Chemical and Pest Management

We are committed to use composting as much as possible and reduce the use of inorganic fertilizers. Composting is not only much a cheaper source of natural fertilizer compared to inorganic fertilizers, but also a much more environmentally friendly alternative with less emissions of GHG. Current composting technology will only allow us to produce compost that are adequate to be applied to a maximum of half of our plantation area.

We target each estate to have its own composting processing plant by 2030 and reduce inorganic fertilizer use by 30% compared to the 2015 base year. Currently, two of our estates, ANJAS in North Sumatra and SMM in Belitung, have their own composting plants, producing 76,562 tons of compost in 2021. This was sufficient to be applied to 51% of our area to improve the soil nutrient condition. We plan to build another composting plant at KAL in West Kalimantan. In concessions with no composting plants, we recycle empty fruit bunches to reduce inorganic fertilizer use. In 2021, we used a total of 206,733 tons of organic fertilizers, or 87% of the total fertilizers used.

Inorganic fertilizer usage in the last 6 years within our Group is as follows:

We are also committed to reduce chemical usage for pest & disease control. Our Research and Development department tried to develop biological predators and biological insecticides for pest management. This is part of our effort to implement best and sustainable agronomic practice to control pests and diseases. We use Tyto Alba barn owl to reduce rat attacks, which was successful to reduce intensity of attacks from 9.8 % to 1.7%. We also use biological insecticides, such as Bacillus thuringiensis and Metarrhizium anisopliae as part of our Integrated Pest Management program. The list of chemicals used in our palm oil plantation is as follows:
