Yes, ceramic fiber products can be recycled. Recyclers can process used ceramic fibers to reclaim fibers for reuse in new products or to create other valuable materials. The recycling process typically involves shredding, cleaning, and re-carding the fibers. Recycled ceramic fibers are often used in lower-temperature applications or as additives in cement and other construction materials. However, it's important to note that the recycling process and the usability of recycled fibers depend on the specific type of ceramic fiber and its contamination level.
