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.
