POME Oil (Palm Oil Mill Effluent Bio-Oil)
Industrial Wastewater Bio-Lipid Recovery for Advanced Biofuels & Biogas Feedstock
Palm Oil Mill Effluent (POME) Oil is a high-value industrial bio-oil recovered from the treatment ponds of crude palm oil extraction mills. It serves as an advanced, non-crop second-generation feedstock for renewable diesel and biochemical production.
About POME Oil (Palm Oil Mill Effluent Bio-Oil)
During the wet milling of fresh palm fruit bunches, substantial quantities of process water and wastewater are generated. Traditionally treated in anaerobic stabilization lagoons, modern palm mills employ skimmers, centrifuges, and recovery systems to capture the residual floating lipid layer known as POME Oil or Sludge Palm Oil. Because it originates from mill wastewater without competing with food crops or arable land, POME Oil qualifies as an advanced low-ILUC (Indirect Land Use Change) bio-feedstock under international renewable energy frameworks. United Saud Malaysia coordinates the commercial supply of recovered POME oil to industrial off-takers.

Shipment & Transit Considerations
- Non-Food Classification: Explicitly designated as waste residue under maritime hazardous/non-hazardous classification. Prohibited from any food or animal feed applications.
- Viscosity & Temperature: Because POME Oil contains high levels of saturated free fatty acids, it solidifies at temperatures below ~40°C. Flexitanks must be connected to heating coils/pads at destination prior to discharge.
- Inspection: Pre-loading sampling by independent marine surveyors to ensure compliance with agreed TFM, FFA, and M&I tolerances.
Export Quality & Shipping Dossier
- Independent Marine Surveyor Certificate (SGS, CCIC, or equivalent)
- Mill Origin Declaration (verifying genuine effluent recovery source)
- Safety Data Sheet (SDS) for Industrial POME Oil
- Export Customs Declaration (Malaysian Customs Department)
- Commercial Clean on Board Ocean Bill of Lading
Frequently Asked Questions: POME Oil (Palm Oil Mill Effluent Bio-Oil)
How is POME Oil recovered from palm mills?
Palm Oil Mill Effluent (POME) is the liquid byproduct discharged during the sterilization, clarification, and purification stages of fresh fruit bunch processing. Before the effluent enters anaerobic treatment lagoons, residual oil that floats to the surface is recovered using oil traps, disc-stack centrifuges, or dissolved air flotation (DAF) systems.
Why is POME Oil favored by renewable fuel refiners?
Because it is derived from industrial wastewater without utilizing additional arable land or competing with the human food chain, it qualifies as an advanced, high-GHG-saving feedstock under European (RED II/III Annex IX-A) and international low-carbon fuel standards.
