Use of Hydraulic Concrete to Reduce Carbon Dioxide Emissions

19 November 2025

Supalai has adopted the use of Hydraulic Concrete in its construction projects to help reduce carbon dioxide (CO2) emissions generated during the production of cement, the main component of concrete and a significant source of CO2. Hydraulic concrete is designed to incorporate substitute materials such as fly ash or other pozzolanic materials, partially replacing Portland cement. This approach significantly reduces the consumption of natural resources and energy used in the production process.This initiative not only helps lower Scope 3 greenhouse gas emissions from material production and transportation but also enhances material efficiency, reduces construction waste, and supports the development of projects aligned with Green Building standards and the Company’s Net Zero target. Furthermore, it creates shared value with suppliers by encouraging construction material manufacturers to adopt more environmentally friendly production processes.

Supalai’s implementation approach includes selecting concrete certified for environmental and carbon reduction standards, collaborating with material suppliers who improve their production processes for energy efficiency and sustainable raw material management, and ensuring effective concrete usage to minimize construction waste.

The outcome of this initiative is a reduction in Scope 3 greenhouse gas emissions from cement production and material transportation, along with decreased consumption of natural resources and energy in the concrete production process. and supports environmentally friendly construction that aligns with the Company’s Net Zero target, while elevating the Company’s construction standards to meet Green Building requirements.
