Holcim US to Increase Flagship Capacity, Reduce Emissions

Holcim US announced a $100 million investment in its Ste. Genevieve, Mo., cement plant – the largest cement-producing facility in North America and one of the most technologically advanced and environmentally efficient facilities in the world. 

The capital investment will expand the flagship plant’s current production and logistics capabilities. The installation of a fifth vertical cement grinding mill will enhance processing and allow cement production capacity to increase by more than 600,000 metric tons while reducing net CO2 emissions by more than 400,000 tpy.

A new mineral component addition system will further reduce clinker factor and increase circularity by adding fly ash or other mineral components to cement produced. Planned logistic improvements include an expansion of the plant’s current rail-loadout capabilities to better serve growing markets in the upper Midwest.

“With an emphasis on achieving the highest levels of environmental performance and operational efficiency, Ste. Genevieve has been the leader in U.S. cement manufacturing since it was built in 2009,” said Toufic Tabbara, North America region head. “This investment will ensure we maintain that leadership in supporting the sustainable growth of our nation’s infrastructure and residential construction while accelerating net carbon reduction across the built environment.”

Holcim said with permits and government approvals in hand, the new fast-track expansion project begins construction in 2024 and will be completed in late 2025.
