India: The National Commission for Scheduled Tribes has directed the district collector of Chandrapur to supply details of compensation paid to local indigenous people since 1979 for the establishment of a limestone mine on their land in Maharashtra by UltraTech Cement. The Times of India newspaper has reported that the authorities allegedly conveyed 63.6 hectares of designated tribal land for use by the cement company.

Montenegro: UK-based private equity firm Chayton Capital has agreed to fund the feasibility study for the establishment of a joint public/private building materials production complex at the site of the Plejevlja energy hub. The complex will include a cement plant and cement bonded particle boards plant. Emerging Market Watch News has reported that the firm will also be involved in the modernisation of a coal-fired power plant at the site. The total budget for the project is Euro700m.

US: A team from the Massachusetts Institute of Technology (MIT) has developed a new method to sequester CO₂ in concrete before curing it. The method is based on the addition of bicarbonate of soda, which reacts with cement to produce a calcium carbonate-calcium silicone hydrate composite. The Journal of Engineering has reported that the method adds the benefits of CO₂ mineralisation during production and casting, doubling the mechanical performance of early-stage concrete. It also eliminates the effects of carbonation reactions in cured concrete, which weaken the concrete by lowering its alkalinity, which accelerates the corrosion of rebar. The method has the potential to sequester 15% of CO₂ emissions from cement production.

The team said “The pre-curing capacity of concrete to sequester CO₂ has been largely underestimated and underutilised. Our new discovery could further be combined with other recent innovations in the development of lower carbon footprint concrete admixtures to provide much greener, and even carbon-negative, construction materials.”

China: China Resources Cement has forecast a loss of US$4.46 – 5.73m during the first quarter of 2023, which ended on 31 March 2023. Dow Jones Institutional News has reported that the group attributed the anticipated scale of the loss to a year-on-year decline in its cement prices.

India: UltraTech Cement says that it has made a second deployment of GreenLine liquefied natural gas (LNG)-powered cement trucks in its cement operations. Indo-Asian News Service has reported that the new trucks will operate from UltraTech Cement’s Pune cement terminal in Maharashtra. GreenLine says that its LNG trucks have 28% lower CO₂ emissions than ordinary cement trucks, equating to reductions of 24t/yr per truck for UltraTech Cement.

The cement producer’s associate vice president Tanmay Pradhan said “We are dedicated to creating a sustainable future, and we are fully committed to collaborating with our partners and stakeholders to achieve our goal of a cleaner environment. Our association with GreenLine is a step forward in our ongoing efforts to decrease emissions, enhance energy efficiency, and promote sustainability."
