US: Cemex USA has commissioned a new 225t cement unloader for handling dry bulk materials from ships at the Port of Palm Beach in Florida. The port says that the producer invested US$7m in the equipment. It is decorated with a mural of a manatee cow and calf, dedicated to local conservation charity Friends of Manatee Lagoon.

US: The Environmental Protection Agency (EPA) has announced that 10 cements plants have received its Energy Star certification in 2022 from a total of 86 manufacturing plants across all industries. The certification is awarded to the top 25% performers in energy efficiency in each sector. The EPA cited examples of how Titan America’s Troutville plant in Virginia and its Medley plant in Florida had converted production to Portland Limestone Cement (PLC), and achieved a 12% reduction in electricity use and an 18% reduction in CO2 emissions, respectively, thanks to improved energy management. It also mentioned Cemex’s Miami plant in Florida, which increased its energy performance in 2022 by modifying a finish mill, optimising the ball charge on the largest mill and identifying and correcting potential energy losses while also increasing the production of PLC.

Cement plants awarded the Energy Star certification in 2022 include: Drake Cement’s Paulden plant and Salt River Materials Group’ Clarkdale plant in Arizona; GCC’s Pueblo plant in Colorado, Cemex’s Miami plant and Titan America’s Medley plant in Florida; Argos USA’s Harleyville plant in South Carolina; GCC’s Rapid City plant in South Dakota; Buzzi Unicem USA’s Chattanooga plant in Tennessee; Titan America’s Troutville plant in Virginia; and Ash Grove Cement’s Seattle plant in Washington.

US: Cemex USA and RTI International have secured US$3.7m in funding from the US Department of Energy for their Balcones cement plant amine technology carbon capture study. The plant in New Braunfels, Texas, will trial RTI International's non-aqueous solvent (NAS) system, licensed by energy and technology company SLB. Resources News has reported that the system will have a CO₂ capture capacity of 670,000t/yr. RTI International's principal project investigator Vijay Gupta said that NAS capture has a 30 - 40% lower energy penalty than preceding solvent-based technologies.

Cemex USA president Jaime Muguiro said "We remain committed to exploring technologies that can help us meet our targets as we build a more sustainable future. We are striving to cut emissions across all our operations, and this study with RTI International is one of the many steps Cemex is taking to achieve our objectives."

US: A coal pile collapse at Cemex USA's Knoxville, Tennessee, cement plant killed one worker at the plant earlier in November 2022. Local press has reported that Thomas Mitchell, aged 21, died at the scene.

Cemex says that it is cooperating with an on-going investigation into the disaster.

US: The Board of County Commissioners of Boulder, Colorado, has denied Cemex USA’s application for a 15-year extension to its Dowe Flats quarry mining licence, following its expiry on 30 September 2022. Commissioner Claire Levy cited dust, traffic, noise and disturbances to wildlife as reasons behind the decision.

Cemex USA’s nearby Lyons cement plant has previously relied on the quarry for the supply of 760,000t/yr of limestone.

US: Cemex USA has applied for a permit to continue mining at Dowe Flats to support operations at its integrated Lyons cement plant in Colorado. It has asked the Boulder County Community Planning and Permitting department to allow it continue mining for 15 years until 2037, according to the Daily Camera newspaper. It then says it will close the cement plant. Its existing mining permit will end later in 2022.

US: Cemex has increased production of Portland limestone cement (PLC) at its Lyons plant in Colorado. PLC is expected to become the plant’s primary product by the summer of 2022. The blended cement has been produced at the site for over 15 years. However, Cemex says it is growing production to meet the company’s carbon reduction goals and meet increased demand for lower carbon materials.

Cemex USA has also increased PLC production at its plants in Brooksville, Florida, and Demopolis, Alabama. The start of PLC production or further increases is planned for other cement plants later in 2022.

US: Cemex USA has begun selling Portland limestone cement produced at its Brooksville, Florida, and Demopolis, Alabama, plants across the Southeastern US. The producer says that the cement retains the durability of ordinary Portland cement or is more durable while reducing CO₂ emissions by 10%. Cemex USA aims to increase its PLC production at the plants, and possibly to begin producing it at other US cement plants, in early 2022.

President Jaime Muguiro said "At Cemex, we acknowledge that climate action is one of the most important issues facing our world, and we are committed to being part of the solution. Our company has ambitious emission-reduction targets, and by offering lower carbon products that deliver brilliant performance like PLC, we can continue to work toward those goals while encouraging customers to join us in the journey."

US: Cemex USA has sold its headquarters in West Palm Beach, Florida for US$13.4m. The South Florida Business Journal newspaper has reported that the company will vacate the property in early 2022. It will relocate to a nearby smaller office. Cemex USA has occupied its current headquarters since 1983. According to sources quoted by the newspaper, it no longer requires the 20,000m² space due to increased rates of remote working by staff.

US: Cemex USA has upgraded two Florida cement terminals, the Pensacola and Palm Beach terminals, at a cost of US$8m. The upgraded terminals will serve to increase Cemex USA’s cement supply to the region through marine shipments from its global operations. The Palm Beach terminal is also involved in the distribution of assorted cementitious materials including granulated blast furnace slag (GBFS) and fly ash for cement production.

USA executive vice president Matthew Wild said “Florida is growing rapidly, and Cemex’s strong network makes our company well-positioned to implement supply chain and operational enhancements to meet the high demand for building materials in Florida and beyond.” He added “On the cement side, increased demand has outpaced supply at times, and we expect our supply chain enhancements to help alleviate that issue.”
