The Portland Cement Association, representing America’s cement manufacturers, announced the winners of its Energy and Environment, Chairman’s Safety and Safety Innovation Awards at its 2024 Cement Fly-In in Washington, D.C. The awards recognize PCA member-company teams who excelled in implementing new energy and environmental initiatives and those who went above and beyond to enhance overall, on-the-job safety at America’s cement plants.

“Holding this awards event right before teams of industry leaders head to Capitol Hill is a great motivator because it highlights excellence in PCA’s top priorities — safety and environmental initiatives — which will get us to carbon neutrality,” said Mike Ireland, PCA’s president and CEO. “Having plant workers here to accept their awards really adds to the fly-in experience, as they are the boots on the ground for this industry and it is their innovation and their commitment to their co-workers that enables all of America’s cement companies to thrive.”
