In December 2010, the “Guiding Opinions on Comprehensive Utilization of Waste Tires†promulgated by the Ministry of Industry and Information Technology pointed out that with the rapid development of the national economy and the gradual improvement of people's living standards, China has become a major consumer of rubber resources. At present, China's annual average rubber consumption accounts for 30% of the world's total rubber consumption. Every year, more than 70% of natural rubber and more than 40% of synthetic rubber required by China's rubber products industry need to be imported. The contradiction between supply and demand is very conspicuous. The impact of the development of the national economy is increasingly apparent.
The "Opinions" also pointed out that tires are the most important rubber products in China. In 2009, China's production of tire-consuming rubber accounted for about 70% of the total consumption of rubber resources in the country, producing 233 million waste tires annually, weighing about 8.6 million tons, equivalent to more than 3 million tons of rubber resources, if all can be recycled Use, equivalent to 5 years of natural rubber production in China.
Recycled rubber refers to the physical and chemical processes of waste rubber after pulverization, heating, mechanical treatment, etc., so that its elastic state becomes a plastic and viscous rubber that can be re-vulcanized. It is easy to produce "three wastes" in the production process.
At 11 o'clock on the morning of June 27th, the test base of Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd., the machine conveyor belt was pouring down the recycled rubber pellets just released, and the chairman of the company, Wang Shijun, took the hand and smashed it to the national industry and Huang Jianzhong, deputy inspector of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Information Technology, said: "You see, there is no smog in the workshop, and the smell of the rubber is very small."
In May 2014, the company was selected by the Ministry of Industry and Information Technology as the list of enterprises that meet the industry access requirements (the first batch); on the afternoon of June 27th, an energy-saving and environmentally-friendly waste rubber series cooling dynamic desulfurization waste The new technology was approved by the company through the scientific and technological achievements organized by the China Federation of Logistics and Purchasing.
At this time, Wang Shijun was in a good mood. He told reporters: "Environmental protection is the biggest problem in our industry. If we can't solve this problem, this industry can only die."
Environmental protection to promote the development of renewable rubber industry
Scrap steel, waste plastics, waste paper, used household appliances, used cars, used tires... These garbage, which is labeled as “wasteâ€, is a misplaced resource and is subject to secondary development. Urban minerals.
On June 27th, the reporter went to the Qiangwei Group with the China Tire Renovation and Recycling Association. Chairman Zhu Jun told reporters that the use of waste tires to produce recycled rubber is the main way for China to deal with waste tires. In October 2010, the “Tire Industry Policy†issued by the Ministry of Industry and Information Technology proposed that recycled rubber is one of “three rubbers†(natural rubber, synthetic rubber and recycled rubber), and for the first time, the raw materials of recycled rubber in the tire industry are clearly defined. status.
According to reports, in the 1970s, due to continuous improvement of environmental requirements, the quality of recycled rubber products and production pollution were difficult to completely solve. The production of recycled rubber in foreign developed countries shrank. The rise of China's recycled rubber industry has been forced by the economic and social situation. At present, China has become the most developed country in the world's recycled rubber industry in terms of production scale, product variety, production technology, product quality and production equipment. In 2012, China's recycled rubber production reached 3.5 million tons, accounting for more than 80% of the world's total output. It has ranked first in the world for more than 30 consecutive years.
With the rise of China's reclaimed rubber industry, the significant economic and social benefits of waste rubber, especially waste tire recycling and resource recycling, and the obvious effects of employment have made the international community re-recognize recycled rubber. Some countries in the US and Europe have also begun. Explore and try to break through the environmental bottleneck of the recycled rubber industry.
From the rubber industry, the "new life" road of waste rubber has been very difficult. The recycled rubber industry is an industry that has been repeatedly written in the environmental blacklist because it does not solve environmental problems well.
"You have never seen the old recycled rubber production workshop, the window is black, because the rubber powder particles are flying up. The face is also black. There is also the smell of chemical desulfurization." Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd. Wang Zheng, general manager of the company, described the pollution status of the old-fashioned recycled rubber production to reporters.
In 2013, the environmental pollution incident in the waste tire processing workshop in Yutian County, Hebei Province was much more alarming than that described by Wang Zheng. The media found that there are a large number of waste tire recycling workshops in Yutian County, Hebei Province. The air pollution and odor of the water in these workshops pose a great threat to the health of the local people. In June, Yutian County urgently shut down and shut down 310 waste tire recycling enterprises.
The status quo of the waste tire treatment industry is evident.
