Opportunities and challenges facing the development of China's waste rubber crushing equipment comprehensive utilization industry

2019-06-20

At present, China's waste rubber crushing equipment comprehensive utilization industry has made great progress, especially in the production and application of recycled rubber, China is at the forefront of the world. China's reclaimed rubber production accounts for 73% of the world's total. China's reclaimed rubber production enterprises are located in all provinces, municipalities and autonomous regions in China except Macao and Hong Kong. But at the moment, the waste rubber comprehensive utilization industry, like other industries, faces the overall upgrading pressure of the industry.

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

In 2017, the relevant state ministries and commissions successively issued a series of regulations to promote the development of industry norms, which pointed out the direction for the next development of the industry. In 2018, the task of environmental protection and resource duality undertaken by China's waste rubber comprehensive utilization industry is even more arduous, and the development of industry and enterprises will accelerate the development of standardization and green development.

Recycled rubber is the main method of waste rubber utilization. At present, the main methods of waste rubber utilization in China include tire retreading, recycled rubber, rubber powder and thermal cracking. Among them, recycled rubber has become the third largest rubber resource indispensable to China's rubber industry after natural rubber and synthetic rubber. The direct application of rubber powder is an internationally recognized waste tire environmentally friendly and resource-based harmless processing and utilization method. . Recycled rubber has been used as a recycling economy resource polymer material for 160 years. According to rubber hydrocarbons, every ton of recycled rubber can replace natural rubber or synthetic rubber by 45%, which has a special resource status.

Recycled rubber production is the main force of waste rubber utilization in China, and recycled rubber itself has a good cost performance. More than 70% of the world's reclaimed rubber production is produced in China. China's reclaimed rubber production enterprises are located in all provinces, municipalities and autonomous regions in China except Macao and Hong Kong. The source of waste rubber is mainly waste rubber products, that is, scrap tires, tires, hoses, tapes, rubber shoes, industrial sundries, and corners and waste products produced by rubber enterprises. Tire products consume about 65% of rubber consumption, 35% of other rubber, and 70% of total waste rubber comes from scrapped tires.

According to incomplete statistics, in 2017, China's recycled rubber production reached 4.8 million tons, up 5% year-on-year; rubber powder production reached 700,000 tons, up 8% year-on-year; the main material for producing recycled rubber is rubber powder, 4.6 million tons of recycled rubber needed 4.05 million tons of rubber powder, together with the direct application of rubber powder 700,000 tons, rubber powder production reached 4.75 million tons, China is not only the world's largest producer of recycled rubber, but also the world's largest rubber powder producer.

Second, the opportunities and challenges facing the development of the industry

Since 2017, with the increasingly strict environmental protection requirements, China's waste rubber comprehensive utilization industry needs to achieve green transformation and upgrading as soon as possible to meet the environmental requirements of clean production. Taking into account the impact of environmental factors on the development of the industry, the current development opportunities and challenges facing the waste rubber comprehensive utilization industry can be summarized into the following three points: First, achieving green transformation and upgrading is the industry's biggest opportunity and challenge, and second, strengthening and expanding regeneration. Product application is related to the future of the industry. Third, the gap between waste rubber production and processing volume is a long-term market opportunity.

First, achieving green transformation and upgrading is the biggest opportunity and challenge in the industry. The waste rubber comprehensive utilization industry has made important contributions to solving the shortage of rubber resources and dealing with black pollution. However, the current road to comprehensive utilization of waste rubber really needs a thorough transformation and upgrading. The requirements for the path of transformation and upgrading are green production and green applications. Rubber is recycled, but the recycling process must be clean and green. Green production is a basic requirement. Ecological civilization has been written into the Constitution, giving the industry the clearest requirements for development. Cleaner production will become the basic norm, and the green cycle of waste rubber will be realized in the process of cleaner production. This is also the reality that the industry is generally faced with and must be achieved with the development of the times.

The transformation and upgrading has given new opportunities for development within the industry. It has become an industry consensus to change existing production processes and equipment to achieve clean and automated production. Enterprises are faced with the urgent need for technology and equipment upgrades. Enterprises in the industry are also actively taking action to step up research and development and trial use of new production processes and equipment to achieve cleaner production. In the production of reclaimed rubber, Jiangsu Zhonghong, Anhui World Village, Tiantai Kunrong, Qingdao Zhongjiao, Qingdao Gaoji, Nanjing Lujinren, etc. are all developing new atmospheric continuous desulfurization equipment for production, and do everything possible to reduce desulfurization. The flue gas emissions of the links have also achieved gratifying results, and their equipment has been put into the market and marketed for production applications.

