Abstract
Disclosed herein is an improved pan agglomeration process for forming porous absorbent particles suitable for use as an animal litter. The process eliminates the need for a pre-wetting step, while forming agglomerates that are up to 65% lighter in weight than the raw material feed. In addition, the agglomerates can incorporate performance-enhancing actives, such as odor-controlling carbon.
