The most promising technology for a high quality recycled rubber is devulcanization. In this process, in the ideal case, only the sulfur crosslinks will be broken, resulting in a processable rubber with properties comparable to the ones of the feedstock.
An extensive study was done to devulcanize different types of feedstok and determine the quality of the resulting products. The feedstock was varied in terms of age of the tires, single tire parts versus whole tires, particle size of the granulated tire rubber, carbon black versus silica filled rubber, and different silica-silane combinations. In terms of the devulcanization process, pre-treatment of the ground tire rubber, type of process as well as processing time are discussed. Besides, the analysis of the recycled rubber will be discussed.
Finally, the sum of these considerations will result in an overview of the challenges and chances of devulcanization and reuse of whole tire rubber.