However, at present, atmospheric continuous desulfurization equipment has not been widely applied, and the industry generally uses dynamic desulfurization tanks for production. On the one hand, because the industry still has a certain wait-and-see attitude for the new equipment market, waiting to see the price and utility, on the other hand, there are still specific requirements for environmental protection, and I don’t know if it can achieve the final result. After that, the standardization of environmental protection is also crucial to the development of the industry.

In the production of rubber powder, biaxial crushing, room temperature pulverization has been more and more recognized by the market, and some large-scale complete sets of automation equipment have been put into use one after another, which has greatly changed the overall image of the industry's dirty and messy, using the cryogenic method and the water cutting method. The production technology of rubber powder is also constantly being tested and improved.

With the advancement of technology and the attention paid by the state and society to this industry, the comprehensive utilization of waste rubber can be very clean, environmentally friendly, green and safe. Enterprises in the comprehensive utilization of waste rubber can also Like other companies in the industry, it is standardized, clean, and standardized. In a word, enterprises in the comprehensive utilization of waste rubber industry, whether it is rubber powder enterprises or reclaimed rubber enterprises, can be built into environmentally friendly and clean enterprises that can withstand various inspections and no less than the requirements of other industries.

With the gradual overweight of the country in environmental protection, under the tremendous pressure of environmental protection, the waste rubber comprehensive utilization industry has accelerated the transformation and upgrading. A large number of small and scattered enterprises have completely transformed under the pressure of environmental protection, or they have withdrawn from the market under the pressure of environmental protection. . The waste rubber comprehensive utilization industry will accelerate to the norm, and the transformation and upgrading marked by industry standardization and greenization will accelerate the realization. As an enterprise within the industry, we must actively adjust the development direction, actively respond to the new requirements of the new era of the country, and strive to achieve clean production and complete the green transformation and upgrading of the industry. Abandoning the idea of low-level construction and making quick money, we should treat the comprehensive utilization of waste rubber as a long-term development of the sunrise industry to plan the development of the enterprise; from the business philosophy, under the premise of safe and environmentally friendly production, Improve product quality and increase product added value as the main focus of the operation.

The second is to strengthen and expand the application of recycled products, which is related to the future of the industry. Promoting the application of recycled products is a key part of promoting the development of the industry. At present, the application level of rubber powder and reclaimed rubber is relatively low, and the overall acceptance and recognition of society is not high. This is a major problem that restricts the development of the industry. The healthy and sustainable development of waste rubber and used tires, in addition to the protection of advanced equipment and advanced technology, the popularization and application of recycled products is decisive. Without the widespread application of recycled products, there will be no real green cycle, and there will be no healthy and sustainable development of the entire industry. It will not fundamentally solve the black pollution problem of used tires, and the widespread application of recycled products to the entire industry. The development is of great significance.

The application of recycled products has not been recognized by the concept and is actually popularized. The application of rubber powder and recycled rubber recycled products is still at a low level. The rubber powder industry is an energy-saving and environmental protection industry for resource recycling, and belongs to the field of circular economy. The rubber powder itself is a green product. The rubber powder production is an internationally recognized waste tire (rubber) resource-recycling and harmless processing and utilization method. At the same time, it is an energy-saving industry that is more energy-efficient than the production of recycled rubber. Powder can be applied. However, most of the rubber powder factories in China are small enterprises, and large-scale enterprises should be developed in order to ensure the production and quality of rubber powder and provide users with quality products. Vigorously carry out basic research and applied research of rubber powder, especially in the tire industry. At present, rubber powder is mainly used in the production of recycled rubber and waterproof coiled material. Road asphalt modification is also of experimental nature and has not been widely spread. The application of rubber powder in other fields, such as directly using rubber powder to make products, is still relatively small.

Recycled rubber has been used as a recycling economy resource polymer material for 160 years. According to rubber hydrocarbons, every ton of recycled rubber can replace natural rubber or synthetic rubber by 45%, which has a special resource status. Under the premise of ensuring that rubber products meet the quality indicators, the reclaimed rubber with reasonable use of renewable resources can reduce the consumption of new raw rubber and the amount of carbon black, rubber additives and fillers. Practice three tons of recycled rubber to replace the basic functions of one ton of raw rubber application. Recycled rubber is mainly used in products such as tires, hose tapes, rubber shoes, products, tires, etc., but mainly used as a filler.

