Beijing Productivity Society: Rationalization of Scrap Tires in Beijing

Beijing's car ownership will enter 5 million vehicles. As the number of car ownership increases, the number of used tires will increase accordingly. A car is counted on 4 tires. Beijing renews tires every four years. The total volume is 20 million, and the average annual replacement is about 5 million. These used tires will cause Beijing to face "black pollution," but it is also a recycling resource. How to reduce the resource consumption of rubber and fully develop and use waste tires as renewable resources has made it imperative to promote the development of the comprehensive utilization of used tires.

In recent years, although China has initially established an industrial chain for the comprehensive utilization of used tire resources, from the renovation of used tires to the use of used tires to produce recycled rubber and rubber powder. In addition, thermal cracking of waste tire rubber has formed a pattern of comprehensive utilization of waste rubber, mainly reclaimed rubber, and suitable development of rubber powder, resulting in the development of retreaded tires. However, there are currently small-scale enterprises, low-efficiency, backward technology and equipment, weak innovation capacity, and imperfect environmental protection measures. At the same time there are still the following aspects:

1. There are no relevant laws and regulations and economic incentives and preferential policies for the recovery and recycling of used tires.

2. There is no standardized recycling system. Currently, the “recycling-transporting-simple processing-distribution” system formed spontaneously by the scavengers in the cities.

3. The industrial structure is irrational. There are no technical requirements and technical standards for waste tire processing and processing enterprises to prevent secondary pollution. At present, the secondary pollution of processing and processing enterprises is serious.

4. The market for recycling, disposal, processing, and recycling of used tires is in anarchy, management is chaotic, there is no industry access mechanism, there is no social environment for waste tire recycling, and fees and compensation mechanisms for public service costs.

In response to the current problems in the development of the industry, the following suggestions are made:

1. Accelerate the development of regulations for the recycling of used tire resources, manage them according to law, and standardize the development of the industry. Beijing Municipality shall establish and improve regulations and rules for the management of waste tire recycling as soon as possible, clarify the responsibilities and obligations of the production and use units, scientifically position the comprehensive utilization of used tires, establish and improve the recycling channels for used tires, and collect the recycling fees. , registration, payment, use and management methods; stipulate industry organization and management, coordination, supervision, planning, preferential policies, research and development of waste rubber utilization technology, secondary pollution control, product and raw material standards, recycling, statistics, bulletin, rewards And penalties, and the qualification certification system for waste tire recycling companies.

2. Given that Beijing lacks a complete waste tire vein industry system and the processing and reuse links in the industrial chain are weak, drawing on the experience of developed countries in setting up a waste tire industrial chain, the industrial chain of waste tires in Beijing needs to break through the limitations of the region and should be fully implemented. Based on the comparative advantages of Beijing, neighboring regions, and even different regions of the country, we will make full use of peripheral resources, establish and improve a socialized industrial development system, establish a group of scientific research and production companies with processing technologies, and establish Beijing as an industrial chain. Big industry chain.

For example, the former Beijing Rubber Factory No. 6 is a professional production system based on reclaimed rubber, which can be transformed on the basis of the production equipment and product structure of the rubber plant of Beijing Rubber Industry Co., Ltd., plus some related rubber plants in Tianjin and Hebei. To adjust the structure of the rubber production industry. Remanufacturing and remanufacturing of old tires - the production of recovered rubber from waste tires - fine rubber powder - low temperature pyrolysis of fuel oil - extraction of high value-added products to form a recycling industry chain. This will not only solve the industrialization of the comprehensive utilization of used tires, but also put forward proposals for the restructuring of the Beijing rubber production industry. To achieve the purpose of harmless recycling of used tires and recycling of waste tires.

3. Improve the incentive policies and mechanisms for the recycling of discarded tire resources. From the perspective of the market composition of the industry, the composition of the employees, and the convergence between the various links of the industry chain, the strength and joint points of government support are established, and the degree of marketization of industrial development is enhanced.

First of all, it is necessary to increase the price competitiveness of formal recycling and processing companies and use the price mechanism to guide the actions of individual scavenging forces. The government must provide proper tax incentives or subsidies for formal enterprises, provide appropriate technical support, and strengthen the management and training of employees. Through various channels, increase the investment in the technological development of the comprehensive utilization of used tire resources. Comprehensive use of discarded tire resources for technological development, high-tech industrialization demonstration projects, into the scope of science and technology three expenses support; used tires included in the national mandatory recycling catalog, the implementation of "old for new" system, established tire recycling in various districts and counties processing and distribution center Responsible for centralized collection, classification, primary processing and reuse of used tires in the region.

Secondly, it is necessary to guide the establishment and operation of the second-hand transaction market for used tires, and strengthen quality supervision, standardize the safety certification system, and form a market approach for the reduction of used tires. At the same time, it is necessary to strengthen the interaction and cooperation between administrative subjects and market players and establish a resource integration mechanism between municipal processing companies and recycling companies. Preferential taxation policies are applied to waste tire processing and utilization enterprises to reduce the burden on enterprises.

4. Policy guidance is required for the most scientific and value-added resource recycling methods for the recycling of discarded tires. For example, although there are many ways to use used tires such as retreading, shredding and making fuel for power generation, chemical cracking and recycling of carbon black and fuel oil, making rubber pellets, etc., there is an increasing trend in the world to use scrap tires to produce rubber powder. . Because rubber powder has an irreplaceable advantage. The latter did not have the pollution caused by the production of reclaimed rubber, and there was no other secondary pollution. The most amazing thing about rubber powder is that it can make the use of used tires 100%, can be recycled, and is truly recycled and sustainable. The development of rubber powder industry is the direction of comprehensive utilization of waste tire resources. China's rubber powder industry has just started, production technology has reached world-class level, and the key is application and promotion. It should organize and coordinate the application of rubber industry, building materials industry, highways, public places and other fields. , And give policy support to rubber powder production and application units, introduce standards as soon as possible, and give preferential taxation.

5. Promote the use of rubber powder in modified asphalt for use in urban roads and highways. U.S. highway paving materials require that more than 25% of rubber powder be added to bitumen to prevent freezing, slippage, and waterproof collapse, as well as to increase the static and dynamic strength of the road surface, and to increase the bearing capacity of the road surface (approximately 4 times). . The technology for producing rubber powder in China is advanced, but the technology of applying powdered powder cannot keep up with the market. The application market has not been opened, and China's application on the highway is still in the experimental stage, and it has not been fully promoted. In the past two years, the Beijing Municipal Bureau of Roads has also conducted research on the use of waste tires to produce rubber powder, and has promoted the use of waste tires that have been processed and used to pave roads during major road repairs. The waste tires are mainly ground into granules by physical means and added to the asphalt mixture for paving. The use of waste tires to produce rubber powder technology has begun to be applied to the overhaul of high-grade pavements such as the Beijing Fourth Ring Road and Jingtong Expressway, which has reduced road construction costs by 10%-20% and reduced road noise by 2-4 dB. This is equivalent to a reduction of traffic flow by about 30%. To this end, Beijing should fully promote the application of rubber powder modified asphalt in urban roads and highways, and it should be included in regulations.

The recycling industry of waste tires has high economic and environmental benefits and is an important part of China's development of circular economy. The recycling potential of used tire resources in Beijing is huge, and the market prospects are good. It needs to be supported by the government and society in various ways to promote the healthy development of the recycling of waste tire resources.
