Waste Management

Effluent Management

Palm oil Mill Effluent (POME) is the primary organic waste output from the production of palm oil. Discharging untreated effluent into water streams is strictly illegal and may cause considerable environmental problems – and adversely affect life underwater.

We maintain robust management systems to ensure all our mills and refinery operations are equipped with Palm Oil Mill Effluent Treatment Systems (POMETS) and Industrial Effluent Treatment Systems (IETS) that support the management of waste and comply with national environmental standards. We have also invested in training our employees to manage effluent and their treatment systems.

Composts can be produced through a combination of the two largest constituents of mill wastes, POME and Empty Fruit Bunch (EFB), as well as other by-products, namely decanter cake and boiler ash. Composts are applied in estates as soil conditioner to ameliorate estates’ soil. Sime Darby Plantation (SDP) began composting as part of its mill waste management in 2004.
