US: 100 Workers at Continental Cement's Hannibal cement plant in Missouri are on strike against alleged unfair labour practices. IndustriALL Global Union has accused the producer of restricting employees' say in schedules, overtime and cross training requirements at the plant, as well as of withholding information necessary for bargaining. The union additionally alleged that the company was discriminatory in its termination of contracts. The workers have continued to work amid on-going contract renegotiations following the expiry of a collective agreement between them and the producer in May 2022.

IndustriALL Global Union said "Continental Cement’s actions have left workers no other options but to make their voices heard by striking against unfair labour practices. We are determined to fight for the fair contract. It's time for Continental Cement to follow the law and negotiate in good faith for a fair contract.”

US: CRH-subsidiary Ash Grove Cement has appointed Fernando Valencia as Vice President of Manufacturing – Central Ashgrove. He previously worked as a plant manager at LafargeHolcim’s Ste Genevieve plant in Missouri and the Portland Plant at Florence in Colorado. Prior to this he was the plant manager of Holcim US’ Hagerstown Plant in Maryland and also worked as a commissioning manager. Valencia holds a degree in mechanical engineering from the Anahuac University Network and a master’s degree in business administration from the University of Missouri - St Louis.

US: Total US cement shipments grew by 4% to 52.4Mt in the first half of 2022 from 50.4Mt in the same period in 2021. Data from the United States Geological Survey (USGS) shows that local shipments and imports rose by 3.5% to 44.1Mt and 7% to 8.31Mt respectively. The largest sources of imports of cement and clinker were Turkey at 4.57Mt, Canada at 2.19Mt, Mexico at 1.28Mt, Greece at 1.23Mt and Vietnam at 0.94Mt. The largest cement producing states in the reporting period, in descending order, were Texas, California and Missouri.

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.

US: Cement companies produced 79.2Mt of cement in 2021, according to United States Geological Service (USGS) data. The figure corresponds to a 0.1% year-on-year rise from 79.1Mt in 2020. Texas contributed 10.7Mt, 13% of the production total, followed by Missouri with 8.97Mt (11%) and California with 8.94Mt (11%).

US: LafargeHolcim US has announced the successful transition of two further plants to Portland limestone cement production. The company’s 4.5Mt/yr Ste. Genevieve, Missouri, cement plant and 2.4Mt/yr Alpena, Michigan, plant have begun exclusively producing its OneCem reduced-CO2 Portland limestone cement (PLC).

LafargeHolcim US’ manufacturing North vice president Michael Nixon said "LafargeHolcim is fully engaged in making carbon reduction an urgent priority and 100% dedicated to leading the market transformation needed for climate stability." He added "To achieve net-zero commitments by midcentury, we must start now in accelerating the adoption of low-carbon building solutions to mitigate the impacts of climate change."

LafargeHolcim US successfully transitioned its Midlothian, Texas, cement plant to PLC production in 2021.

US: LafargeHolcimUS and its subsidiary Geocycle have successfully completed a barge shipment of 2000t of reclaimed bottom ash and fly ash from a pond at CenterPoint Energy’s AB Brown coal-fired power plant at Evansville in Indiana. The delivery is the first under a new 6Mt multi-year coal ash recycling contract with the energy provider.

LafargeHolcim US will use the coal ash to replace clay and sand in cement production at its Ste. Genevieve cement plant in Missouri. The producer says that this will help to reduce the plant's consumption of raw materials. LafargeHolcim US and Geocycle have invested US$80m in infrastructure to extract, process, transport, store and recycle ash from the power plant. Geocycle has managed the on-going joint recycling initiative between LafargeHolcim and CenterPoint Energy since 2009.

LafargeHolcim US's chief executive officer Toufic Tabbara said “This milestone is a tangible example of how industry participants together can develop creative and efficient solutions that contribute to the circular economy. Together, LafargeHolcim, Geocycle and CenterPoint Energy will avoid landfilling for power plants and reduce the consumption of non-renewable raw materials. This is a clear win-win for people and our planet.”

US: LafargeHolcim US has revealed more information about a commercial-scale carbon-capture study based at its integrated Ste. Genevieve cement plant in Missouri. The project aims to deliver a front-end engineering design (FEED) study for a carbon capture retrofit that can separate up to 95% of CO₂ emissions at the plant. The captured CO₂ will be ‘pipeline ready’ for geological storage and analysis of the project socio-economic impact will also be part of the study. The US Department of Energy’s National Energy Technology Laboratory awarded US$4m to the Prairie Research Institute at the University of Illinois to work on the project in early October 2021. LafargeHolcim and Air Liquide are also making cost share contributions.

The design will use Air Liquide’s Crycocap FG system at the cement plant. LafargeHolcim US says that it combines pressure swing adsorption capabilities with cryogenic refrigeration technologies to achieve high CO₂ capture rates with high CO₂ purity rates. Notably, for a carbon capture project, the Ste. Genevieve plant has one of the largest single clinker kilns in the world.

US: Mississippi Lime has declared a force majeure event due to flooding by the Mississippi River caused by ‘significant’ precipitation in the central US. The flooding has impacted the lime producer’s distribution and supply capabilities. This is expected to cause delays in supplying products to customers and will incur additional costs that it will pass through as a surcharge. The company added that, despite this, the flooding has not affected production.

Flooding on the Mississippi River forced the closure of Mississippi Lime’s barge loading facilities in early May 2019 and an alternate barge loading facility later in the month. The company does not anticipate re-opening its facility until the flood waters recede to a safe level, possibly in late June 2019. In the meantime the closure of flood gates near the company’s Ste Genevieve, Missouri unit has forced the company to use an alternate rail route with reduced shipment capacity, additional transit time and higher cost for both inbound and outbound shipments. Mississippi Lime anticipates resuming rail shipments in late June 2019, depending on weather conditions.

US: The Environmental Protection Agency (EPA) has awarded Energy Star certification to Buzzi Unicem USA’s plants at Chattanooga in Tennessee, Festus in Missouri, Maryneal in Texas and San Antonio in Texas. This certification is awarded to a facility for superior energy performance in comparison to similar plants. This marks the 10th consecutive year that the Chattanooga, Festus and Maryneal plants have received certification and the fifth consecutive year for the San Antonio plant.
