US: Prometheus Materials' microalgae-based biocement has demonstrated 12 times greater sound absorption than ordinary Portland cement (OPC). Prometheus Materials produces its biocement at ambient temperature, with no process CO₂ emissions.

Japan: A Taiheiyo Cement plant will be one of two facilities to host carbon capture systems under the Tohoku West Coast carbon capture and storage (CCS) project. The Japan Organisation for Metals and Energy Security selected the project to advance to the feasibility study stage on 2 August 2023. The partners will now investigate technical issues in the entire CCS value chain, as well as commercial and social issues around transporting captured CO₂ by ship to temporary storage sites. Identification of permanent underwater storage sites is scheduled for 2024, with the design stage of capture, transport and storage systems scheduled to conclude in 2026. The Tohoku West Coast carbon capture and storage project will commence in 2030.

Taiheiyo Cement is committed to a 20% reduction of its CO₂ emissions between 2000 and 2030, while the Japanese government is committed to a 46% reduction between 2013 and 2030.

Our synergies with the Adani Group companies are lowering input costs, which is boosting EBITDA growth. Furthermore, our blueprint of improvements through group synergies and capital expenditure for efficiency and decarbonisation whilst creating opportunities, will redefine the cement industry landscape. These include lowering the clinker factor, diminishing energy intensity, implementing waste heat recovery (WHR) systems and augmenting renewable energy generation.” He added “Our long-term competitiveness remains robust, ensuring industry-leading profitability as we chase our ambitious growth goals. With a firm belief in our strategic approach, we are poised to continue our trajectory of outstanding performance as we are devoted to sustainable and responsible growth.”
