The harmless and recycling treatment of the waste rubber tires is an important measure and means for reducing environmental pollution, keeping ecological balance and maintaining human health. At present, the main modes for treating and utilizing the waste rubber tires in China are as follows: simple original shape utilization, tyre retreading, energy supply as fuel, extraction of valuable chemical products after thermal cracking and the like.
