MUMBAI: Aiming at becoming ‘carbon negative’ by 2040, homegrown cement maker Dalmia Cement (Bharat) on Thursday announced that it will be building a large scale carbon capture facility at its cement plant in Tamil Nadu.

The facility which will have a capacity of 500,000 tonnes is being built with technology shared by UK based Carbon Clean Solutions (CCSL) , a company engaged in the low-cost carbon dioxide separation technology. Dalmia Cement (Bharat) has signed a MoU with CCSL for the same.

In a press release the company said that with the help of its association with CCSL, it will explore multiple utilisation streams for the environmentally polluting gas that is captured from this facility. It will also look at selling the captured effluent directly for use to industries like the chemicals industry.

“At Dalmia Cement, a progressive business enterprise that foresees the future today, we are committed to be a carbon negative cement Group by 2040. 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,” Mahendra Singhi , MD, Dalmia Cement (Bharat) said in a release.

Cement industry is one of the largest contributors to global carbon dioxide levels. In producing the building material, calcination of limestone , a key raw material for making cement, emits large amounts of the gas into the atmosphere. While there are certain types of cement that do not require the mineral to be calcified for producing cement, it is subject to availability of alternative minerals. Therefore, capturing the emitted CO2 is the only viable way to reduce its carbon footprint.

“Decarbonizing 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.
