Waste management

We have implemented systems to measure and dispose of the waste we produce in a responsible manner, and in line with regulation. Our refineries generate scheduled waste and non-scheduled waste. All waste classified as scheduled may possess hazardous characteristics with potential to have adverse effects on public health and the environment. Therefore, handling of scheduled waste requires special storage, packaging, labelling and management of containers.

Waste generated and disposal methods
Types of waste Source Disposal method
Scheduled Used cotton rags, residual glycerine, lubricants, used oil, air filters and empty chemical containers All scheduled and non-scheduled waste is disposed through licensed contractors approved by respective national authorities, and verified by government bodies.
Non-scheduled Spent bleaching earth from degumming and bleaching CPO and sludge from wastewater treatment plants
Palm oil refinery effluent (PORE)

Palm oil refinery effluent (PORE) is a type of wastewater produced by the refining of the crude palm oil (CPO). PORE has high contents of biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, total suspended solids, oil, phosphate and ammonia, which can be harmful to the environment and aquatic ecosystems if left untreated.

We ensure all PORE is treated using both biological and chemical processes to maintain levels within regulatory thresholds before being discharged to waterways. The treatment process involves aeration, coagulation, and filtration through carbon and sand before the clean water is discharged out. Palmindo, Pamin and Oleochem are situated within one industrial site, and therefore all the treated water is discharged to Kawasan Industri Medan (KIM) before being channelled to nearby waterbodies. The PORE treatment processes at our Indonesian sites are all externally verified by the relevant Indonesian body and assured by independent laboratories. PACOIL’s treatment process is verified by our annual certification audits as well as the Malaysian Ministry of Health.
