Performance of 2023 Target
Lost Time Injury Frequency Rate (LTIFR): 5.3
Injury Severity Rate (ISR): 48.9
Fatality Rate (FR): 0 cases
Overall accidents and Lost Time Injury have decreased by 50% compared to the year 2023. There were zero fatalities within the year 2025.
Greenhouse Gas Management

Thai Wah has committed to achieving Net Zero greenhouse gas emissions by the year 2050. The Company has managed to reduce greenhouse gas emissions through the implementation of the 3T strategy, which includes:

  • Traceability - consistently tracking the sources and quantities of scope 1, 2, and 3 greenhouse gas emissions.
  • Transition - reducing of greenhouse gas emissions from controllable sources, such as energy consumption. This includes enhancing the manufacturing system within the factory and introducing innovations to mitigate greenhouse gas emissions in the production process.
  • Transformation - encouraging behavioral and cultural change internally and externally, such as integrating sustainability practices into core strategies and aligning with customer expectations regarding the Company's operations and sustainability goals
Greenhouse Gas Emission 2021 2022 2023 Target 2024
Greenhouse Gas Emission Scope 1 and 2 (ton CO2e)* 89,127 58,960 58,297 55,382

*The quantity of greenhouse gas emissions from factories, including Bang Lane branch, Mae Sot branch, Thakanto branch, Phimai branch, and affiliated companies, namely Thai Nam Tapioca Co., Ltd. and Tapioca Development Co., Ltd. The data has not been externally audited. Plan for external audit to be conducted in H2 2024 for latest year.

Over the past three years, the Company has implemented activities and projects to reduce greenhouse gas emissions, such as using alternative energy from sunlight and biogas.

Improvements in production processes for resource-efficient use and improvement of wastewater treatment systems have enabled the Company to reduce greenhouse gas emissions by over 30,000 tons of carbon dioxide equivalent or approximately 30% from the year 2021. In addition to reducing emissions within scopes 1 and 2, Thai Wah continues to explore innovations for reducing greenhouse gas emissions throughout the entire supply chain continuously.

Thai Wah has increased its utilization of renewable energy, positioning itself as a leader in sustainable energy. The transition to solar energy is currently operational with a capacity of 2.43 mega watts installed at the food manufacturing plant in Bang Lane District, Nakhon Pathom Province. This shift not only increases the proportion of renewable energy usage but also contributes to cost savings in the energy sector.

Solar Energy Usage 2019 2020 2021 2022 2023
Electricity Generated by Solar Rooftop (kWh) 589 1,405 1,406 2,769 2,796
Electricity Saved by Solar Rooftop (Million Baht)* 2 5 5 11 12

Thai Wah systematically manages the environment by generating electricity from wastewater and by-products of production, creating a significant source of renewable energy for the Company. Currently, Thai Wah operates two biogas power plants: one owned by Thai Nam Tapioca Company Limited and the other located at the Thakanto branch.

Biogas Power Plants 2019 2020 2021 2022 2023
Electricity Generated by Biogas Power Plant (kWh) 20,137 37,376 31,571 27,012 25,672
Electricity Saved by Biogas Power Plant (Million Baht)* 60 150 112 94 96
Waste Management

Thai Wah aims to reduce waste and maximize resource utilization, following a strategic approach to enhance raw material and existing resource efficiency while minimizing waste throughout the production process. The Company upcycles waste materials, creating new products and adding value. Examples include:

  • Utilizing biogas from wastewater and cassava pulp for heat and electricity production. Over 7,000 tons of cassava pulp were used to produce biogas during the past year.
  • Incorporating cassava pulp into animal feed production. Thai Wah processed more than 300 tons of cassava pulp from production into animal feed nutritional additives under the brand “Thai Win”.
  • Producing organic fertilizer from cassava pulp effluent for use in the Company’s experimental plots and distribution to local farmers.
Water Management

The Company is committed to sustainable water management, conducting a comprehensive analysis of all production processes involving water usage. Necessary steps are taken to enhance efficiency and reduce water consumption. The Company aims to achieve a minimum annual reduction of 5% in water usage for starch production facilities and 3% for food production facilities. Regular inspections and maintenance of machinery ensure they are in optimal condition for efficient water usage.

  • Reduction: Evaluate the consistent water quantity from water sources to plan water usage in the production process. Assess the guidelines for water use throughout the production process to reduce water consumption at each stage through the integration of innovations and continuous maintenance and improvement of machinery.
  • Reuse: Reuse water that has undergone the production process in the initial stage of cassava roots washing. The recirculated water undergoes treatment to remove suspended solids before being reused.
  • Recycle: All wastewater from the production process undergoes treatment using an aeration system and is then distributed to farmers in the nearby area for agricultural activities.
