France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO₂ emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.

Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the project.

India: During the second quarter of the 2023 financial year, Shree Cement recorded standalone sales of US$459m, up by 18% year-on-year from US$389m in the second quarter of the 2022 financial year. The figure represents a quarter-on-quarter drop of 10% from US$510m during the first quarter of the present financial year. The producer reported cost increases as a percentage of revenues to 33% for fuel and power, 7.6% for raw materials and 1.6% for inventory costs during the quarter. It said that this resulted in a 67% year-on-year drop in its standalone net profit to US$22.9m, from US$70.2m in the second quarter of the 2022 financial year.

India: Adani Group's flagship company, Adani Enterprises, has clarified that it is 'not evaluating' the possibility of acquiring Jaypee Group's cement business. Bloomberg has previously reported that Adani Enterprises was in 'advanced talks' to acquire the 10Mt/yr-capacity business for US$606m.

India: Birla Corporation won bidding for Madhya Pradesh's Marki Barka coal mines on 15 October 2022. The producer said that the asset will provide fuel security and cost optimisation for its cement operations.

New Zealand: Fletcher Building subsidiary Golden Bay Cement has co-processed 80,000t of waste in production of its EcoSure reduced-CO₂ general-purpose cement at its Golden Bay, Whangarei, cement plant. The plant has achieved a coal substitution rate of 50%. It has processed various waste streams, including 3 million used tyres. EcoSure cement generates CO₂ emissions of 699kg/t of product, 20% less than its imported alternatives, according to Golden Bay Cement. Fletcher building CEO Nick Traber said that this figure is 'simply our starting point.' The company's next target is to achieve a 30% CO₂ reduction by 2030.

Traber said "We needed to think outside the box, or rather the cement bag to be more precise. The challenge was around what enhancements we could make to our manufacturing processes at our Golden Bay cement works in order to improve the plant's sustainability. We quickly realised that consuming used tyres and wood waste as alternative fuels was a win-win. When we started with the idea in 2015, we were aiming to replace 15% of coal with end-of-life tyres. Fast forward to 2022, and our rate of coal substitution is now at 50%, which has obviously delivered further reductions in carbon emissions, as well as helping to offset increased coal costs."
