Abstract：The rapid growth and widespread consumption in the automotive industry have led to a surge in waste tire generation. Waste tires are a significant concern due to their environmental and resource impacts. Improving the recyclability and eco-design of tires is essential to address this problem. This study aims to tire recyclability using an innovative model based on statistical entropy and a hierarchical determination rule. This rule considers the differences between the tires' original state and their post-recycling state, as well as the predominant treatment and disposal methods. We applied this model to assess five different tire applications. The results indicate that tire recyclability ranges from approximately 82% to 93%, with the highest recyclability found in truck tires, followed by car tires, van tires, bus tires, and off-road vehicle tires. These findings can inform the design of tire recycling processes and energy recovery efforts. The developed recyclability method may significantly contribute to the eco-design of tires and promote energy saving and emission reductions in the tire industry.
