Discussion on Tire Retreading and Reuse Technology

Abstract China has basic state policies of developing circular economy and promoting the reuse of waste materials. They are also regarded as important guarantees for the sustainable development of mankind. The recycling of used tire resources has gradually become a consensus among people as a sunrise industry. Countries all over the world attach great importance to the retreading and reuse of used tires, especially in developed countries who have taken used tires as an important industry to save rubber resources. Tire retreading is a way of recycling resources, which can save rubber raw materials, solve the environmental pollution of waste tires, and make full use of the value of tires. There is no ‘three-waste’ emission during prevulcanization retreading of used tires. It is a green environmental protection industry, which not only can save a lot of rubber, steel wire, petroleum energy and other resources, but also can realize the reduction, reuse and recycling of used tires. Tire retreading is an active way to recycle used tires, it is regarded as extension and processing reuse of the tire industry. They are of positive significance for promoting the comprehensive utilization of resource conservation, transformation of economic growth mode and sustainable development. The characteristics, technological process of tire retreading technology, current situation and development trend of retreading tire are discussed comprehensively in the paper.
