True cryogenic grinding is a different process designed to exploit the tendency of many materials to become brittle at low temperatures. In grinding plastics and rubbers, for example, the stresses needed to break up the material are dissipated by relaxation. As a result, plastics need 10–100 times as much

Cryogenic grinding involves cooling a material below its embrittlement temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture.
