WATER, EFFLUENTS AND SPILLS
WATER RESOURCES
Water is a critical resource for both the plantations and the people living on the estates. Our plantations are generally watered by
rainfall. 95% of the water required by the factories to process the FFB is drawn from nearby rivers, with the remaining needs are met
by groundwater supplies.
Water for domestic usage is drawn from groundwater in several areas. We construct dams and wells to ensure a steady supply of water
for the people. In Riau, South Sumatra, North Sumatra, Java, Sulawesi and Kalimantan, we have also installed 80 water treatment
facilities to provide water for our employees.
We strive towards reducing our water footprint per tonne of FFB processed.
The refinery utilises a waste water treatment plant before releasing its waste water. In 2013 our Biological Oxygen Demand (BOD)
levels were well below the maximum level of 30 mg/L.
In the Pluit refinery we achieved a strong reduction in BOD levels
in 2012 and 2013 through the installation of a new carbon filter.
UTILISATION OF POME
Palm Oil Mill Effluents (POME) have been used as organic fertilisers
since 1992. POME is collected in anaerobic open ponds on our
estates for treatment and to maintain a moderate BOD level to
retain nutrients in the effluents. Our teams check and adjust the
condition in the ponds every month to maintain the BOD level
within the legal limit of 5,000 ppm for effluent land application.
Maximum care and supervision are carried out to ensure that
no effluent would enter the river as surface run-off at all times.
PREVENTION OF SPILLS
To prevent CPO or diesel spi l lage during production and
transportation, we set stringent procedures on the transport of
CPO from the factories and storage tanks.
