West Africa: Ciments de l'Afrique (CIMAF) plans to produce limestone calcined clay cement (LC3) at cement plants in West Africa. Parent company Omnium des Industries et de la Promotion (OIP) plans to build a calcined clay production facility in Burkina Faso to supply the material. Gulf Oil & Gas News has reported that OIP secured a Euro45m loan from World Bank Group’s International Finance Corporation on 10 October 2023. It will invest Euro32.4m in construction of its upcoming calcined clay production facility and Euro12.6m in
construction of solar power plants for three CIMAF subsidiaries in Burkina Faso, Chad and Mali.

CIMAF CEO Anas Sefrioui said "IFC's green loan provides essential long-term financing for our projects in Africa. Through the green loan structure, we are bringing the best practices in financing decarbonisation initiatives in the region. We look forward to reducing our carbon footprint and replicating these best practices in our African operations.”

EU/UK: EUROSLAG says that the use of ground granulated blast furnace slag (GGBFS) in cement production in the EU and UK between 2000 and 2022 has generated a cumulative reduction in CO₂ emissions of 408Mt. GGBFS replaced 716Mt-worth of raw materials over the period.

EUROSLAG Chair Thomas Reiche said "Resource conservation through secondary raw materials, especially in the construction sector, and lower emissions of climate-damaging CO₂, are of outstanding ecological and economic importance. The use of ferrous slags makes an important contribution to this. EUROSLAG is working multilaterally to master the enormous challenges in the coming years, above all the transformation of the steel industry, through research and adjustments to national and European regulations.”

Poland: Górażdże Cement has announced an investment of Euro261m in planned sustainability upgrades to its Górażdże cement plant in Opole Voivodeship, the Polish News Bulletin newspaper has reported. The Heidelberg Materials subsidiary plans to build a carbon capture installation, a green energy source and a facility to recycle construction and demolition waste for use in its cement production.

UK: The Cement 2 Zero project has successfully concluded its first trial melt of recovered cement paste in an electric arc furnace at the Materials Processing Institute’s Teesside campus. The project uses the paste as flux for electric steel recycling. Cambridge Electric Cement (CEC) has demonstrated that the ‘slag’ from this process can be ground into fine clinker that, when mixed with gypsum and supplementary cementitious materials (SCMs), produces net zero CO₂ cement. The Cement 2 Zero project to produce CEC’s cement at an industrial scale launched in March 2023, with US$7.85m in funding from UK Research and Innovation. Tarmac will grind the clinker from the project’s trial melts for testing in order to obtain certification and specification as a usable cement product.

UK: James Whitelaw will take on the role of managing director in Hanson UK’s newly-established recycling business line. He will be responsible for identifying opportunities to grow organically using the company’s existing capabilities and for integrating new acquisitions.

Whitelaw has held management roles in Hanson UK since 2001 and most recently served as aggregates managing director. Former concrete managing director Brian Charleton will replace him in this role, while Gordon Napier, previously concrete regional director, joins Hanson UK’s executive team as the new concrete managing director.

US: Sublime Systems’ Sublime Cement reduced-CO₂ cement has received an ASTM C1157 designation. InterestingEngineering News has reported that this enables builders to use it in various projects in line with international building codes. Sublime Systems’ cement consists of lime and silica produced by electrolysis using non-carbonate calcium compounds.

CEO Leah Ellis said "Our aim is to make a profound and lasting impact on global CO₂ emissions. The ASTM C1157 designation is a validation of our efforts to integrate low-carbon innovation into quality construction materials."

Australia: Adbri has awarded ABx Group a contract to supply 90,000 – 120,000t of bauxite to its Birkenhead, South Australia, cement plant over a five-year period from early 2024. Business News has reported a ‘conservative’ estimated value for the contract of US$5.4m. ABx Group will supply bauxite from its DL130 mining project. The project commands 13.7Mt-worth of bauxite reserves across three deposits. Mining is due to begin in October 2023. The parties have agreed an undisclosed price for the first shipment of bauxite under the contract.

ABx Group managing director and CEO Mark Cooksey said "This represents a significant milestone for ABx and endorses the suitability of our bauxite for the broader cement industry. It enables both parties to plan for ongoing supply with confidence. Importantly, regular mining operations to supply Adbri will increase ABx's ability to secure additional customers, for which there are active discussions."

India: Bokaro Steel Plant has won granulated blast furnace slag (GBFS) supply contracts with ACC and UltraTech Cement. Under the contracts, Bokaro Steel Plant expects to supply 1.3Mt of GBFS from its facilities in Jharkhand for use in cement production in the state. The Pioneer newspaper has reported that the contracts will run until August 2026.

Austria: Christine Gröll has taken over the role of head of material flow management and process control at Alpacem Zement Austria. The producer created the new role for Gröll, who will lead a dedicated team of eight people to achieve net zero CO₂ cement production at the company’s Wietersdorf cement plant by 2035.
