| Abstract | Each year a large amount of worn synthetic and natural rubber is discarded. Due to the complex three-dimensional structure, recycling, and degradation of rubber by natural processes are proven complicated. While waste rubber disposal has become a problem globally, the current rubber waste management measures are found to be inadequate. Rubber devulcanization or degradation produces rubber with broken crosslinks or broken main chain polymer, respectively. The devulcanized or degraded rubber can be reused, recycled as a new product, or used for energy recovery in various applications. The current review addresses the problems in rubber waste management and aims to provide detailed insight into alternatives to manage rubber waste through thermal, mechanical, physical, chemical, and biological methods. The advantages, disadvantages and bottlenecks present in each method is discussed. This review also presents the circular economy establishment on rubber in current and future prospect. This review concluded that while more research on technical, economic, and environmental aspects is needed, the methods discussed in the review lead the way for a more sustainable framework in rubber waste management.
