Cryogenic grinding technology has been used in the waste recycling industry to produce rubber crumb since the early 1990s. The main advantage is that when liquid nitrogen (LIN) is used to cool the material to cryogenic temperatures, it becomes more brittle. This means that less energy can be used to easily break it into small particles.
