Holcim (US) has completed a US$96m upgrade on its Hagerstown plant, Maryland. The facility has existed for over 100 years and according John Stull, CEO of US operations for LafargeHolcim, the latest improvements "really should help this plant to serve the community for another 20 to 30 years.”

The project, during which the plant remained operational, took two years to complete and complies with federal environmental regulations. Oliver Terver, Hagerstown plant manager, spoke of the company’s environmental principles: "We care about operating a facility that is environmentally sound and responsible. Investing in the environment is critical for the health and long-term viability of the communities where we operate.”

The upgrade has cut NOx emissions by more than 60 per cent and SOx output by about 50 per cent, according to a company press release. Particulate matter emissions have been reduced by 75 per cent. The upgrade has also improved the efficiency of the Hagerstown plant and boosted production by about 0.2Mta.

The Hagerstown plant has contributed to projects including the reflecting pool at the Lincoln Memorial, Washington, DC, the Woodrow Wilson Bridge and runways at Washington Dulles International Airport.
