Sustainable development of waste tires recycling technologies – recent advances, challenges and future trends

Dynamic development of the automotive industry and the growing number of various vehicles generate demand for the global production of tires. Simultaneously, high performance of tires cause serious problems with further management and recycling of end-of-life tires. Therefore, searching for novel, environmentally-friendly and cost-effective rubber recycling methods is currently one of the biggest environmental challenges in the 21st century. This work aims to report the recent progress in sustainable development of waste tires recycling technologies. A special attention was focused on current advances in waste tire rubber grinding technologies; ground tire rubber treatment methods and characteristics of ground tire rubber and reclaimed rubber. Moreover, the main challenges affecting the future trends of the industrial application of waste tire rubber recycling technologies are also discussed.
