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.
