Since 2009, our mills have started to invest in the latest technology for the treatment of Palm Oil Mill Effluents (POME).

A tertiary treatment plant was constructed at Retus Palm Oil Mill in Sarawak and commissioned in the fourth quarter of 2010. The treatment plant has the capability to reduce the Biochemical Oxygen Demand and Total Suspended Solids levels of the mill’s final discharge to meet the stipulated requirements set by the Sarawak Department of Energy (<20mg/L BOD and <100mg/L TSS). Similar treatment plants are being constructed at the Trusan Palm Oil Mill and Binu Palm Oil Mill, both located in the state of Sarawak.

In order to reduce green-house gas emissions, we are currently evaluating the various technologies available for methane capture, with a view of utilising the captured gas for energy generation. Methane (CH4) is one of the major green-house gases produced in the anaerobic treatment of POME.
