With the growing global demand for renewable energy, oil palm waste (EFB, Empty Fruit Bunches) has gained increasing attention as a potential biomass energy source. EFB is the leftover material after oil extraction from palm fruit, typically containing 60–65% moisture and a loose fibrous structure. Untreated EFB is difficult to use directly and is often burned or dumped, causing environmental pollution.
Guide for EFB Pellet Plant Setup
Through EFB Pellet Mill and supporting processing equipment, these residues can be transformed into high-density, high-calorific EFB pellets, reducing moisture content to 8–12%, not only solving waste management issues but also facilitating storage, transportation, and combustion, providing a sustainable solution for industrial and energy supply. Choosing the right EFB pellet mill and EFB pellet plant is a key step for investors entering the biomass energy industry.
Composition of EFB and Its Application in Biomass Pellets
Oil palm empty fruit bunches (EFB) mainly consist of cellulose (30–40%), hemicellulose (20–25%), lignin (10–15%), small amounts of oil (2–5%), and minerals (1–3%). High cellulose and hemicellulose content provide a solid structural basis for pelletizing, while lignin acts as a natural binder during pellet compression, improving the density and durability of EFB pellets and reducing the need for chemical binders. Furthermore, EFB’s low ash content and combustibility make it an ideal biomass fuel for power generation, industrial boilers, and heat production.
After crushing, drying, and pelletizing, EFB moisture can be reduced to 8–12%, density is significantly increased, and calorific value reaches 4200–4900 kcal/kg, forming high-quality biomass pellets that are easy to store, transport, and burn.
| Component | Content Range | Function & Application |
|---|---|---|
| Moisture | 60–65% (undried) | Requires drying to reduce combustion and transportation losses |
| Cellulose | 30–40% | Provides pellet structure support, increases durability and density |
| Hemicellulose | 20–25% | Enhances pellet binding and calorific value |
| Lignin | 10–15% | Natural binder, improves pellet forming efficiency |
| Oil content | 2–5% | Increases calorific value, improves energy efficiency |
| Ash content | 1–3% | Low ash reduces boiler slagging and smoke emissions |
| Calorific value | 4200–4900 kcal/kg (after pelletizing) | High-energy fuel, suitable for power generation and industrial boilers |
In the EFB Pellet Mill production process, the composition of the raw material directly affects pellet density, durability, and combustion performance. High moisture requires efficient drying, cellulose and hemicellulose ratios affect pellet structure, and lignin content determines pellet compactness. Understanding EFB characteristics is crucial for equipment selection and optimizing EFB pellet production processes.

EFB Pellet Production Process
EFB pellets are high-density biomass fuel pellets formed through crushing, drying, and pellet compression. Typical pellets are 6–10 mm in diameter, adjustable in length, with a density of 600–650 kg/m³, and offer high and stable combustion efficiency. They can be used in industrial boilers, power plants, and regional energy supply systems.
The EFB pellet production process includes:
- Raw Material Preparation: Sort, remove impurities, and cut EFB to ensure uniformity.
- Crushing: Crush EFB to 3–5 mm for smooth compression in ring die pellet mills, improving pellet density and consistency.
- Drying: Use rotary dryers or fluidized bed dryers to reduce moisture to 8–12%, ensuring pellet forming quality.
- Pelletizing: Ring die pellet mills use lignin as a natural binder to form high-density EFB pellets with high durability.
- Cooling & Screening: Cool the pellets and screen out fines and broken pellets for uniform product quality.
- Packaging & Storage: Automatically pack pellets for easy transport and sale while ensuring long-term storage stability.

EFB Pellet Mill Selection Guide
Choosing the right EFB Pellet Mill is crucial for efficient production and high-quality pellets. EFB raw materials have high oil content, high moisture, strong hardness, and toughness, so the pellet mill must have sufficient compression power and wear resistance to ensure EFB pellets are dense, durable, and burn stably. Different production scales of EFB Pellet Plant require appropriate pellet mill models and supporting equipment to improve the efficiency of the efb pellet production line.
| Model | Capacity (kg/h) | Suitable Raw Material | Power (kW) | Dimension (mm) | Application |
|---|---|---|---|---|---|
| BPM42 | 1200–1500 / 1500–2000 | EFB, sawdust, stalks | 90+1.5+3 | 2600×1000×2000 | Small to medium-scale EFB Pellet Plant |
| BPM508 | 1500–1800 / 2000–2500 | EFB, coconut shell, bagasse, wood chips | 110+1.5+3 | 2990×1200×2410 | Medium to large-scale EFB Pellet Plant |

Considerations When Building an EFB Pellet Plant
When constructing an EFB Pellet Plant, clients need to focus on upfront investment and rapid return, including land, equipment, and maintenance costs. To achieve “cost reduction and efficiency improvement,” consider the following:
- Determine Production Scale: Plan capacity based on geographic conditions and market demand to avoid blind investment.
- Workshop Structure: Concrete workshops have low cost and good environment; steel workshops are faster to build and recyclable but more expensive.
- Production Process & Equipment: Choose experienced EFB Pellet Mill manufacturers and configure equipment reasonably to ensure output and product quality.
- Auxiliary Equipment: Proper design of fans, dust collectors, etc., ensures stable performance of the main equipment.
Workshop-Centered Plant Layout: Place raw material and finished product warehouses, boiler rooms, etc., around the main workshop to reduce labor and wiring losses. - Equipment Maintenance Management: Standard operation and preventive maintenance extend equipment life, improve efficiency, and reduce costs.
