CalStar begins production at two-line, Mississippi masonry plant

CAPTION:The cast stone products are made with CalStar’s proprietary process that incorporates up to 37 percent recycled content and eliminates the need for portland cement; calcium silicate materials, which require energy-intensive autoclaving; or for kiln-firing, typical of traditional clay brick. When measured against portland cement and clay alternatives, each CalStar product requires up to 81 percent less energy to make while emitting up to 84 percent less carbon dioxide.

CalStar Products has begun delivering building and landscape units from a 100,000-sq.-ft., Columbus, Miss., operation—an ambitious satellite to a Racine, Wis., flagship plant opened in 2010.
