Sustainable Water Management

Currently, water-related risks have intensified due to climate change and the increasing demand for water driven by population growth and industrial development. The company recognizes the potential impacts of these risks on its business operations, including risks related to water quantity and quality, regulatory changes and pricing structures, as well as stakeholder conflicts arising from water usage. In response, the company is committed to implementing appropriate preventive and mitigation measures aligned with Sustainable Development Goal 6 (SDG 6) and Thailand’s 20-Year Water Resource Management Master Plan

Management Guidelines

Water management using the

3Rs

principle (Reduce, Reuse and Recycle)
Promote invention and improvement
to reduce water consumption in each process with
Kaizen and QCC
activities
Join and build partnerships with external agencies
to maintain water resources.
Consider the quality and quantity of water used to ensure
it does not affect the communities surrounding the factory

Water Resource Risk Management

The Company has analyzed the situation of water sufficiency (water-stressed areas) in all factory areas annually using the Aqueduct Water Risk Atlas tool of the World Resources Institute (WRI). In 2024, the results of the risk assessment found that 21 percent of the production areas were in areas with extremely high of water stress, while 8 percent of the operational areas were at high risk level of water stress.

Goal

Reduce new water withdrawals from water sources per product unit by
20%
compared to the base year 2022 by 2026.

Performance

In 2024, the Company’s total water consumption was 23,942,250.45 cubic meters, of which 22,365,821.73 cubic meters were treated water (recycled water) reused, accounting for 93% of the total water consumption.

Wastewater Management

The Company is aware of the potential impact of wastewater drainage on the environment and biodiversity of the communities surrounding the factory. The Company has installed a wastewater treatment system that complies with standards to control the efficiency of wastewater treatment and the quality of wastewater discharge meets legal requirements.

Management Guidelines

Always inspect and control the wastewater treatment system
to maintain its efficiency.
Develop a wastewater treatment system
for optimal efficiency
and maximum water reuse.
Apply technology and innovation
for inspecting and controlling wastewater treatment systems.

There are 2 types of treatment systems used as follows:

1. Aerated Lagoon

2. Activated Sludge

Additionally, wastewater from the concentrated latex plant, including Trang, Suratthani, and Kanchanadit branches, is equipped with the BOD online system. This system measures the amount of Biochemical Oxygen Demand (BOD) in treated wastewater and sends real-time BOD measurements to the Department of Industrial Works, to ensure that the wastewater discharged into public water bodies meets legal requirements.

Maturation Pond

Goal

The block rubber factory is able to reuse
100%
of the treated water.

Performance

The block rubber factory

has developed and improved the wastewater treatment process to achieve maximum efficiency and minimize odor impact, by constructing an emergency pond to contain serum water from cup lump rubber before it enters the wastewater treatment process. The block rubber factory can recycle the water after the treatment process and reuse it in all production 100% without having to discharge water outside the factory.

Concentrated latex factory

a total of 402,362.40 cubic meters of wastewater has undergone water quality treatment processes and meets the wastewater quality standards mandated by law. There have been no incidents of non-compliance with the law regarding the quality and quantity of wastewater discharged from the factory that significantly impacted the Company’s operations.

In 2024, the company had no incidents of non-compliance with regulations related to the quality and quantity of wastewater discharged outside the factory.
