Feedstock recycling of rubber a review on devulcanization

During the grinding process, which typically yields granulate of a few mm or below, the temperature can be lower than the glass transition temperature (i.e. cryogenic grinding) of the polymers in the tires or close to room temperature. The resulting powder can be used as a filler e.g. in fresh tyres, and added just in a low amount.
