India: A committee has identified environmental compliance failures at the Adani-owned ACC cement plant in Barmana, Bilaspur district, according to The Indian Express.

The inspection conducted revealed inadequate dust emission controls, missing three-layer tree plantation and deficient truck-tyre washing systems at the plant. Only one kiln was operational at 40% capacity during the visit, as the plant is undergoing maintenance from 3 January to 8 February 2025. Therefore, the committee has requested an additional eight weeks to submit its report, so that it may conduct a more thorough investigation once the plant is operating at full capacity.

The Himachal Pradesh Pollution Control Board has previously imposed a US$149,000 fine on the plant in April 2022 for air quality breaches and untreated water discharge, with at least seven complaints lodged against the plant by local residents over the last three years.

India: Aditya Birla Group subsidiary UltraTech Cement has entered talks to acquire Heidelberg Materials' 69% stake in HeidelbergCement India, Reuters reports. Executives from Aditya Birla Group have reportedly met with Heidelberg Materials' management to discuss the acquisition. Heidelberg Materials’ stake has been valued at approximately US$391m.

The talks come after the Economic Times reported that Ultratech’s rival Adani Group was in discussions to buy Heidelberg's stake back in October 2024.

US: Carbon capture firm Nuada and lime producer MLC (formerly Mississippi Lime Company) have signed a memorandum of understanding to demonstrate net-zero lime production at MLC's Ste. Genevieve plant in Missouri. The partners aim to contribute to a reduction of the facility’s CO₂ emissions by 95%.

Nuada’s technology uses metal-organic frameworks as a solid sorbent alongside vacuum swing pressure adsorption, which utilises pressure rather than heat to separate CO₂ from flue gases.

Co-CEO Jose Casaban said "Our breakthrough in carbon capture technology sets a new standard for energy efficiency, paving the way for transformative decarbonisation in hard-to-abate sectors like lime manufacturing. Through this collaboration with MLC, we are driving the next generation of carbon capture forward, setting a new standard for emissions reduction and sustainability in the lime industry."

India: JK Cement has entered a joint venture with Saifco Cement, through which it will expand its offering in northern India. JK Cement will acquire a 60% stake in Saifco Cement for US$20.1m to expand in Jammu and Kashmir, where Saifco owns limestone reserves of 129Mt across 144 hectares. The acquisition will involve both the companies working together to increase the capacity of cement production by leveraging the expanse of the limestone reserves in the next five years, according to a press release.

JK Cement CEO Madhav Singhania said "Cement demand typically leads economic expansion by a factor of 1.2 in regions with significant infrastructural development opportunities, and Kashmir is undoubtedly one of these regions."
