Abstract. Cryogenic grinding represents an opportunity for expanding recycling capabilities to a broad range of compounds. Many materials that can be reduced to a powder by conventional coarse grinding can be reduced more efficiently by using a super cold agent such as liquid nitrogen at 320/sup 0/F to embrittle plastic or rubber polymers before grinding.
