Cryogenic grinding is an innovative process that involves grinding plastic materials at extremely low temperatures to prevent melting. By subjecting the plastic to sub-zero temperatures, typically using liquid nitrogen or carbon dioxide, the material becomes brittle and can be easily ground down into a fine powder.
