Huber Engineered Materials, a division of J.M. Huber Corp., launched ReCal platinum calcium carbonate for use as a component in building materials to generate various green building credits and in other demanding applications where certified post-consumer content is required.
Huber said ReCal Platinum is 50 percent by weight post-consumer content (third-party verified) with the remaining 50 percent post-industrial content (third-party verification pending) produced by a proprietary re-milling process (patent pending).
It is a light gray color milled to a consistent median particle size and topcut. Two ReCal Platinum Calcium Carbonate products are offered—ReCal Platinum 8 and ReCal Platinum 20—which are milled to an 8- and 20-micron median particle size, respectively.
