Cemex has said six of its cement manufacturing plants have earned the US Environmental Protection Agency ENERGY STAR® certification.

The recognition of Cemex USA's plants in Brooksville (FL), Miami (FL), Clinchfield (GA), Fairborn (OH), Louisville (KY) and Victorville (CA) demonstrates that these facilities perform among the top 25 per cent of similar US facilities for energy conservation.

This year marks the eighth consecutive year of certification for the Clinchfield plant, an achievement realised by only one other cement plant in the US, the fourth consecutive certification for the Miami plant, the third for the Brooksville, Victorville and Fairborn plants and sixth year for the Louisville plant.

Throughout the year, all of the recognised plants put into practice the energy efficiency principles established by the ENERGY STAR® Guidelines for Energy Management developed by EPA.

"Cemex is committed to sustainable practices throughout our operations, including energy efficiency," said Karl Watson Jr, president of Cemex USA. "We are honoured to again be recognised by the EPA and Energy Star for our commitment to sustainable practices."
