Waste and unused materials management projects

S-Brick: Sustainable Brick, Green Brick Project

Based on the concept of the Circular Economy, the Company uses ashes from burning wood chips, which are biomass fuels used in boilers, as an ingredient in paving bricks for landscape improvement in factories and surrounding communities. This initiative aims to minimize waste sent to landfills and reduce environmental impacts associated with waste disposal. Moreover, it generates value and benefits from waste.
In 2024, the Company operated through five branches of blocked rubber factories, namely Sri Trang Agro-Industry Public Company Limited in Kalasin and Sa Kaeo branches, Rubberland Products Company Limited in Mukdahan, Buriram and Bueng Kan branches.

Useful Soil project

The Company has implemented the Useful Soil project continuously by using sludge from the wastewater treatment system, which is analyzed to contain a high quantity of nitrogen, an essential nutrient for plant and tree growth, and has no contamination of harmful heavy metals as soil improvement material for agriculture, which creates benefits for farmers and communities. In 2024, the company implemented projects in 3 factories: Sri Trang Agro-Industry Public Company Limited, Pattani, Narathiwat and Thung Song Branch.

Reduced fertilizer purchasing costs for 11 farmers in the community, amounting to a total value of 1,431,333 baht.
The company was able to reduce the amount of sludge sent from its wastewater treatment system to landfill by 429 tons

Waste Bank project

The Company implemented the ‘Recyclable Waste Bank’ project to raise employees’ awareness of waste-related issues and impacts, as well as to promote proper waste segregation through waste-sorting activities. In 2024, the project was implemented across all 29 factory sites, resulting in 46,046 kilograms of waste being segregated for recycling. In addition, the project was registered under the Low Emission Support Scheme (LESS) with the Thailand Greenhouse Gas Management Organization (Public Organization: TGO)

Benefits received

A total of 1,274 employees recognized the importance of waste segregation for recycling and registered as members of the Waste Bank
Reduced greenhouse gas emissions by 140,035 kgCO₂eq, equivalent to planting 8,697 Sri Trang trees.
