Innovative Development of Tire Recycling Implementation of "Made in China 2025"

"Through several years of efforts, the layout of China's waste tire recycling industry has become more rational, and the scale of production has continued to expand. The tire recycling industry must implement the "Made in China 2025", promote the development of the resource utilization industry, implement innovation-driven, green development, and improve Tire recycling utilizes industrial competitiveness.

“Hangzhou Zhongce Rubber Circulation Technology Co., Ltd. has carried out trial construction of waste tire recycling system in Zhejiang and other places. Despite many problems in operation, it has actively explored the construction of waste tire recycling system. A key step has been taken."

Zhu Jun, president of the China Tire Recycling Association, said at the 2015 annual meeting of the China Tire Recycling Association held in Qingdao that after several years of efforts, the waste tire recycling system has been initially completed, the industrial layout has become more rational, and the scale of production has continued to expand. According to incomplete statistics, there are more than 800 tire retreading enterprises registered in China with an annual production capacity of about 20 million; more than 1,500 waste tire recycling companies, annual processing capacity of recycled rubber is about 5 million tons, rubber powder Processing capacity is about 1 million tons and thermal cracking is 200,000 tons.

China Tire Recycling Association's first "Green Development, Win-Win Future" industry development summit forum and the 12th China International Tire Resource Recycling Exhibition were held in the same period. Li Hongliang, a researcher of the Department of Resources Comprehensive Utilization of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said at the meeting that the tire recycling industry must implement “Made in China 2025” to promote the development of the comprehensive utilization of resources, practice innovation, promote green development, and improve tire recycling. Industrial competitiveness.

The level of technical equipment has been improved

After years of exploration and development, China's tire recycling field has formed four business segments: tire retreading, recycled rubber, rubber powder, and thermal cracking. A complete industrial chain for waste tire processing and utilization has begun to take shape. Old tire retreading is the internationally recognized preferred method for tire reduction, reuse and recycling. Recycled rubber has become the third largest rubber resource indispensable to China's rubber industry following natural rubber and synthetic rubber; rubber powder is directly applied. It is internationally recognized as an environmentally friendly, resource-based, harmless processing and utilization method for waste tires; thermal cracking is the final step in the recycling of waste tires, and is an important means to “eat dry pressed nets” for waste tires.

In recent years, China's tire retreading industry has continuously improved its production technology, continuously improved its production process, and continuously innovated its technical equipment. Most tire retreading companies have adopted the international advanced pre-vulcanized tire retreading technology, and the quality of products and technology have been in line with international standards. The key equipment required for the retreading of tires in China has mainly depended on imports to achieve localization, and most products have reached or reached the international advanced level.

In order to achieve the goal of energy saving and environmental protection, the waste crusher automated crushing production line, vulcanized rubber powder atmospheric pressure linkage environmental protection reclaimed rubber equipment and technology, reclaimed rubber linkage kneading, and automatic weighing of the complete chip complete set have been put into use, which can reduce the operator by 50%. , Save 20%, increase production by 25%. The reclaimed rubber industry transformed the traditional dynamic desulfurization process and adopted an internal cooling-cooling series process to relieve the pressure on the environment. While improving the environmental awareness of enterprises, some companies have begun to transform their technical equipment and provide special environmental protection equipment. As a result, the production energy consumption of recycled rubber has dropped from 980 kW·h in the “11th Five-Year Plan” period to 880 kW in the “12th Five-Year Plan”. h, reducing energy consumption by 11%.

However, according to Zhu Jun, in recent years, due to the influence of domestic financial markets and commodity markets, the development status of the entire industry has not been evenly balanced. According to incomplete statistics, in 2014, the tire retreading volume in China was 9 million, compared with that in 2010. 14 million were reduced by 5 million, 17.15 million less than the 26.15 million predicted by the “Twelfth Five-Year” development plan; the output of reclaimed rubber was 4.1 million tons, 1.1 million tons more than the 3 million tons in 2010, and was 2.6 million tons predicted by the development plan will increase by 1.5 million tons; rubber powder output will be 550,000 tons, an increase of 300,000 tons compared with 250,000 tons in 2010, which is 250,000 tons less than the 800,000 tons forecasted in the “Twelfth Five-Year Plan”; Thermal cracking is 80,000 tons, 30,000 tons more than 50,000 tons in 2010, and 20,000 tons less than the 100,000 tons forecasted in the “Twelfth Five-Year Plan”.

Several major problems hinder the development of the industry

Although China's tire recycling industry has achieved considerable development during the "12th Five-Year Plan" period, Zhu Jun still has some problems that cannot be ignored. Only by fully understanding and carefully analyzing these issues can we gradually solve them.

