The production and application of recycled rubber has become a new force for the comprehensive utilization of waste rubber

with the continuous development of China's rubber industry, the comprehensive utilization industry of waste rubber (including waste tires) has shown a trend of rapid development, especially the production and application of recycled rubber has become a new force for the comprehensive utilization of waste rubber, accounting for more than 80%

the market of reclaimed rubber products is broad.

in 2011, the output of reclaimed rubber in China reached 3million tons, and there were about 1500 reclaimed rubber enterprises. As the main body of waste rubber utilization in China, reclaimed rubber accounts for more than 80% of the total utilization of waste rubber in China and 80% of the total output of reclaimed rubber in the world

The rapid development of recycled rubber industry has solved the problem of recycling waste rubber on the one hand, and alleviated the serious shortage of domestic rubber resources on the other hand. Over the past 60 years, China's reclaimed rubber industry has recycled more than 30 million tons of waste rubber, created a value of more than 80 billion yuan for the society, saved and replaced more than 9 million tons of raw rubber, and made great contributions to solving "black pollution" and developing circular economy in the rubber industry

ensure that the setting out of general flexible packaging manufacturers is accurate. 20 make the actuator plug move quickly to the working position. In 11 years, the number of domestic motor vehicles has reached 225million, including more than 100million vehicles, producing 250million waste tires every year, weighing more than 9 million tons, and the pressure of environmental protection is unprecedented; At the same time, China's external dependence on natural rubber has exceeded 80% for two consecutive years, and the external dependence on synthetic rubber is close to 50%. The contradiction between supply and demand is extremely acute. Therefore, vigorously developing the renewable rubber industry is the choice of blue sky and green water, the need of the national economy and the people's livelihood, and the necessity of national strategic development

the types of reclaimed rubber products in China are diversified, and the scientific and technological content is further improved. At present, China has been able to produce halogenated butyl reclaimed rubber, general butyl reclaimed rubber, EPDM reclaimed rubber, high strength reclaimed rubber, tasteless reclaimed rubber, environmental friendly reclaimed rubber and other major varieties. Recycled rubber is widely used in tire, conveyor belt, rubber shoes and other industries; Recycled rubber is used together with natural rubber and cis-1,4-polybutadiene rubber to make tires, and recycled rubber is used together with natural rubber and cis-1,4-polybutadiene rubber to make shoe soles; Some products can replace 30% - 50% of natural rubber or synthetic rubber

adhere to independent research and development, but the industrial concentration is low.

as the world's largest renewable rubber producer, China has always adhered to the path of independent research and development and independent innovation in the research and development of process technology and equipment. The desulfurization technology has moved forward from the traditional "oil method", "water oil method" and "dynamic method" to the atmospheric pressure and high temperature continuous desulfurization technology; Special tire crushers, all steel crushers, high-speed ratio, high-speed kneaders and refiners developed for the production of reclaimed rubber have been vigorously promoted and applied, and the industrial automation level, energy consumption level and labor productivity have been greatly improved; In 2002, the promotion of "physicochemical method" environmental protection technology properly solved the problem of treatment of process tail gas, and greatly improved the face of the industry

according to the data, the output of reclaimed rubber in China was 3million tons in 2011, with more than 1500 reclaimed rubber enterprises and no more than 5 enterprises with a scale of more than 50000 tons. The problems faced by the development of the industry: first, most of the enterprises engaged in the comprehensive utilization of waste tires are small in scale, backward in equipment and weak in comprehensive strength; Second, the industry management is relatively weak, the recycling system with standardized operation has not been established, and the enterprises with relatively high technical level are difficult to obtain the waste tire resources required for production; Third, the product technology and quality standards are not perfect, resulting in uneven product quality and affecting market development; Fourth, there is a general lack of technology research and development means and strength, and the ability of scientific and technological innovation is insufficient

the way for renewable rubber enterprises to become bigger and stronger

the "small, scattered and weak" of the renewable rubber industry has led to the lack of product R & D and innovation capabilities of most enterprises, serious homogenization competition in the industry, and the construction of the core competitiveness of enterprises is impossible, seriously affecting the development of the industry and unable to meet the needs of national economic development and environmental protection. To become bigger and stronger, enterprises should pay attention to the following points

first of all, standardized management and stable quality are the cornerstone of enterprise development. Managing quality and managing efficiency is not an empty slogan, but the reality of enterprise production and management. Through the establishment of scientific and reasonable organizational structure system and performance management evaluation system; Through personnel training and technical improvement; Through the implementation of all-round operation process, standardization and digitalization of procurement, formula and production
