The company prioritizes efficient resource utilization and regulatory-compliant environmental management to minimize impacts on local communities. It utilizes fully recyclable ferrous scrap as the primary raw material across all three facilities while monitoring CO₂ emissions and measuring air pollutants—such as NOx, SOx, CO, and particulate matter—to ensure compliance with regulations and Environmental Impact Assessment (EIA) standards. Furthermore, the company implements a “Zero Discharge” water management approach and promotes proper waste management through training for employees and contractors, aiming to raise awareness and reduce environmental impact.

Tata Steel (Thailand) Public Company Limited (TSTH) recognizes the importance of efficient water management as a key component of its sustainability strategy and operational excellence. The Company is committed to optimizing water usage across its operations, reducing freshwater consumption, and enhancing resource
efficiency in line with its environmental objectives and industry’s best practices. To support these commitments, TSTH has implemented systematic measures for
monitoring, verifying, and improving water consumption performance across all plants. These initiatives aim to ensure data accuracy, strengthen operational control, and drive continuous improvement toward achieving the Company’s water reduction targets.
Management Approach
TSTH emphasized efficient water utilization and proper wastewater management by implementing the zerodischarge principle across its production processes.
Treated wastewater is reused to support sustainable and clean manufacturing practices. These initiatives are designed to reduce freshwater usage, minimize
environmental impact, improve resource efficiency, and ensure compliance with applicable environmental regulations, while supporting the Company’s long-term
sustainability objectives.
Water Stress Risk Management
TSTH recognizes water as a critical resource in steel manufacturing and has assessed water-related impacts, risks, and opportunities as primarily arising from its internal operations. Based on a water stress assessment using the World Resources Institute (WRI) Aqueduct database, the SISCO Plant in Saraburi is located in an area classified as extremely high water stress, while the NTS Plant in Chon Buri and SCSC Plant in Rayong are located in areas classified as high water stress.
These locations may pose risks to operational continuity due to water availability constraints, increased competition for water resources, and potential regulatory restrictions. The Company therefore closely monitors water availability and consumption across all plants and treats water management as a critical operational risk.
To enhance water efficiency and resilience in water-stressed areas, TSTH improves cooling systems, promotes water recycling and reuse, upgrades infrastructure to reduce water losses, and develops alternative water sources, including rainwater harvesting and backup water storage. Regular inspections and monitoring are also conducted to identify leakage points and ensure efficient water use across operations.
Key Action Plan
In FY2027, the Company will focus on strengthening water management practices across its operations as a key priority to reduce freshwater withdrawal and enhance water use efficiency. At the NTS plant, cooling towers will be reconditioned and replacement cooling tower Q2/1 cell no.1-4 to improve operational efficiency and minimize water splashing, thereby reducing unnecessary water losses. At the SCSC plant, a new pipeline connecting rain gutters from the SP building to storage tank TK3 has been installed to increase rainwater harvesting and on-site water reuse and replacement blending guide at CCM
Steel Plant for reduce water leaked.
In addition, at the SISCO plant, the Company will initiate the arrangement of dry-season backup water storage and implement a plan to utilize water from Backup Water Storage 1, while refilling from Backup Water Storage 2. These measures are expected to reduce freshwater abstraction from the river by approximately 49,721 cubic meters per year. Collectively, these initiatives aim to support sustainable water resource management, reduce dependency on freshwater sources, and reinforce the Company’s long-term water stewardship commitments.
Targets and Goals
Highlighted Implementation and Activities
Water Efficiency Improvements
To achieve the targeted reduction in freshwater consumption, TSTH has implemented several key initiatives across all plants. At the SCSC Plant, daily
inspections are conducted to identify and rectify water leakage points, alongside the replacement of cooling towers (HE2 and HE2A) to enhance operational efficiency and reduce water splashing. At the NTS Plant, the
replacement and optimization of cooling towers (Q2/1, Cells no. 5–8), as shown in the figure, together with pipeline upgrades from the Filtration Plant to the Water
Plant, have improved system efficiency, reduced water losses, and optimized water usage in cooling processes.
At the SISCO Plant, an HDPE geomembrane has been installed in the new reservoir to improve water retention efficiency and minimize seepage losses, supporting
more effective water storage and long-term water management. Routine inspections are also carried out across all plants to detect and address leakage points,
ensuring continuous improvement in water efficiency.

Verification of water consumption data
TSTH has established a structured approach to verify water consumption data and improve water efficiency across all operations. The Company focuses on ensuring
data accuracy while implementing practical measures to minimize water loss and enhance operational. Key initiatives include the following:
1. Daily inspection and leakage control: Conduct daily inspections across all three plants to identify water leakage points and implement corrective
actions promptly to prevent unnecessary water loss.
2. Cooling tower improvement: Replace and upgrade cooling towers at both SCSC and NTS plants to improve efficiency, reduce water splashing, and minimize water makeup requirements and operating temperature.
