Recently, some media appeared that "recycling rubber companies face operational difficulties, the industry calls for waste tire imports imminent," and "imported scrap tires call for another surge" and other articles. The author believes that this is inconsistent with the current state policy, which is not conducive to the development of the recycling economy in the rubber industry, and it is also not conducive to the healthy development of the waste rubber comprehensive utilization industry. The relevant leaders of the National Development and Reform Commission have also stressed that China’s comprehensive utilization of resources must stand on the basis of safeguarding national interests and must proceed from the overall situation.

As everyone knows, waste rubber is a polymer that is hardly degradable, especially waste tires have strong heat resistance, mechanical resistance, long-term outdoor dumping, not only occupy a lot of land, but also very easy to breed mosquitoes, infectious diseases, at the same time And easy to cause fire. In foreign countries, Japan, Canada, and the United States have all caught fire due to the accumulation of scrap tires. In China, it is no exception that reports of large-scale fires caused by the accumulation of scrap tires are commonplace every year. In addition to the huge losses of property suffered by companies, the environment is also seriously damaged.

The disposal of scrap tires is still a big problem in the world. The developed countries have historically adopted preferential policies such as tax relief and financial subsidies for the disposal of used tires. For example, although the legislation in the United States is different, the policies for disposing of used tires are basically the same. Each tire is subsidized between US$3-5. The Canadian government provides a subsidy of US$60 per ton of used tires, and Europe treats one ton of used tires per subsidy. 140 euros; Taiwan's Taiwan Province, handling 1 ton of EPD subsidy of 3,200 yuan each, Hong Kong's handling of 1 ton of EPD subsidy of 1,700 Hong Kong dollars, etc., indicating that the industry is a policy encouraged by the public welfare industry.

In the second half of 2010, the China Rubber Industry Association organized enterprises to visit the United States and Canada to inspect waste tyres. Each state in the United States has regulations on the disposal of used tires. Through joint efforts, the stock of used tires in the United States has been reduced by many, and more than 90% of used tires have been recycled, mainly for the use of heat energy and for the production of rubber powder and reclaimed rubber. With regard to the social responsibility of used tires, the states have passed legislation through consultation. From tire manufacturers to tire distributors, including importers, they all pay dispose of used tires in different proportions.

The president of the Canadian Rubber Association, Glenn Maidment, called the waste rubber recycling industry an "environment for the survival of 43 million Canadians living in Canada, which is home to 9.97 million square kilometers." Raising waste rubber recycling to such a high level is worth thinking about. In addition to economic subsidies, Canadian provinces also promote the use of waste tire end products through various media, encourage everyone to use rubber products produced from scrap tires, and provide loans for waste tire processing companies and final rubber product manufacturers to enable production technology. More advanced, the final product is more applicable and environmentally friendly.

Similarly, France has prohibited landfills, discarded and burnt used tires since the 1980s, and at the same time supported tax breaks, subsidies, and other methods to support the start-up and operation of waste tire recycling companies and encourage research and development in this area. A number of used tires were refurbished and reused, as well as the production and application of waste rubber recycled materials.

In China, the "Circular Economy Promotion Law" promulgated by the state on January 1, 2009 made it possible to follow rules and regulations for the recycling of waste rubber. China is a big country for tire production and consumption. In 2009, China produced 233 million waste tires and weighed about 8.6 million tons. This is a very large number. How to follow and implement the 3R principle of "resources, reduction, harmlessness, and remanufacturing" of used tires has become an urgent problem to be solved. The National Development and Reform Commission predicts that if 233 million used tires are completely recycled, it will be equivalent to 5 years of natural rubber production in China. At present, the utilization rate of discarded tires in China is around 80%, and there is a long way to go for recycling. Recycling should first of all purify the environment of its own country. Therefore, the focus of the use of used tires must be placed in the country.

Liu Zengyuan, head of the Expert Group of the Waste Rubber Comprehensive Utilization Branch of the China Rubber Industry Association, pointed out that China's waste rubber comprehensive utilization industry must use two figures for assessment. First, what is the industry's per capita GDP contribution rate? Second, the energy consumption per million yuan of GDP in the industry is How many. Reclaimed rubber and rubber powder are still low-value recycled products. At present, the industrial production value of plastic powder is RMB 1000kWh or more in the waste rubber processing process, and the industrial production value of recycled rubber is RMB 1500kWh or more. The comprehensive energy consumption per unit product is still very high. However, it is also necessary to eliminate environmental pollution caused by scrap tires and to restore it.

Therefore, from the comprehensive perspective of environmental protection, resources, and energy consumption, it is incumbent to deal with domestic waste tires, but disposing of used tires out of the country is not worth the candle. It is necessary to prohibit the transfer of used tires from abroad to China, avoid increasing the domestic processing volume, prevent foreign waste tires from polluting our country's environment, and reduce excessive energy consumption. After all, the property of waste tires is solid waste, which will pay for energy consumption and environmental risks during the process, at a costly price.

In addition, the advantage of cheap labor in China is gradually losing, which is already evident in China's waste rubber comprehensive utilization industry.

Since the beginning of 2009, China has listed the recycling of used tires as a key development area, and has fully supported the recycling of used tires in China in terms of formulating laws and regulations, tax incentives, and providing discount loans. However, if the companies enjoying the above-mentioned preferential treatment deal with waste tires of other countries, they will violate the original intention of the country. There are many things that China needs to do, and it is far from having enough financial resources, environment, and energy to help other countries deal with waste. Therefore, the production of recycled tires for the production of reclaimed rubber, rubber powder and tires is more harm than good. Waste tires can not be imported, otherwise the consequences could be disastrous.

At present, China should further standardize the harmless recycling of waste tires and the use of environmentally-friendly systems, set industry thresholds, crack down on oil refining, and promote the collection and compensation mechanisms for used tires. The concept of “safety, efficiency, environmental protection, and energy conservation” should influence Next, realize and complete the environmental protection and resource history mission of comprehensive utilization of waste rubber in China.