Recycled rubber can have more market space. One is the standard lead. With the improvement of environmental protection requirements, the demand for environmentally-friendly recycled rubber in the downstream industry will become larger and larger, and the production of environmentally-friendly recycled rubber will be the basic requirement of the market. China Rubber Industry Association recently developed "E-type recycled rubber" will become the specific standard for environmentally-friendly reclaimed rubber, play a role in eliminating coal tar and promoting the application of reclaimed rubber; second, the technical level of reclaimed rubber application, in the rubber compound and In the development of rubber products, there will be new breakthroughs, and there are already some excellent companies in the industry to try first.

Third, the gap between the amount of waste rubber produced and the amount of processing is a long-term market opportunity. First, the use of waste rubber treatment does not achieve full coverage as a whole. Although China's waste rubber comprehensive utilization industry has a large overall scale, it has not effectively treated all waste rubber, and nearly half of the waste rubber has not been recycled. In terms of the number of tires, the total amount of used tires in the country reached 370 million in 2017, and the weight reached 13.5 million tons. In 2017, recycled rubber and rubber powder recovered and utilized waste tires to reach 6.78 million tons, including prototype utilization and thermal cracking applications of about 8 million tons, but there is still a large distance from the total solution of 13.5 million tons of waste tires. The gap between the demand for recycling of used tires and the actual processing capacity is still relatively large. It is also necessary for the state and society to further increase their attention and input to solve the problem of green recycling of more and more used tires.

According to incomplete statistics, in 2017, China's recycled rubber production reached 4.8 million tons, up 5% year-on-year; rubber powder production reached 700,000 tons, up 8% year-on-year; the main material for producing recycled rubber is rubber powder, 4.6 million tons of recycled rubber needed 4.05 million tons of rubber powder, together with the direct application of rubber powder 700,000 tons, rubber powder production reached 4.75 million tons, China is not only the world's largest producer of recycled rubber, but also the world's largest rubber powder producer. However, China's production of recycled rubber rubber powder is the main raw material mainly for all steel tire waste tires, a large number of small tires and miscellaneous rubber have not been treated. In 2018, the actual production of recycled rubber will be significantly lower than that of 2017, mainly due to the decline in production caused by the closure of some enterprises in environmental protection, with Shanxi and Hebei as the main force. According to preliminary estimates by the association, this part of the production capacity is expected to be around 500,000 tons.

Second, the amount of waste tires produced will increase. The source of waste rubber is mainly waste rubber products, that is, scrap tires, tires, hoses, tapes, rubber shoes, industrial sundries, and corners and waste products produced by rubber enterprises. Tire products consume about 65% of rubber consumption, 35% of other rubber, and 70% of total waste rubber comes from scrapped tires.

The recycling of used tires is still relatively primitive, the standardized recycling system has not been established, and the tire manufacturer's producer responsibility extension system has not yet been finalized.

The number of car ownership is increasing, and the amount of used tires is increasing year by year. Year-by-year increase of used tires, increasing processing gaps, relatively low-end processing technology, simple application of recycled products, and original dispersed recycling systems all require further transformation of the waste rubber comprehensive utilization industry, in the treatment of waste rubber, The use of used tires plays a greater role. This is both a challenge and an opportunity. The environmental problems brought about by more and more used tires have also attracted the attention of the party and the government as well as the social media. The production and operation of the waste rubber comprehensive utilization industry will continue to be more standardized. In the past two years, the National Development and Reform Commission, the Ministry of Industry and Information Technology and other ministries and commissions have also issued a series of policies to promote and standardize the development of the industry, which will have a profound impact on promoting and standardizing the development of the industry.

Building an ecological civilization and protecting green mountains and green hills also requires a greater role in the comprehensive utilization of waste rubber. Solving the black pollution problem caused by waste tires is the historical mission of China's social development to give the waste rubber comprehensive utilization industry. The development of renewable resources industry is an important part of ecological civilization construction, an important means to achieve green development, and an important way to deal with climate change and ensure ecological security. We believe that under the strong care of the party and the government, with the active participation of people of insight in the society, China's waste rubber comprehensive utilization industry will be able to achieve green transformation, achieve healthy and sustainable development, and lead the world's waste rubber comprehensive utilization industry. Make due contributions to the construction of ecological civilization in our country.
