Opportunities and challenges facing the development of the comprehensive utilization of waste tire recycling machine in China 1

At present, my country's comprehensive utilization of waste tire crusher industry has achieved great development, especially in the production and application of reclaimed rubber, my country has walked in the forefront of the world. China's production of recycled rubber accounts for 73% of the world's total. Chinese recycled rubber manufacturers are located in all provinces, cities, and autonomous regions in China, except for Macau and Hong Kong. But at the moment, the comprehensive utilization of waste rubber industry, like other industries, is facing the overall pressure to upgrade the industry.

In 2017, the waste rubber comprehensive utilization industry actively responded and actively implemented national policies. The industry took the initiative to carry out green transformation to achieve clean production and achieve clean and environmentally friendly production processes. The branch organized the revision of the standard of environmentally friendly reclaimed rubber, and provided a standard guarantee for the promotion of the application of recycled products. After the environmental protection of the production process is realized, the environmental protection of the product will soon have a standard basis.

In 2017, relevant national ministries and commissions successively issued a series of regulations and provisions to promote the development of industry standards, which pointed out the direction for the next development of the industry. In 2018, the dual tasks of environmental protection and resources undertaken by China's waste rubber comprehensive utilization industry will become more arduous. The development of the industry and enterprises will accelerate the realization of standardized and green development.

Recycled rubber is the main way to use waste rubber. At present, the main ways of using waste rubber in my country are tired retreading, recycled rubber, rubber powder, and thermal cracking. Among them, recycled rubber has become the third indispensable rubber resource in China's rubber industry after natural rubber and synthetic rubber. The direct application of rubber powder is an internationally recognized environmentally friendly and resource-based harmless processing and utilization method for waste tires. Reclaimed rubber has a 160-year history of development as a resource-oriented polymer material for the recycling economy. Calculated by rubber hydrocarbons, each ton of reclaimed rubber can replace 45% of natural rubber or synthetic rubber and has a special resource status.

Reclaimed rubber production is the main force in the utilization of waste rubber in our country, and reclaimed rubber itself has a good cost performance. More than 70% of the world's reclaimed rubber production is produced in China. Chinese reclaimed rubber manufacturers are located in all provinces, municipalities and autonomous regions in China except Macau and Hong Kong. The source of waste rubber is mainly waste rubber products, that is, scrap tires, tires, hoses, tapes, rubber shoes, industrial sundries, as well as leftovers and waste products produced by rubber enterprises. The raw rubber consumption of tire products accounts for about 65% of rubber consumption, and the other 35%. 70% of the total waste rubber comes from scrapped automobile tires.

According to incomplete statistics, the output of recycled rubber in China in 2017 reached 4.8 million tons, an increase of 5% year-on-year; the output of rubber powder reached 700,000 tons, an increase of 8% year-on-year; the main material for the production of recycled rubber was rubber powder, and 4.6 million tons of recycled rubber required With 4.05 million tons of rubber powder, together with 700,000 tons of directly applied rubber powder, the output of rubber powder reached 4.75 million tons. China is not only the world's largest producer of recycled rubber, but also the world's largest producer of rubber powder.
