100 Continental Cement workers go on strike

28 February 2023

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.”

Buzzi Unicem USA to switch to Portland Limestone Cement production by the end of 2022

01 June 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.

LafargeHolcim US and Geocycle receive first delivery of coal ash under 6Mt recycling contract with CenterPoint Energy

17 November 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.”

LafargeHolcim US reveals more detail on carbon capture study at Ste. Genevieve cement plant

03 November 2021

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.

Mississippi Lime declares force majeure event due to flooding

04 June 2019

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.
