Using palm oil mill effluent as organic fertiliser, Isuy Makmur Estate, West Kutai, East Kalimantan. Waste and effluent management (GRI 306) We implement strict waste and effluent management practices to improve efficiency, reduce costs and minimise environmental impact. All sites operate under systems compliant with Indonesian regulations and guided by PROPER and ISO 14001 standards (see page 70 in the Appendix for more details). Mills: In 2025, the average production of hazardous waste per mill was 1.10 tonnes (compared to 1.00 tonnes in 2024). Refineries: The total hazardous waste generated in 2025 was 22,570 tonnes (compared to 26,598 tonnes in 2024), with 84% attributed to spent bleaching earth. Additionally, non-hazardous waste totalled 1,766 tonnes in 2025 (compared to 2,155 tonnes in 2024), with 64% directed for recycling and the remaining 36% sent to landfill. Rubber Factories: The average production of hazardous waste per factory in 2025 was 0.56 tonnes (compared to 0.43 tonnes in 2024). In accordance with Ministerial Regulation No. 19 of 2021, which requires household waste to be sorted into organic, inorganic, and residual streams, we are now installing onsite waste sorting and temporary storage facilities at all workerliving sites. We have constructed appropriate spaces and are strengthening our interim waste management measures to ensure effective segregation and secure storage, even in the event of sporadic collection by municipal services. Milling waste is fully repurposed in our estates and mills as organic fertiliser or boiler fuel. This includes non-hazardous solids such as EFB), fibre and shells, In 2025, the total mass of milling waste reached 1,623,457 tonnes, up from 1,493,737 tonnes in 2024. Effluent from milling, known as POME, is a byproduct of processing FFB into CPO. Both solid waste and POME are managed under strict regulatory controls. Mill wastewater, including POME, is treated on-site. We compost POME in aerated bunker composters at three mills, which reduces GHG emissions. Mill effluent volume: In 2025, 1,995,105 m3 of wastewater was produced from our 27 mills, marking a 7% increase from 2024 (1,864,625m3). All effluent is treated to meet regulatory quality standards before being discharged into waterways or municipal sewer systems. Refinery effluent volume: 222,233 m3 of wastewater was produced in 2025 (2024: 294,688 m3). In collaboration with the government, we undertake annual effluent quality assessments to ensure we are within regulatory limits for BOD and COD. Mill effluent quality: At the 27 mills, the median Biological Oxygen Demand (BOD) was 642 (2024: 780 mg/l), and the median Chemical Oxygen Demand (COD) was 1,748 (2024: 1,960 mg/l). Refinery effluent quality: The median BOD was 10 (2024: 20 mg/l), and the median COD was 37 (2024: 50 mg/l). In 2025, we achieved zero spills (effluent, CPO, or diesel) during harvesting, processing, or transportation, incurred zero environmental fines or sanctions, and received no significant stakeholder complaints regarding the environment. Furthermore, 100% of all hazardous waste was legally disposed of via an accredited third-party, adhering to national regulations. 33 Indofood Agri Resources Ltd.
