China has made significant progress in the reclaimed rubber industry, with annual output reaching 1.45 million tons and securing the top position globally. While this achievement is celebrated, it also raises concerns about the inefficient use of waste rubber, which leads to resource wastage and environmental pollution, undermining the sustainability of the recycling economy.
According to the China Rubber Industry Association, the utilization of waste rubber has steadily increased over the years. In 2005, the production of reclaimed rubber from waste materials reached 1.45 million tons, with a utilization rate exceeding 60%. Despite this, China still lags behind developed countries like the U.S. and Japan, where waste rubber is not only recycled but also used for advanced applications such as rubber powder in construction materials and energy recovery through combustion.
In China, the primary method of waste rubber utilization remains the production of reclaimed rubber. However, the re-use rate is still low due to technological limitations. For example, tire retreading technology is not yet fully developed, leading many tires to be converted into rubber powder or even discarded, causing both resource loss and environmental damage.
Industry experts emphasize that the comprehensive utilization of waste rubber reflects a country’s economic development level. It involves thermal energy recovery, original reuse, and recycling. In China, this process is closely tied to environmental protection and the promotion of a circular economy. Currently, the focus remains on reclaimed rubber, but the industry sees a need to accelerate the development of rubber powder technology and promote deeper processing.
By 2010, the goal is to increase the comprehensive utilization rate of waste rubber beyond 80%. Meanwhile, China has become the world's largest consumer of rubber, with its consumption accounting for more than 20% of the global total. However, domestic rubber resources make up only around 10% of the world’s supply, necessitating large imports of natural and synthetic rubber each year.
Given these challenges, improving the efficiency of waste rubber recycling is crucial for the sustainable growth of China’s rubber industry and its transition toward a circular economy.