First, extensive production and management methods. Although the recycling of waste tires has become a resource-saving sunrise industry, due to historical and practical constraints, most companies have a lack of operating funds, a small scale of production, a low level of technology, and management methods and management methods are lagging behind. Development. Some small-scale enterprises in the industry rely on backward production technologies and processes to adopt extensive and low-cost, low-value-added, high-energy-consumption, high-emission exhaustive production and management methods, which have impacted the market order and caused disasters to resources and the environment. Sex destruction.

The second is weak market supervision. In recent years, through the guidance of the country’s macroeconomic policies and the gradual strengthening of industry management, the awareness of self-discipline and self-development has increased in some large and medium-sized production enterprises. The quality of products has approached or has been achieved on the basis of constantly updated technologies, equipment and processes. The international advanced level can better meet the user's requirements and become the backbone of the industry. However, due to historical and objective reasons and the absence of some policy measures, there are still a large number of small-scale enterprises that are outside the supervision of the market and are in a situation of free development. Their technical equipment is backward, the production level is low, product quality is not guaranteed, and even fake and shoddy products are produced, which seriously damages the overall image of the industry.

Third, the waste tire recycling system has not yet been established. Although in the past two years under the organization of the association, the Ministry of Commerce has successively promulgated the "Standard for the Selection of Tires for Commercial Old Tires", the "Construction Regulations for Waste Tire Recycling System", and the "Rules for Waste Tire Recycling and Management" for the construction of waste tire recycling systems. Industry standards and pilot work have been initiated in some regions, but at present, no nationwide normative waste tire recycling system has been established. More than 95% of waste tires are traded by the private sector, causing a considerable amount of scrap tires to flow into non-standardized industries. The processing and processing manufacturers are also one of the main reasons that cause the waste of rubber resources in our country and cause secondary pollution to the environment; and the disorderly competition of recycling operators not only makes the limited waste tire resources unregulated and reasonable, Efficient recycling, but also makes a lot of normative companies face the dilemma of resource shortages, but the layers of reselling and transshipment waste of transportation resources.

Fourth, business operations are difficult. In the past two years, due to the influence of international and domestic economic conditions, some production enterprises have encountered unprecedented operational difficulties and their operating conditions are not optimistic. The lack of raw materials for production, shortage of funds, and weak technical support, combined with the intensification of free competition in the industry, have become the embarrassment for many companies to achieve sustainable development.

Fifth, there is a shortage of retreaded tires. Tire refurbishment is the internationally recognized preferred method for tire reduction, reuse, and recycling. However, some tire retreading companies with large scale and standard operation in China are in serious shortage of retreadable tires and have long been in a position of idle production capacity. . On the one hand, more than 800 manufacturing enterprises registered have an annual production capacity of about 20 million, but in 2014, the output was only 9 million, and the idle rate of production capacity exceeded 50%. On the other hand, the proportion of used tires was seriously out of balance, and waste tires were seriously unbalanced. The ratio of production to old tires is approximately 95:5. Old tires that can be used for retreading account for only 5% of the total used tires, which is a far cry from the average level of 45% in developed countries. The reasons are as follows. First, the state has not incorporated the retreadability requirements of tires into the mandatory technical standards for new tire manufacturing. In addition, some “no new three-packs tires” flood the market with poor product quality and no renewal. Second, artificially limiting the scope of use of retreadable tires. For example, in September 2012, GB 9.258-2012 “Safety Requirements for the Operation of Motor Vehicles”, Section 9.1.2 clearly states: “Road passenger cars, tourist buses and school buses. "Steering wheels for all wheels and other motor vehicles must not be fitted with retreaded tyres". It is a "one-vote veto" for passenger cars using retreaded tyres. Third, people have a weak sense of scientific use of tyres, overload, overrun and excessive wear and tear. Seriously, most of the new tires “went to waste” and lost the opportunity for refurbishment. Fourth, since there was no established old tire processing and utilization channel, a certain amount of used tires flowed to non-standard enterprises. The products produced cannot meet the product quality standards and national requirements for energy conservation and environmental protection; Fifth, the current state imposes restrictions on the import and prohibition of used tires. The policy of importing waste tires cannot fully utilize both domestic and international markets and resources.

Sixth, it is an environmental issue for the recycling of waste tires. At present, the main methods for the recycling of waste tires in China are the production of recycled rubber, the production of rubber powder and the thermal cracking. Together with the old tire retreading industry, they formed an industrial system with recycling of used tires with Chinese characteristics. Although many advantages of the recycling of waste tires have been gradually recognized by the society, there are still problems that should be solved: First, the secondary pollution of recycled rubber and thermal cracking to the environment; Second, the high energy consumption of recycled rubber production equipment. problem. Guided by the “Guidelines for the Comprehensive Utilization of Waste Tires” and the “Admission Requirements for Waste Tire Comprehensive Utilization Industry” issued by the Ministry of Industry and Information Technology, some reclaimed rubber and thermal cracking production companies have conducted technologies in environmental protection and energy conservation. Improvements and innovations in technology have taken a step toward safety, environmental protection, and continuous production, but some common problems affecting product quality have yet to be resolved. Therefore, the use of environmentally friendly, energy-saving, continuous, and highly efficient reclaimed rubber production equipment and environmentally friendly additives has become the goal of the industry to convert to low-carbon green.

