UltraTech Cement Limited, India’s largest cement and ready-mix concrete (RMC) company from Aditya Birla Group, announced the signing of a collaboration agreement with the Institute for Carbon Management (ICM) at the University of California, Los Angeles (UCLA) to pilot a groundbreaking new technology The Zero Carbon Lime (ZeroCAL) developed by ICM that can significantly reduce carbon dioxide emissions from cement production. ICM, in partnership with UltraTech, will build a first-of-a-kind demonstration plant for the technology at one of UltraTech’s integrated cement manufacturing units.
The Zero Carbon Lime (ZeroCAL) process, developed by ICM researchers, can eliminate nearly 98% of carbon dioxide emissions associated with limestone decomposition in cement manufacturing. UltraTech will be the first company globally to implement the ZeroCAL process at scale through a demonstration plant that will produce several metric tons of zero-carbon lime per day. UltraTech’s partnership with UCLA aligns with its broader sustainability goals and its focus on developing and adopting innovative technologies to decarbonise its operations.
To accelerate its decarbonisation efforts, UltraTech is collaborating with technology startups to explore the use of emerging decarbonisation technologies including kiln electrification and carbon capture & storage.
