The Company upholds responsibility for the environmental impact of tin mining activities as mined areas can affect water availability levels. On the other hand, our operational activities require water so we implement water treatment practices, consume water wisely, and run water conservation programs.
Interaction with Water Sources and Water Consumption [303-1, 303-3, 303- 5]
The Company uses water for several purposes including in tin ore mining activities, spraying transportation areas to reduce dust, and for domestic needs, both at operational sites and offices. The source of water used in the production process comes from various sources such as rivers, groundwater, and rainwater.
We manage the availability of water and ecosystems around the mining area and protect water sources. We do not yet have a Water Intake Permit (SIPA) and reuse water from sediment ponds (in the process of licensing to the Ministry of Public Works and Housing (Kementerian PUPR). We have not identified water withdrawal areas that are experiencing water stress. However, we effectively withdraw water from the source and fulfill the requirement of being below the predetermined usage limit. Muntok Metallurgical Unit and Kundur Metallurgical Unit routinely monitor the volume of water usage by installing measuring devices at each water source location. [303-3][EM-MM-140a.1]
Water and Pollutant Load Management [303-1, 303-2, 303- 4, 303- 5][EM- MM-140a. 2]
We have a policy that refers to the Ministry of Environment and Forestry following the Decree of the Minister of Environment and Forestry No. SK .242/MENLHK/SETJEN/PKL.1/6/2020 concerning the Extension of Wastewater Discharge Permit to the Sea on behalf of PT Timah Tbk Metallurgical Unit to routinely monitor, regulate, supervise, and evaluate water use with a focus on conservation, efficient use of water resources, and water reuse. The goal is to optimize the use of water in every operational activity.
On the other hand, to reduce the water pollutant load, the Company applies a closed water circulation system (closed system) where all water (100%) used in land mining operations is recycled water. The system ensures that the water quality at the end of the production process can be returned to the environment with optimal quality.
Measurement of the volume of water recycled uses data from a flowmeter or rotameter, which is a device to record the volume flow rate of liquids including water, installed in the water management system. Throughout 2023 there were no incidents of non-compliance with wastewater or effluent discharge limits.
