US: Queens Carbon has secured US$10m in seed funding to scale up production of its novel cement and supplementary cementitious materials (SCMs). The start-up will build a 2000t/yr demonstration plant at strategic partner Buzzi Unicem USA's Stockertown, Pennsylvania, cement plant. The plant will demonstrate Queens Carbon’s low-energy Q-Reactor technology, which employs novel hydrothermal chemistry, with the help of steam and pressure, to combine standard cement feedstocks into carbon-neutral hydraulic cement and SCMs. The company’s flagship product, Q-SCM, is capable of replacing up to 50% of cement in concrete mixes. Queens Carbon says that it will now also begin preparations for its first full-scale commercial plant.

Buzzi Unicem USA was among investors in the seed funding round, led by Climate technologies investor Clean Energy Ventures, with participation from fellow venture capital firm Plug and Play.

Queens Carbon CEO Daniel Kopp said "With support from Clean Energy Ventures, Buzzi Unicem USA and the US Department of Energy, we're building next-generation technology and assembling the creative talent needed to drive industry revenues to move cement innovation forward and significantly reduce CO₂ emissions from cement production, all without a green premium."

Luigi Buzzi, Chief Technology Officer at Italy-based Buzzi, said "We know that achieving our goal of net-zero carbon emissions by 2050 demands forward-thinking solutions to enhance both our operations and our environmental performance.”

US: Buzzi Unicem has blamed a late tax payment in Pennsylvania on an accounting error. The cement company made the US$18m payment five months late, in May 2024, according to the Express Times newspaper.  The issue was highlighted by a lien filed in December 2023 in Northampton county civil court. Stockertown cement plant manager Rad Slavov clarified that the payment was timely but misallocated. He said "The company is financially strong and able to meet its obligations.”

US: Shipments of cement, including imports, in the US and Puerto Rico fell by 2.5% year-on-year to 80.7Mt in the first nine months of 2023 from 82.8Mt in the same period in 2022, according to data from the United States Geological Survey (USGS). Shipments fell in most states with the exception of Texas and Pennsylvania. The USGS estimated that, in September 2023, 98% of all blended cement shipments were of Portland Limestone Cement. Turkey was the biggest exporter of cement to the country during the reporting period at 6.3Mt followed by Canada, Vietnam, Greece and Mexico.

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.

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.
