POME-derived Oil is the recoverable fatty fraction separated from palm oil mill effluent (POME) — the wastewater generated when crude palm oil is extracted from the fruit. Green Star Bio brokers this recovered oil as a cost-effective renewable feedstock for biodiesel and HVO producers.
With higher free fatty acid and moisture than UCO, it suits processors equipped for pre-treatment. We match grade, volume and logistics to your plant and confirm specifications per shipment.
When we broker this product, our desk monitors the parameters below to match grade to your process, destination and sustainability needs.
| Free Fatty Acid (FFA) | ≤ 30% |
|---|---|
| Moisture | ≤ 2.0% |
| Impurities | ≤ 0.5% |
| Density (20°C) | 0.89 – 0.92 g/cm³ |
| Saponification value | 190 – 205 mg KOH/g |
Specification values shown are typical reference ranges. Contract specifications are confirmed per shipment and may differ by origin and grade.
A biodiesel plant needs a lower-cost feedstock to blend with UCO and wants POME oil at agreed FFA and moisture, delivered in bulk.
A palm mill with recovered POME oil capacity seeks off-takers able to handle higher-FFA feedstock on recurring terms.

POME-derived oil is the oil recovered from palm oil mill effluent after separation. Once filtered, de-watered and assayed it becomes a tradeable commodity in its own right, sitting in the feedstock slate between used cooking oil and crude palm oil in both price and quality.
The value proposition is straightforward: it is waste-derived, so it qualifies for the incentives and double counting that virgin palm oil does not, and it is cheaper than UCO. The constraint is consistency. Because recovery practice varies from mill to mill, free fatty acid, moisture and solids vary more widely than buyers would like, and the difference between a well-run recovery operation and a poor one shows up directly in the assay.
In practice most offtakers handle it in one of three ways: pretreatment at or near the mill to bring FFA down before shipment, blending into a mixed feedstock slate at the refinery, or purchasing on a specification band with an explicit price adjustment mechanism for off-spec parcels.
Usually in stages: primary skimming or settling of the free oil from the effluent, then secondary recovery with a centrifuge or dissolved air flotation, and finally filtration and de-watering before storage. Mills with modern recovery plants get substantially higher yields and lower FFA than those relying on simple skimming.
Recovery rates vary widely with mill practice. A well-run plant can recover a meaningful fraction of a percent of the effluent volume as oil, which across a large milling operation adds up to a commercially significant annual tonnage. Yield, not price, is usually the biggest lever on the economics.
It is cheaper but dirtier: generally higher free fatty acid, more moisture and more solids. A refinery with pretreatment capacity can run it profitably; one without will prefer UCO. Many converters run both, using UCO to smooth the specification of a POME-containing slate.
As a waste and residue feedstock it can qualify under the Renewable Energy Directive and count double toward transport targets, subject to meeting the sustainability and greenhouse gas saving criteria and to documented chain of custody through ISCC or an equivalent recognised scheme.
In bulk by ISO tank, flexitank or road tanker for regional movement, and by vessel for export. Because moisture and solids settle in storage, parcels are normally assayed at both load and discharge and the contract specifies which assay governs.
