The future isn't written... it's built.
And it's built right here in Ste. Genevieve.

How often do you think of cement and concrete? And yet, everywhere we look, we see the value this building product brings to our lives — our homes, schools, the roads we drive on and the buildings where we work.

The American landscape is built with cement. Holcim’s Ste. Genevieve cement plant is iconic as the most technologically advanced, as well as the largest, in the United States. One in five building projects in the U.S. contains Ste. Genevieve-produced cement because of the access our plant has to America’s river system, including the Mississippi River on its eastern border.

Our Holcim employees are our family. They live in the surrounding areas of Ste. Genevieve and Jefferson counties and are the backbone of our success. We are humbled to be a part of the Ste. Genevieve community and look forward to continuing to grow together.

Plant Manager

About Us
Contact Us


Holcim and our Ste. Genevieve plant are committed to being good corporate citizens. We take great pride in community. When the Holcim Ste. Genevieve plant was built, we worked with Ste. Genevieve County to create an alternative to traditional property taxes that saw more than $54 million invested in our community between payments in lieu of tax and contributions to local community foundations. With the expiration of that agreement in December 2020, we are in discussions with the county assessor to ensure Holcim property is classified properly so that it may be assessed fairly. As one of Ste. Genevieve’s largest employers, we are committed to paying our fair share — we know the investments we are making will have a positive effect on the friends and families of our employees.

11th Annual Household Waste Collection and Recycling Day

The 11th annual household hazardous waste collection event held Saturday, Dec. 11 was a successful community effort with 5.9 tons of hazardous waste, 1.7 tons of non-hazardous waste and 30.7 tons of electronic waste diverted from the local landfill. Partners involved in the collection included the Holcim Ste. Genevieve cement plant employees, Missouri Department of Natural Resources, several recycling vendors, and the Ste. Genevieve Recycling Center.

Environmental Commitment

Our state-of-the-art plant is one of the most environmentally efficient in the world and uses the latest environmental control technologies. For example, energy efficiencies at the Ste. Genevieve cement plant result in CO2 emissions (carbon dioxide) that are approximately 10-15 percent less than other cement manufacturing sources.


Alternative Fuels Can Help Lower Our Carbon Footprint

Communities and businesses across the U.S. are seeking ways to improve the environment by applying new methods for reducing their environmental impact. Items such as used tires, plastics, textiles, carpet, upholstery and off-spec products all too often find their way into landfills, rivers, streams and creeks. But that doesn’t have to be our story. We can do better. Some of these materials can be beneficially reused as alternative fuels. Click here to learn more.

The Benefits of Using Alternative Fuels & Raw Materials:

  • Completely eliminates materials with no leftover residue or odor.

  • Can reduce emissions from carbon dioxide, sulfur, and nitrogen.

  • Provides a sustainable solution by reducing use of virgin raw materials and fuels.

Putting Safety First

The health and safety of our employees, contractors and those who visit our Ste. Genevieve site is a core value. Safe practices and behaviors are constantly emphasized to achieve a goal of zero harm. To support our safety mindset, we continually monitor our practices and safety events to ensure we are innovative and effective in keeping everyone safe.


Safety is our number one priority in every job.

About Us


Our cement plant, located in Bloomsdale, Missouri was built from the ground up starting in 2006. We began production on July 4, 2009.  Today our plant is still the largest single line kiln in the world and a part of LafargeHolcim's U.S. operations.

The Ste. Genevieve plant employs 244 individuals who support the production of more than 4.5 million metric tons of cement annually. Our cement products include Type I-II Low Alkali and 10 percent raw limestone-added Type IL. Ste. Genevieve cement is distributed to markets along the Mississippi River and its connected rivers.

Our 4,000-acre site contains more than 100 years of limestone supply, and we have set aside 2,000 acres as a conservation area.

The products we produce are used all around the world, and right here in Missouri. You can find Ste. Genevieve cement in the foundations of the places you live, work and play including Ballpark Village, St. Louis airport, and Jefferson College.
