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: Roanoke Cement, part of Titan America, has held a ground-breaking ceremony for an expansion at its Chesapeake Terminal near Norfolk in Virginia. Council members, other state and local officials and Roanoke Cement team members gathered to launch the project, to build a new US$40m storage dome. In response to increasing demand for low carbon cement, the storage dome at the terminal will provide an additional 70,000t of capacity, tripling the site’s existing storage volume. The Chesapeake Terminal will see expanded truck and rail capacity as well, and the improved terminal will enable the import and distribution of other raw materials needed to produce concrete.

"This important capital improvement is another investment in anticipation of increased construction material demand for infrastructure development and other projects," said Kevin Baird, president of Titan America's Mid-Atlantic Business Unit, which includes Roanoke Cement. "Expanded storage and marine terminal upgrades permit us to make low carbon cement available for construction needs all over the region."

The company expects the expanded facility to be completed by the end of 2023, in time for the region’s 2024 construction season.

US: Titan America plans to spend around US$37m towards expanding its Norfolk terminal in Chesapeake, Virginia. The plans at the terminal, run by subsidiary Roanoke Cement Company, include building a 70,000t dome, enlarging truck and railway capacity and enabling the site to import and distribute raw materials such as fly ash, slag and aggregates. At present the unit has a bulk storage capacity of 35,000t. Titan says that the upgrade will enable it to meet growing demand for its products in the Mid-Atlantic region. The project also follows a similar investment in a 70,000t dome currently under construction at Titan's import terminal in Tampa, Florida.

"The major expansion and modernisation of these two marine terminals is another important step toward meeting fast-growing demand for our products and services in critical infrastructure, commercial and residential projects in our communities," said Bill Zarkalis, president and chief executive officer, Titan America.

The dome and associated expansion projects are scheduled for completion in 2023.

US: Charah Solutions has been awarded a marketing contract by Dominion Energy for the beneficiation and utilisation of up to 8.1Mt reclaimed ponded coal ash at its Chesterfield Power Station in Chester, Virginia. The contract will run from 2021 until 2032. It follows local state legislation requiring the power company to remove coal ash from sites at the Chesterfield Power Station within 15 years.

As part of the agreement, Charah Solutions will install processing and transportation infrastructure in 2021 to facilitate rail transportation of the ash from Chesterfield Power Station to cement kiln feed markets. The beneficiated ash product will replace other currently utilised virgin raw materials in the production of Portland cement at multiple cement kiln locations in the eastern US for the next decade and beyond, and help supply the growing demand for concrete in the construction industry.
