Our nickel mining and processing activities generate some waste. In accordance with good mining practices or good mining practices, we are committed to comprehensive and sustainable environmental management.
In waste management, we have implemented the framework of the International Council of Mining and Metals (ICMM). Meanwhile, in 2021 we set five environmental commitments to support the achievement of zero carbon emissions, a low carbon agenda, reducing landfill burdens, reducing the intensity of water consumption, transboundary forestation, and biodiversity conservation.
The waste management policy covers B3 waste management, which includes oil, used grease, filters, rags, expired chemicals, used batteries, used batteries, paint, asbestos, and medical waste. Meanwhile, we manage non-B3 waste, including topsoil, overburden, and household waste.
Hazardous and Toxic Waste Management
We have a Hazardous and Toxic Waste Reduction and Utilization Policy. Our commitment to reduce the generation of hazardous and toxic waste or B3 by 50 tons/year and utilize B3 waste by 1,000 tons/year is realized through:
Use Kidney Lube and Modular Screening Station to reduce the generation of B3 waste by using hydraulic lubricating oil, rags, batteries, and oil filters.
Purchase using Iso Tank to reduce the generation of B3 waste using used drums.
Utilization of used oil for HSFO fuel substitution.
The company also has a Non-Hazardous and Non-Toxic Waste Reduction and Utilization Policy. Our commitment is to reduce the generation of non-B3 waste from domestic waste by 300 tons/year and utilize non-B3 waste by 4,100,000 tons/year through:
Using ECOTERAKO green aggregate from nickel slag as the material of choice for mine road construction.
Road material recycling uses road stabilizer equipment to conserve road materials.
Using chipping stone material from the waste reject station as a substitute for top layer crushed stone (LPA) material on logistics roads.

The construction of this facility is a form of the company's compliance with the Regulation of the Minister of the Environment No. 9 of 2006 concerning Wastewater Quality Standards for Nickel Ore Mining Business and/or Activities.
LGS technology is commonly used for drinking water treatment, and PT Vale Indonesia is the first to use it in the mining industry in Indonesia. Liquid waste treatment is accompanied by regularly checking lake water quality with independent institutions. The results of measurements of TSS and Cr6+ levels in Lake Matano and Lake Mahalona are consistently far below the quality standards of the government and APHA.
Periodically we report on performance and environmental issues regularly since the commencement of operations through reports on the Environmental Management Plan/Environmental Monitoring Plan (RKL-RPL), KLHK Electronic Reporting Information System (SIMPEL-KLHK), and reclamation reports according to the established timeline. In regulations (monthly, quarterly, semester and yearly). To ensure that environmental management and monitoring are carried out properly, the Environment Committee conducts a monthly performance evaluation, whose members consist of Senior Managers and Directors.
We continue to create environmental awareness for all employees, such as conducting housekeeping competitions, waste management campaigns, General Induction Program (GIP) training for all new employees and visitors, and commemorating World Environment Day. In addition, the Company provides several trainings on environmental awareness such as “TNA, training schedule and certificate and absenteeism.
