Waste management in all Merdeka mining operations is carried out so as not to pollute the air, soil, and water by continuing to comply with the management procedures in the Environmental Management Plan (RPL) and Environmental Monitoring Plan (RKL).

Merdeka is actively implementing the 3R (reduce, reuse, recycle) campaign. All residual waste is identified, sorted, measured and destroyed, or utilized following regulations. The destruction and utilization of waste are carried out in cooperation with a licensed third party.

Waste management is part of the Environmental Impact Analysis (AMDAL) document, including the Environmental Management Plan (RKL) and Environmental Monitoring Plan (RPL) of each Merdeka mining operation, which has been approved by the government.

Hazardous and Toxic Waste (B3) at the Tujuh Bukit Gold Mine and Wetar Copper Mine is managed by sending it to a licensed third party. The two Merdeka mining operations send their used oil to the same processing company and recycle 50-65% of B3 waste into diesel and fuel oil.

All hazardous toxic waste (B3) from the Tujuh Bukit Gold Mine is sent to a B3 waste processing and utilization facility that has a destruction and utilization permit. By 2021, 954 tonnes of LB3 were managed according to government regulations, without incident.

Meanwhile, non-hazardous waste, including domestic waste, is managed through the 3R (reuse, reduce, recycle) program. Food waste is managed by the community around the mine for animal feed. Recycling of inorganic waste that has economic value is carried out by local businesses assisted by the company. The rest of the non-hazardous waste in the form of domestic waste is sent to the Final Disposal Site managed by the Banyuwangi Regency Government.

There is no significant impact on the environment due to the hydrocarbon spill in 2021 in the Tujuh Bukit Gold Mine area. Any spills can be handled immediately and soil contaminated with spills is immediately collected and managed as B3 waste.

All hazardous and toxic (B3) waste generated at the Wetar Copper Mine sent to a licensed B3 waste processing and utilization facility. In 2021, the BKP-BTR operation has sent 888 tons of waste.

Several significant spills occurred in 2021. These spills were immediately contained, neutralized, and remedied, without causing any impact on the surrounding environment. The incident has been investigated and resulted in recommendations for prevention.
