    An effective yet cheaper SSSE process was developed using a single screw extruder by Arastoopour in his patented work and Bilgili et al. also used the single screw version of SSSE in their work and identified the effect of different dependent and independent variables on the pulverization of rubber granulates using SSSE. 15 21 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.
