In a statement, the company said the lightweight monolithics facility, which will be built at its Fulton, Mo., rotary kiln complex, will expand production capacity by approximately 60%. The facility will include a new furnace and automated robotic packaging and material handling systems.

“By expanding our lightweight monolithic capacity and leveraging our extensive distribution network, we’re positioning ourselves to better serve our customers across the Americas. The project is also an opportunity to further strengthen our presence and positive impact in Missouri, where we have been operating for over 100 years,” said of Calderys Group’s Ross Wilkin, senior vice president of the Americas region. HWI is part of the Calderys Group. 

HWI said the new facility will absorb Greenlite aggregate production from the Minerva plant, which will cease operations in July 2025. The new site provides access to local, high-quality clay reserves, allowing HWI to increase the production of its Greenlite aggregate-containing products, the company said. 

“This investment demonstrates our commitment to meeting our customers’ evolving needs and reinforcing our market leadership position,” said Calderys Group president and chief executive officer Michel Cornelissen.
