Heidelberg Materials has converted its Indiana cement plant to a slag grinding facility in response to market demand for sustainable products.
Heidelberg Materials stopped producing Portland cement in the facility, located in Speed, Indiana, last year. This followed the company’s opening of a new cement plant in Mitchell, Indiana, last year, which it described as “state-of-the-art.”
The manufacturing site in Speed has been modified to produce slag cement from domestically sourced slag granules. Replacing a portion of conventional Portland cement with slag cement in a concrete mix helps reduce environmental impact.
The Speed site, which has an annual grinding capacity of more than 400,000 tonnes, also serves as a distribution hub for cement produced at the Mitchell plant and a wide range of specialty cementitious products.
Heidelberg Materials extends von Achten’s term
“The adjustments made at the Speed plant reflect Heidelberg Materials’ strong commitment to achieving net-zero emissions in North America,” the company said in a statement.
“Heidelberg Materials follows an ambitious global climate strategy, aiming to generate 50% of its revenue from sustainable products that are either low-carbon or circular by 2030. The company plans to achieve net-zero emissions by 2050 at the latest.”
Recently, the company was selected by the US Department of Energy for funding of up to US$500 million to advance industrial-scale carbon capture, transport, and storage at its Mitchell cement plant.