Seventh, the strength of science and technology is weak. As a national strategic emerging industry waste tire recycling industry, the average level of employees in the industry is low, R&D institutions are not perfect, the number of experts is too small, and the age is too large. Many theoretical problems and key technical problems that restrict the development of the industry are not To a very good solution, it has restricted the rapid development of the industry to varying degrees.

Seize the opportunity to stabilize the cause

Although the current tire recycling industry is facing a very arduous task and a greater pressure, but Zhu Jun believes that from a macroeconomic point of view, during the "Thirteenth Five-Year" period, tire recycling industry will usher in a more favorable and rapid An important period of opportunity for development.

During the “Thirteenth Five-Year Plan” period, China’s auto industry will further develop, and the shortage of rubber resources will further intensify, both in terms of the supply of domestic energy resources and the bearing capacity of the ecological environment, as well as the trend of global economic development and greenhouse gas emissions. In terms of space, China cannot continue to rely on extensive growth methods to advance the process of modernization. Therefore, continuing energy conservation and environmental protection, accelerating the development of green industries, and nurturing and developing strategic emerging industries will surely become an important way to promote economic growth and transformation. This will undoubtedly promote the further development of the tire recycling industry. The entire industry must seize opportunities and take positive actions.

Actively improve the business environment and standardize market operations. Actively strive for the level of attention of various levels of government departments to the industry, and strive to win the country's support for the development of circular economy, especially the preferential fiscal and taxation policies, to create a suitable external environment for the development of the industry. It is strongly recommended that the state issue relevant policies and regulations to incorporate the management of tire recycling into the legal system. Continue to implement the industry access system for comprehensive utilization of used tires. Taking the access conditions of the industry as the starting point, rationalizing the order of market operations, purifying the business environment of the enterprise, standardizing the production and operation of the enterprise, and promoting the optimization and upgrading of the enterprise, so as to guide the healthy and orderly development of the industry. Efforts are made to improve the investment environment, attract domestic and foreign investment, and build a batch of industrialized and large-scale large and medium-sized enterprises with the help of external funds and resources. Make full use of "two markets and two resources." Actively recommend that the competent government departments carry out trials for the import of waste tires and expand the pilot range of imported old tires so as to ease the serious shortage of rubber resources in China. It is proposed to revise the clause in the “Guidelines for the Safety of Motor Vehicles” in GB7258-2012 which is not conducive to the development of the tire retreading industry, and to expand the scope of use of retreaded tires. Establish a sound waste tire recycling system, start from the source of waste tires, based on the pilot work at the current stage, sum up experiences, advance in an all-round way, and explore a recycling road for waste tires suitable for China's national conditions.

Improve the mechanism to regulate the operation and promote the transformation and upgrading of enterprises. Research and establish a system of producer responsibility extension, clarify the responsibilities and obligations of tire manufacturing enterprises, and establish a management system for the comprehensive utilization of used tires in accordance with the law, so as to ensure the comprehensive, coordinated and sustainable development of comprehensive utilization of used tires. Seize the opportunity of industry adjustment and economic revitalization, guide enterprises to deepen reforms, establish and improve incentive and restraint mechanisms and modern enterprise systems, strengthen enterprise quality management, financial management, energy conservation management and safety production supervision and management, strengthen the construction of workforce, and comprehensively upgrade enterprises. Management level, to promote enterprises to achieve leapfrog development. We will vigorously develop a recycling economy and work hard to develop the industry chain. Through deep processing to diversify the direction of development to achieve waste tire resources from one-way development to comprehensive development, from extensive development to intensive development, from primary processing to fine processing, and gradually form a complete industrial system of recycling of waste tire resources.

Strengthen innovation research and strengthen technical service support. Actively promote technological transformation and technological innovation. Continue to improve the standard system for comprehensive utilization of used tires. Study and formulate national standards for "3C" certification for tire retreading, and strive to require "3C" certification for retreaded tires during the "Thirteenth Five-Year Plan" period. China National Tire and Recycling Association will take the lead in the preparation and processing of used tires. Technical standards and waste tire processing energy consumption and environmental standards, increase the standardization of rubber powder application of downstream products. Encourage and support qualified companies to establish research institutes and R&D centers for engineering and technology, and set up a production-study-research institute to concentrate on the construction of a number of demonstration projects, processing bases or industrial parks with appropriate scale, advanced management, high technology content, and energy-saving environmental protection requirements. With this as the center, we will promote the construction of the waste-tire recycling-processing-utilization industrial chain around and even around the country.
