2025 ASC Annual Convention & EXPO – Jacksonville, Florida
April 9, 2025
Leaders from MLC and its parent company, HBM Holdings, broke ground on a historic investment at MLC’s Bonne Terre, Mo. location for dolomitic lime.
MLC is completely refurbishing the site, a project that will be crowned with the commissioning of a new world-class, sustainable kiln in 2026. The company has also invested in new safety equipment, work areas and logistics capabilities.
“This project represents our commitment to excellence in lime manufacturing,” said Paul Hogan, MLC president and CEO. “It marks one of the most significant capital investments in our history and generates value across our stakeholder groups — improving quality for our customers, sustainability for our communities and a safer, more enjoyable workplace for our team members.”
Acquired from Valley Minerals in 2022, MLC’s Bonne Terre operation manufactures dolomitic lime offerings, which are essential components used in steel and glass manufacturing. Seated in Southeast Missouri, the operation is strategically located to serve domestic metal and glass manufacturers, especially as new steel plants come online in the Southeastern and Midwestern U.S. within the coming years.
The new vertical-shaft kiln will improve production efficiency and reduce carbon emissions per ton manufactured. Other improvements at the site include upgrades for safety equipment and construction of a new rail connection, office building, quality lab and employee break and locker areas.
“This project is a milestone for our strategic vision: to be the leading global provider of lime solutions with an unwavering commitment to safety, sustainability and service. We are investing capital across all our sites in pursuit of that vision, reinforcing our position as industry leaders in responsible lime manufacturing,” Hogan said.
"This project...marks one of the most significant capital investments in our history and generates value across our stakeholder groups — improving quality for our customers, sustainability for our communities and a safer, more enjoyable workplace for our team members."