Zhu Jun pointed out that due to the low barriers to entry in the industry, the supervision of the management department was not timely, resulting in a large number of small workshops like Yutian County. Those small reclaimed rubber enterprises and workshops at the expense of the environment, extensive manufacturing, low-cost competition, to a certain extent disrupted the market order.
As a company, Wang Zheng said to reporters: "The thermometer is very useful, but the mercury column inside is poisonous. It is necessary to wrap the mercury in the glass to make it harm. The Yutian incident causes vibration in the whole industry. The environmental protection law is suffering from this industry. How to achieve clean and harmless production of recycled rubber is the lifeblood of this industry!"
The environmental situation is extremely pressing. In recent years, the industry has added more concerns about overcapacity.
Li Rulin, vice president of the China Rubber Renovation and Recycling Association Rehabilitation Glue Club, disclosed that at present, there are more than 1,000 recycled rubber enterprises in China with a production capacity of more than 6 million tons. In 2013, China's reclaimed rubber production was about 3.8 million tons, and the capacity utilization rate was about 63%. The internationally measured relatively normal market competition, the more reasonable capacity utilization rate is 80%-85%.
"At present, China's reclaimed rubber industry has experienced serious overcapacity, resulting in a large number of idle equipment. Many enterprises only open two shifts of production, and cause vicious competition of 'grab the cake'. Everyone presses each other and the foreign debts are serious. The smaller," Li Rulin said.
Zhu Jun said that most of these excess capacity is actually the backward production capacity at the expense of the environment. In recent years, the state has introduced a number of policies in the field of waste tire treatment. For example, in 2013, the Ministry of Industry and Information Technology introduced the conditions for access to the waste tire industry. If the company's annual capacity for handling waste tires does not meet the requirements for entry conditions. If the environmental protection does not meet the requirements for access conditions, it is bound to be eliminated.
"The industry is facing a new environmental reshuffle, eliminating small, chaotic, dirty, poor, green and large-scale development." Zhu Jun said.
Innovation to save the industry's magic weapon
On June 28th, the annual meeting of the China Refining and Recycling Association Rehabilitation Glue Club was held in Suqian Qiangwei Group. An important part of the annual meeting is the technical exchange within the industry. The core issue of communication is how to use both environmental protection and resource utilization.
According to Li Rulin, the enterprise technology R&D center in the industry accounts for 7.8% of all enterprises. More than 90% of the enterprises are tracking and imitating others' technology. The R&D investment only accounts for 0.71% of the sales revenue.
Faced with a common environmental red line, they need to find a breakthrough in the industry.
Huang Xianghong, general manager of Taizhou Zhonghong Waste Rubber Comprehensive Utilization Co., Ltd. told the reporter that the company has developed environmentally-friendly waste rubber recovery and recycling equipment. It took about three or four years to invest more than 6 million yuan in research and development. Now it has successfully applied for technical patents. And the products have been sold to Portugal, Spain and other countries. "Our factory is not big, and technical reform is forced out by the pressure of survival."
On the second day of the annual meeting, a group of people in the industry visited the test workshop of Qiangwei Group to observe the “new technology of energy-saving and environment-friendly waste rubber series cooling dynamic desulfurization wasteâ€.
The project was commissioned by the industry and jointly developed by Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd., Huainan Petrochemical Machinery Equipment Co., Ltd., Beijing University of Chemical Technology and China Tire Resources Recycling R&D Center. After two years of scientific research, it solved the regeneration. Environmental pollution, energy conservation and improvement of product quality in the rubber industry.
This is the crystallization of the joint efforts of the Quartet. It includes the technology of strong dimension, the equipment of Huainan Chemical Machinery, the research of Beijing University of Chemical Technology and the China Tire Resources Recycling R&D Center. The China Tire Resources Recycling R&D Center is the R&D center led by China Tire Renovation and Recycling Association. The four aspects together constitute the chain of production, learning, research and association.
Cheng Yuan, an old professor at Beijing University of Chemical Technology, has been engaged in rubber machinery research for a lifetime. He told reporters: "The reclaimed rubber industry is mostly small and medium-sized enterprises. The strength of a single enterprise is small. It is a kind of industry organization to coordinate scientific and technological research and cooperate with each other. It is a kind of A better model of production, education and research is worth promoting. China's renewable rubber industry needs to be bigger and stronger, and we must promote the industry-driven shift from factor-driven to innovation-driven.
Huang Jianzhong also suggested that in addition to technological innovation, the recycled rubber industry can also innovate service models in third-party governance. For example, the BOT model (construction-operation-transfer) in the field of infrastructure investment can be used to export the technology services of enterprises to help more industrial enterprises achieve the goal of environmental protection.
