A two-stage process for recycling of vulcanized rubber was proposed. In the first stage, the vulcanized rubber was shredded into granulates, and then the granulates were pulverized into fine particles using a single screw extruder in the solid state shear extrusion (SSSE) process. In the second stage, the produced rubber powder was compression molded to produce new items.
