Green Procurement

We are dedicated to continuously promoting the procurement of environmentally friendly raw materials, products, and services for use in our production processes and operations. However, in 2023, the value of green procurement amounted to only 113.75 million baht, representing a decrease from the previous year. This decline can be attributed to changes in the government’s policy, specifically the reduced use of Natural Rubber Modified Asphalt Concrete. Consequently, the demand for raw materials used in the production of such products significantly decreased
