Waste Management
The Plantation Division adheres to a “zero waste” policy by
recycling waste and by-products. At our palm oil mill in Indonesia,
oil mill wastes comprising POME and EFB are converted into
organic fertilizer or compost which is then applied directly to oil
palm fields as a source of nutrients and to supplement fertilizer
application. We monitor and treat all effluent and wastewater
before discharging into the effluent pond. The organic materials in
the wastewater are broken down by natural activities of anaerobic
and aerobic bacteria. This process eliminates the need to add
chemicals before the water is discharged and this had resulted in
successful fish breeding at the final effluent pond.

Biological controls against pests:
Beneficial plants are planted to
attract predators (insects) of leaf pests. These predators feed on
leaf pest larvae thereby minimising the usage of pesticides. The
introduction of barn owls in estates to suppress rodent population
and the placement of pheromone traps to capture Rhinoceros
beetles are among methods that have been adopted and proven
effective.
Environmental assessment
: Environmental impact assessments
are carried out ahead of any new plantation development.
PTNJL has applied 17,671 tonnes or 44% of
total EFB produced to the fields to allow for
the slow release of organic nutrients through
decomposition while conserving soil moisture
and improving soil structure. The remaining
56% or 22,660 tonnes of EFB were processed
into compost for application to the fields as
well as biomass fuel for the boiler.
