, with recovered potassium reused as fertilizer. - Scalable & Replicable
Modular process design enables straightforward expansion and replication at additional sites.
A key advantage begins right at the source. EFB is taken directly from the palm oil mill and fed into the process without intermediate storage. This minimizes contamination from stones or sand and protects downstream equipment. As a result, wear on cutting tools is reduced, reliability is increased, and unplanned downtime is largely avoided.
After size reduction, residual oil contained in the biomass is mechanically extracted using a dedicated screw press. This by-product (POME) is used for on-site energy generation and forms the basis of a largely self-sufficient energy supply for the plant. The outcome is lower external energy demand and a more stable, cost-efficient operation.
At the heart of the process is EFB Green Energy’s proprietary multi-stage alkali washing system. This step selectively removes alkaline components, particularly potassium, which significantly increases the ash melting point of the pellets. The result is a cleaner-burning fuel that reduces deposits, slagging, and corrosion in industrial combustion systems—an essential requirement for reliable, long-term customer use.
The washing system operates as a closed loop, with wash water continuously treated and reused. This keeps fresh water consumption and wastewater volumes low, while the recovered potassium can be reused as fertilizer, further supporting the circular economy.
The final pelletization step uses pellet presses specifically designed for EFB, combining high throughput with low maintenance requirements. Together, these process steps ensure consistently high pellet quality, stable production, and excellent scalability—making EFB Green Energy’s solution well suited for industrial customers and long-term expansion.
