Thailand’s Siam Cement Develops New Low-Carbon Cement

Bangkok-based Siam Cement Group (SCG) has developed a new low-carbon cement that has lowered emissions by 15%-20%.

“This cement was not developed just to be environmentally friendly, but to also enhance the performance of cement, meet customers’ needs in all scenarios, preserve natural resources and care for the world,” said Surachai Nimlaor, president of SCG’s cement and green solutions department.

According to Nimlaor, although the new formula has lowered emissions by 15%-20%, the long term goal is to develop formulas than can offer up to 50% lower carbon emissions. The proportion of low-carbon cement used in Thailand currently stands at 70%, SCG said it hopes that this will soon reach 100%.

SCG said it improved its manufacturing process by using clean energy sources and utilising waste heat generated during production, which has led to a 38% reduction in energy consumption.

It has also adjusted the raw material proportions to further reduce carbon emissions.

“Since cement production consumes a considerable amount of energy and emits carbon dioxide during the process, we decided to find out how we could reduce this impact,” Surachai said.

“With the initial low-carbon cement formula, we have reduced emissions by 15 to 20%. Moving forward, our goal is to develop new formulas that can reduce carbon emissions by up to 50%,” he added.
