Dec. 4, 2025 - HWI, A member of Calderys, has successfully completed construction of a new lightweight monolithics production facility at its Rotary Kiln complex in Fulton, Missouri, USA. This state-of-the-art plant marks a significant investment in the Calderys Group’s growth strategy for the Americas, boosting HWI’s lightweight monolithics production capacity by nearly 60%. The expansion enhances product availability, shortens lead times for customers, and incorporates advanced technology and automation—including a new furnace and fully 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 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 more than 100 years,” said Ross Wilkin, SVP, Americas – HWI. 

The new facility provides direct access to high-quality local clay reserves, enabling increased production of HWI’s GREENLITE aggregate-containing materials, including the GREENLITE®-45-L family of monolithics and GREENLITE® 115 AR brick.
