The company utilizes Palm Oil Mill Effluent (POME) because it contains essential nutrients for plant growth and production, such as N, P, K, Ca, and Mg, in significant concentrations. Therefore, POME with a certain Biological Oxygen Demand (BOD) can be used as a substitute or supplement for fertilizers and irrigation water in mature palm oil plantations. This utilization of POME is known as Land Application. All of the company’s palm oil mills have implemented this Land Application method, which complies with the quality standards required by applicable regulations. We mandate that all palm oil processing facilities have open ponds for treating POME. In these ponds, POME undergoes special treatment until it meets the pollutant content standards set by the government. The treated POME is then used as liquid fertilizer applied to plantation areas. This aligns with our environmental management policy to maximize the implementation of clean technology or clean production, aiming for zero emissions and adopting the 3R (Reuse, Recycle, and Recovery) concept in waste management to mitigate negative environmental impacts.
We also utilize surface water from rivers or streams within the plantation for production processes at the palm oil plantation and mill. Water needed for processing at the mill comes from surface water, which is channeled into reservoirs for storage and then used as required. To ensure the sustainability of surface water supply, the company maintains water catchment areas and sources by preserving riparian zones, implementing terracing on hilly areas, and planting legumes to maintain soil moisture.
Solid waste generated from palm oil plantation processes, such as fibers, shells, and empty bunches, is reused in various ways, including as fuel and fertilizer. By utilizing this solid waste as a resource, the company reduces waste production and supports sustainable practices.
