Cement major Dalmia Cement (Bharat), a subsidiary of Dalmia Cement, announced it will build a large scale facility of 500,000 tonne per year carbon capture at its cement plant in Tamil Nadu.

The company aims to become carbon negative by 2040. “It is time to resolve the climate crisis. Capturing process emissions from cement manufacturing will be critical towards reaching net zero by 2040 and therefore, our approach is to set up scalable large demonstration projects on carbon capture with multiple utilisation streams,” said Mahendra Singhi, MD and CEO, Dalmia Cement (Bharat).

Dalmia Cement (Bharat) has signed a Memorandum of Understanding with Carbon Clean Solutions (CCSL) UK. The latter provides low-cost carbon dioxide (Co2) separation technology for plants based on its patented CDRMaxTechnology.

While small-scale carbon capture plants have been commissioned in few cement plants in China and Europe, the plant at Tamil Nadu would be the first large-scale plant of this capacity in the cement industry.

The cement major plans to identify multiple utilisation streams for the Co2 that is captured from this large-scale plant, including direct sale for use in other industries and manufacture of chemicals.

"Decarbonising the cement industry is absolutely key to reaching ‘net zero’ emissions. By combining our low-cost modular Co2 capture technology with viable Co2 reuse alternatives, we plan to deliver a full solution to early movers like Dalmia Cement," said Aniruddha Sharma, CEO and co-founder of CCSL.

Dalmia Cement (Bharat), has been invited to speak at Climate Action Summit of UN Secretary-General on September 23 about the goal to become carbon negative by 2040. The company announced a slew of measures to move towards sustainable operations.
