Key measures include: Packaging and Labelling All B3 waste is securely contained using rust-resistant, non-reactive packaging materials designed to prevent leakage and to meet the requirements set by the Environmental Impact Management Agency. Special Handling for Explosives Explosive waste is stored in pressure-resistant, double-layered containers to ensure secure and safe containment. Dedicated Storage Facilities B3 waste is stored in waterproof, corrosion-resistant, and fire-resistant facilities that are equipped with adequate ventilation. Trained Personnel Employees responsible for handling B3 waste hold relevant certifications, including PLB3 (Person Responsible for Hazardous Waste Management) and OPLB3 (Hazardous Waste Processing Operations). Monitoring via Sistem Pelaporan dan Evaluasi Digital (SPEED) The Electronic Manifestation Application (SPEED) is used to monitor B3 waste operations, ensuring regulatory compliance and preventing improper disposal. Our operations team actively works to minimise the generation of hazardous waste by optimising processes, substituting raw materials, and adjusting operational procedures. Non-Hazardous Waste We work closely with mining contractors to minimise non-hazardous waste. Initiatives include implementing a centralised collection system for non-hazardous waste generated at o"ce and dormitory facilities, where waste is collected daily and transported to government-designated Final Disposal Sites (FDS). Performance and Initiatives In 2025, 565 tonnes of hazardous waste were generated from SDJ, TBR and TRA sites, representing an decrease compared to the previous year. The inorganic waste from mine sites constitutes a substantial portion of non-hazardous waste was added to the reporting boundary in 2025. No hazardous waste was disposed of in public bins or exported overseas. Throughout the reporting period, we recorded zero incidents of non-compliance with waste management regulations and incurred zero significant fines. Continuous Improvement To further reduce our environmental impact from waste, we will: • Maintain full compliance with all applicable local waste management laws and regulations. • Introduce additional measures to minimise waste generation, including assessing and adopting innovative solutions. • Continue collaborating with reputable and accredited waste management service providers. • Enforce strict safety procedures for the storage and handling of hazardous waste.
