Minimising Net Greenhouse Gas (GHG) Emissions
Palm Oil mills produce a liquid waste known as Palm Oil Effluent (POME) - a brownish coloured liquid discharge that contains inorganic and organic solids, a small amount of Palm Oil and water.
POME is usually treated using a process of Anaerobic digestion in deep open lagoons, with reduced toxicity thereafter. Methane gas is generated during the Anaerobic digestion of Palm Oil Mill Effluent (POME), and is 34 times more potent that carbon dioxide (CO²).
We are committed to operating in a manner that minimises net GHG emissions, towards a goal of low carbon emissions.
Our methane capture system solves this issue by capturing the methane gas generated by the POME. The lagoon is tightly sealed with a High Density Polyethylene (HDPE) so that the methane gas is not released into the atmosphere.
The captured methane gas is subsequently harnessed as fuel to generate electricity for use in the mill and estates, workers' housing as well as to local communities. All of the group's mills are now fitted with a methane capture system.
To-date, we have 15 POME-biogas plants are in operations. We are the first major group in the industry to commit to extending this initiative to all our mills since 2010.
By capturing and using this gas, approximately the group total CO² emission saving is equivalent to 750,000 tonnes per annum. This is equivalent to the amount of carbon emitted by 163,000 cars in one year.

The Roundtable on Sustainable Palm Oil also has a collection of case studies, one of which also features our work. You can download the publication here.
We were also mentioned by Daemeter Consulting, an independent consultancy firm promoting sustainable development. The case study can be viewed here.
