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: 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.

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."

Tunisia: Carthage Cement recorded a fall in turnover of 2% year-on-year to US$133m at the end of the 2024 financial year, ‘in an economic context marked by numerous challenges’, according to local news reports. Despite this, the company recorded a rise in cement production and clinker production, to 1.82Mt (+3% year-on-year) and 1.57Mt (+1% year-o-year) respectively. Local sales rose by 2% year-on-year to US$109m, while exports fell by 30% to U$12.6m. This decrease was reportedly mainly due to a strategic decision to limit export clinker sales in view of ‘unattractive’ market conditions. The producer reduced its debt by 10% to US$101m.
