Biological controls against pests:

Beneficial plants such as Turnera Subulata, Antigonan Leptopus and Casia Cobanensis 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. During

the year, the Group commenced an environmental impact assessment (“EIA”) on its greenfield development in Sungai Siput,

Perak. The EIA is still on-going and is expected to be completed this current financial year.

Waste Management

The

Plantation Division

adheres to a “zero discharge” policy by recycling waste and by-products. At our palm oil mill in Indonesia,

the primary oil mill waste comprises of POME generated mainly from oil extraction and EFB. These are both utilised in various

ways:

POME discharged from the mill must not be reintroduced into the environment in its raw form. Raw POME has a high acid content

and, due to its rich nutrient content, the Biological Oxygen Demand (“BOD”) level is high too. However, our average BOD reading

for POME during the land application stage falls well within the allowable discharge limits of <5,000 parts per million (“ppm”).

The POME collected from the mill is treated in open ponds located on site. The organic material in wastewater is broken down

by natural occurrences of anaerobic and aerobic bacteria. This process eliminates the need to add chemicals before the water is

discharged and results in successful fish breeding at the final effluent pond. POME is utilised in two ways, it is either mixed with

shredded EFB to make our compost or applied directly to estate using the furrow system.

In addition to being converted into compost, shredded EFB is also widely used as feedstock for the steam boiler at the mill for

power generation.

Further, we regularly monitor the POME used for land application to ensure that it does not overflow into the natural waterways.

PTNJL has achieved the Green rating, the second highest level in Indonesia’s Program for Pollution Control, Evaluation, and

Rating (PROPER) in the manufacturing/agroindustry category for 4 consecutive years. The Green rating is awarded to businesses/

activities that have displayed environmental management effort and achieved results better than those required by regulation.

Hazardous waste and residual products recovered from our operations are disposed of in accordance with stringent industry

standards and statutory requirements.
