UltraTech Cement, which is the cement flagship company of the Aditya Birla Group, will invest INR 13,000 crores in expanding its Indian grey cement capacity by another 21.9 Mta in the 3rd expansion phase, which starts after FY 25 and will end in FY 27. The mode of financing is by internal accruals. The investment is for a mix of brown field and green field projects including split grinding plants. However, the expansion also includes investments in setting up additional WHR-systems and other projects such as AF installations to reduce the carbon footprint.
