Abstract
The superior machining of waste involves their reuse as raw material for new products. In the research there was aimed to improve the known technological process to reduce costs and increase productivity. Thus, the process was redesigned by introducing new technologies related to shredding of waste respectively de-vulcanization in autoclaves. Shredding technological process has been redesigned by using shredding tools, ultrasonic activated in order to increase productivity, durability of these tools respectively the decrease of energy consumption. There were also conducted researches on the autoclave vacuum after rubber de-vulcanization which allows an increase of reclaimed rubber qualities.
Keywords: composite waste machining; rubber; ultrasound; de-vulcanization
