UltraTech Cement Limited, India's largest cement and RMC producer, has signed a collaboration agreement with the Institute for Carbon Management (ICM) at UCLA to pilot a pioneering technology—Zero Carbon Lime (ZeroCAL). This innovative process, developed by ICM, aims to drastically cut carbon dioxide emissions in cement production.
As part of the agreement, ICM and UltraTech will establish a demonstration plant at one of UltraTech’s cement manufacturing units, making UltraTech the first to implement the ZeroCAL process at scale. The technology can eliminate nearly 98% of CO2 emissions from limestone decomposition in cement manufacturing, a significant step toward sustainable production. This initiative aligns with UltraTech’s commitment to adopting advanced technologies for decarbonizing its operations.
UltraTech is fully committed to realising its Net Zero Goal by 2050. As an industry leader UltraTech is constantly exploring partnerships to overcome the technological barriers to decarbonise cement manufacturing.” said Mr. K C Jhanwar, Managing Director at UltraTech. "We are excited to collaborate with UCLA on this groundbreaking project. Partnerships like these, which place an emphasis on developing and deploying new and emerging technologies, will be a key enabler in our sector's efforts to accelerate decarbonisation and deliver carbon neutral concrete by 2050,” he added.
The ZeroCAL approach is a powerful solution to eliminate carbon emissions associated with the process of cement production within the existing industrial paradigm of Ordinary Portland Cement (OPC) clinker production and without a need for carbon capture and storage,” said Professor Gaurav Sant, ICM director and the study’s corresponding author and the Pritzker Professor of Sustainability at the UCLA Samueli School of Engineering. “It effectively eliminates the carbon dioxide emissions resulting from limestone’s decomposition while providing clean hydrogen and oxygen to heat the cement kiln,” he added.
