Mali: A foundation stone has been laid for the new Atlas 0.8Mt/yr cement plant in Dio-Gare. The project had an investment of around US$80m, according to Mali Actu. It is expected to be completed in mid-2025. The project is being financed by Papa Oumar Samake, the head of Atlas. The President of the National Transitional Council, the Prime Minister, the Minister of Territorial Administration and Decentralisation, the Minister of Industry and Trade, the Governor of the Koulikoro region and the local mayor attended the ceremony.

Russia: A study commissioned by the National Association of Manufacturers of Building Materials and the Construction Industry (NOPSM), SM PRO and Soyuzcement, the national cement manufacturing union, has found that 80% of components required for repairs and upgrades to cement plants in Russia are manufactured abroad. The research was intended to assess the sector’s requirement for foreign equipment and to determine the prospects for import substitution. The results of the survey were presented in late May 2022.

Anton Solon, the executive chair of NOPSM, noted that Russian cement sector holds a ‘critical’ dependence on imported equipment. He said that domestic analogues were either ‘significantly’ inferior to imports or simply not available. The main equipment affected included separators, burners, drives, compressors and grinding mills. Parts for packaging lines, some types of quarry equipment, grinding media, refractories, additives and linings were also negatively affected. However, he did point out that low-efficiency and large-sized gas cleaning plants (including bag and electrostatic precipitators) were produced domestically. Vyacheslav Shmatov, the chairman of Soyuzcement, called for the development of local engineering products to remedy the situation.

Germany: ThyssenKrupp Industrial Solutions’ Polysius division says that it has been commissioned by Buzzi Unicem, HeidelbergCement, Schwenk Zement and Vicat to build a pure oxyfuel kiln system at the Mergelstetten cement plant as part of the Cement Innovation for Climate (CI4C) project. No dates of the start of construction or final project commissioning of the industrial trial have been disclosed. CI4C was originally formed in 2019.

The Polysius pure oxyfuel process is a new type of clinker production process in which the otherwise normal ambient air is replaced by pure oxygen in the kiln combustion process. One advantage of the technology is that atmospheric nitrogen is eliminated from the clinker burning process leading to much higher concentrations of CO₂ in the exhaust gas compared to a conventional kiln. As such the process aims to concentrate, capture and reuse almost 100% of the CO₂ produced in a cost-effective manner. The medium-term goal is to further process the captured CO₂ with the help of renewable energy into products such as kerosene for air traffic.

Sweden: Cementa has completed its feasibility study for a carbon capture and storage (CCS) system at Slite cement plant in Gotland. The producer says that it will now proceed to the next stage of the project, with the aim of producing climate positive cement from 2030. Sister company Norcem is currently building a 400,000t/yr CCS system at its Brevik cement plant in Norway. Cementa says that its new system will have four times the capacity of that at the Brevik plant, and reduce Sweden's total CO₂ emissions by 3%. One or more of 'several storage solutions' currently under development in the North Sea will serve to store the plant's captured CO₂ emissions.

General manager Giv Brantenberg said "With the knowledge we have built up through our pioneering project at Norcem in Brevik, we now have a good picture of how to move forward in Sweden. The Nordic countries have what it takes to lead the climate transition in the construction sector."

UK: Hanson plans to install a C-Capture solvent-based carbon capture system at its Ketton cement plant in Rutland. The producer says that the technology reduces energy requirements per tonne of CO₂ by 40% compared to other capture systems.

Chief executive officer Simon Wills said “Carbon capture is a critical part of our strategy to decarbonise cement production, and essential if we are to reach net zero carbon by 2050. If successful, the C-Capture process has the potential to be rolled-out across other sites across the HeidelbergCement Group.”

Namibia: The Namibian government has granted Whale Rock Cement permission to resume production of its Cheetah brand cement at its Otjiwarongo grinding plant. Authorities suspended operations at the plant on 10 May 2022.Labour Ministry acting executive director Lydia Indombo cited multiple contraventions of occupational safety regulations, including failure to issue personal protective equipment (PPE), failure to maintain good housekeeping, lack of sanitary conveniences and lack of first aid equipment, as the cause of the suspension.

Indombo said "The ministry conducted verification inspections on 16 and 20 May 2022 to evaluate the compliance on the identified shortfalls and is satisfied with the level of compliance." She added that the ministry had recommended the resumption of production activities.

Zimbabwe: Germany-based Gebr. Pfeiffer says that a new MVR 3070 C-4 mill for cement grinding is due to be commissioned at Holcim Zimbabwe’s integrated plant at Manresa near Harare. The order was handled by the Chinese contractor CBMI.

The roof at the plant collapsed over a cement mill in October 2021 leading to a reduction in production volumes at the plant. The mills were restarted in February 2022 but one of the one of the existing cement ball mills was decommissioned. This mill is being replaced by the new vertical roller mill supplied by Gebr. Pfeiffer. It is expected to double the plant’s cement production capacity after it is commissioned in the second quarter of 2022.

US: Buzzi Unicem USA plans to switch from producing Ordinary Portland Cement (OPC) to Portland Limestone Cement (PLC) at all of its plants by the end of 2022. It said that it intends to transition from traditional ASTM C150 type I and II (OPC) cements in favour of ASTM C595 type IL cement (PLC). So far its Cape Girardeau and Festus plants in Missouri, Greencastle plant in Indiana, Maryneal plant in Texas and Pryor plant in Oklahoma have already completed the move to the PLC. The San Antonio plant in Texas will complete its transition in June 2022, the Chattanooga plant in Tennessee will switch its product line by September 2022 and the Stockertown cement plant in Pennsylvania will complete its conversion later in 2022. The company added that its engineers will continue working to increase the limestone content in cement by up to the permitted 15% and develop High Early Limestone cement, along with other new cement products with reduced clinker content.

Germany: Cemex has inaugurated the Carbon Neutral Alliance at its integrated Rüdersdorf cement plant. The initiative is intended to accelerate the development of the site into the world’s first carbon-neutral cement facility by 2030. Jörg Steinbach, Brandenburg’s Minister of the Economy, Fernando A Gonzalez, the chief executive officer of Cemex, the Mexican ambassador to Germany and representatives from Sasol attended the event.

The Carbon Neutral Alliance comprises a network of over 20 private and public organisations, dedicated to industrial decarbonisation. Among the technologies being introduced at Rüdersdorf include a waste heat recovery project scheduled for the summer of 2022, the development of renewable energy generation and a scheme to produce aviation fuel onsite in coordination with Sasol and Enertrag.

In 2020 Cemex announced its decarbonisation target of reducing its CO₂ emissions by 40% by 2030 compared to 1990 levels. This target is expected to be achieved in Europe in 2022. By 2030, Cemex intends to reduce emissions at its European sites by 55%, in line with European Union's new strategy to reduce CO₂ emissions. Cemex has also announced its goal to achieve net-zero carbon emissions in concrete by 2050.

India: Jindal Group has signed a memorandum of understanding with the state government of Chhattisgarh for the establishment of its planned Raigarh cement plant. The Times of India newspaper has reported that the plant will have an integrated capacity of 2.5Mt/yr, in addition to a further 2.5Mt/yr in clinker capacity. It will also operate a 12MW waste heat recovery (WHR) plant.
