Italy: Holcim announced its acquisition of Nicem, Italy's ground calcium carbonate market leader. The group said that it plans to use Nicem's ground calcium carbonate as raw material in production of its ECOPact and ECOPlanet reduced-CO₂ cement and concrete range.

Holcim's Europe regional head Miljan Gutovic said “Nicem complements our existing operations perfectly and allows us to further leverage our expertise in green formulation, opening a new source of alternative materials to decarbonise our ready-mix concrete. I look forward to welcoming the employees of Nicem to the Holcim family, whose valuable expertise will help us accelerate green growth.”

Canada: Lafarge Canada’s Brookfield plant in Nova Scotia has switched to Portland Limestone Cement (PLC) production. The unit will now manufacture the company’s OneCem PLC product. It is the cement producer’s third plant to transition to PLC production in 2022 following the Bath plant in Ontario and the Richmond plant in British Colombia.

Andrew Stewart, the Vice President of Cement at Lafarge Canada (East), said, “We have been steadily moving the needle forward when it comes to cement decarbonisation and we will continue to honour our commitment in progressing our greener portfolio in Eastern Canada over the coming years.”

US: Titan America has successfully converted its cement operations to 100% Portland limestone cement (PLC) production. As part of its transition, the producer established two new 70,000t storage domes to serve its key markets.

President and CEO Bill Zarkalis said "I would like to thank all members of the Titan America team who are able and energised to provide the highest performing products to our customers, and do so with our 2030 goals for a sustainable future at top of mind. Our conversion to 100% Type IL PLC production and our expanded investments to deliver lower carbon products and solutions to customers showcase the progress we have made and our commitment to accelerate our contribution to addressing climate change."

Türkiye: Adocim says that it has successfully commissioned a new four-silo cement terminal at the Port of Samsun, Samsun Province. The producer says that the terminal has a storage capacity of 45,000t. The facility will serve the producer's Portland limestone cement (PLC) export operations to countries including the US.

Parent company Titan Cement Group said "This new investment will enable us to further increase our sales of lower carbon cement, contributing to our group’s Net Zero goal towards a greener and more sustainable future."

US: Summit Materials has announced that its cement plant in Hannibal, Missouri, has been converted to produce 100% Portland limestone cement (PLC). Since 4 August 2022, the plant has only produced PLC, which has embodied CO₂ emissions around 10% lower than ordinary Portland cement (OPC). The company said that the conversion marked an important step towards reaching its overall 2030 and 2050 decarbonisation targets, which were announced in April 2022.

The Hannibal plant is the company's second conversion to PLC in 2022. It earlier converted Continental Cement's Davenport plant to 100% PLC production in April 2022.

US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."

US: Lehigh Hanson’s Lehigh Cement plant in Union Bridge, Maryland plans to fully switch from Ordinary Portland Cement (OPC) to Portland limestone cement (PLC) production by January 2023. It will manufacture its EcoCemPLC product. The company says that the Union Bridge plant is currently the company’s largest cement plant in North America.

The decision to move to PLC follows similar changes at the company’s Mason City plant in Iowa and three cement plants in Indiana. Lehigh Hanson produced over 2Mt of PLC in 2021 and it says it is set to double this figure in 2022.

US: The Nevada Department of Transportation has approved the use of Portland limestone cement (PLC) for road construction and repairs. The department expects the move to reduce CO₂ emissions by 4000t/yr. It uses 45,000t/yr of cement in its projects. Local press has reported that transport contributed 35% of Nevada’s CO₂ emissions in 2022, making it the largest single source.

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.

Mexico: GCC has announced its plan for a 100% Portland limestone cement (PLC) transition of its Samalayuca, Chihuahua, cement plant. The producer says that the plant will complete its transition in July 2022. It said that the move is part of its CO₂ emissions reduction roadmap.
