Photographic record Organic Fertilizer / Compost production

PT Rebinmas Jaya, Indonesia.

Key Stats:

1. Compost plant capacity: 1,300mt / mth.

2. Consistently saving at least 30% of compound fertilizer input dosage (vs. conventional manuring programme).

3. 100% EFB run through LB EFB Preparation System: 40% for compost, 30-40% for boiler fuel, remainder mulching nearby. This lead to reduced usage of PKS in boiler.

4. EFB liquor sent for oil recovery – significantly higher oil recovery than conventional system.

5. No environmental issue on POME discharge: water goes through conventional POME Pond system. Sludge removed earlier, POME to maintain WIP compost moisture level.

6. Economically Sustainable:

  • EFB Oil Recovery (avg +0.8% OER)
  • Reduction in Inorganic Fertilizer Input (-30%)
  • Increase PKS recovery (6%)
  • Reduction of POME discharge
  • Returning of biomass wastes back to the soil in a stable and matured condition, ensuring soil health is maintained.
Fresh EFB from the trasher to the EFB Preparation System
EFB Pulveriser: Shredding EFB by tearing them apart.
Shredded EFB channeled into a press to extract excess liquor for oil recovery.
EFB shredded down to 2-4 inches length, increasing the surface area of compost material.
Liquor from EFB: approx. 10-12% is oil. Depending on mill’s efficiency and design, oil loss varies from mill to mill.
Palm Oil Mill Wastes Raw Materials: Empty Fruit Bunches (EFB)
Palm Oil Mill Wastes Raw Materials: Boiler Ash
Palm Oil Mill Wastes Raw Materials: Decanter Cake
Palm Oil Mill Wastes Raw Materials: Palm Oil Mill Effluent (POME) Slurry
Raw materials are mixed together following a desired ratio, microbes cocktails (inoculant) are also added to accelerate decomposition.
Maxed materials arrange info window to start the composting process.
Lead time: 45 days
Compost is packed into 20kg bags and delivered to the estate.
Application of compost: 20kg / palm / yr.
