The way to make money

Core reading

As a solid waste, the waste tire is known as \”black pollution\” in the industry. If nothing is properly disposed, not only resource waste, but also brings environmental impact. A few days ago, the Ministry of Industry and Information Technology issued a document from many aspects to the comprehensive utilization of waste tires.

What is the current situation of comprehensive utilization of waste tires in my country? How can I better promote the green healthy development of the industry?

According to statistics, in 2019, my country’s waste tires were about 330 million, and the weight exceeded 10 million tons, and the annual scrapped tires were still continued to grow at 6% to 8%.

In order to promote the comprehensive utilization of waste tires, the industries continue to be healthy and healthy, and the Ministry of Industry and Information Technology (2020) \”, from the technical equipment and process, ecological environment protection, product quality control, product quality control Aspects of safety management have proposed specifications.

Waste tires \”eat net\”, the recycling rate is increased year by year

Not long ago, the Kaiyuan Runfeng waste wheel fetal cracking base in Zouping City, Shandong Province.

A car is full of waste tires to enter the factory, and the removed tires are removed by the forklift to the above-free zone. After crushing and cleaning, after pretreatment, \”feed\” into automatic cracking equipment , The lytic oil generated by the reaction, carbon black into the sales and re-processing step, and the gas is converted to the furnace as a fuel reuse.

Waste tires \”eat net\”, such a scene source self-continuous and automated production equipment, and the innovation of process flow. \”Automated feed, full-closed production process, continuous output, no manual intervention, in this way, heat cracking, almost 100% of waste tires,\” Shandong Kaiyuan Runfeng Environmental Protection Technology Co., Ltd. Meng Xiangdong said.

\”Hot Cracking\” in Meng Xiangdong, is to crush the waste tire, which is placed in a closed container, and decomposes it under high temperature and high pressure), which is one of the main methods of comprehensive use of waste tires. According to reports, there are currently in the industry’s waste card, which is treated, most of which is treated, producing regenerative rubber and rubber powder. Among them, the regeneration rubber powder is used in the particle size, partially used in the production of regenerated rubber, and the other part is used to produce a modified asphalt or waterproof coil. Semi-steel tires, synthetic rubber waste passenger tires are commonly used in thermal solution.

\”In the past, the waste gas was discharged in the process of exhaust gas waste during the cracking process, which caused serious damage to the environment.\” Zhu Jun, president of China Tire Recycling Association, said that in recent years, with Key technologies continue to fight, environmental management is increased, and the industry’s landscape, small, pollutant, and chaotic industry patterns have gradually changed. The new type of thermal cracking technology has become one of the important directions of comprehensive utilization of waste tires.

from hot crackThe transformation of the solution is fully equipped, and since the 2012 Working Department issued a comprehensive use of waste tires, six batch of 80 cases of entry conditions have been announced. \”These access companies are concentrated, and the technical equipment level is higher, representing the advanced level of the industry, and it has been leading role in the green circular utilization of waste tires.\” Zhu Jun said.

Waste tires are illegally discarded or stored, and it is easy to become a nest area of \u200b\u200bpests and mosquitoes, which may also spread disease.

In addition, the waste tires are easy to get fire, release a large amount of smoke, which contains toxic gases such as carbon monoxide, sulfur dioxide and a small amount of polycyclic aromatic hydrocarbons, and threats to public health and environmental safety.

Accelerating the comprehensive utilization of waste tires not only helps to reduce pollution, effective governance, or to save resources. my country is a big rubber consumption, and if you can use waste tire resource utilization, it can effectively improve resource utilization efficiency.

Under the leading economic policy, in recent years, my country’s waste tire comprehensive utilization industry has rapidly developed rapidly, and the recycling rate of waste tires has increased year by year. In 2019, approximately 1,500 enterprises, and resource recovery was about 200 million, and the recycling rate was about 60%. Among them, the tire refurbished amount is about 5 million standard fold bars, and the regeneration rubber production is about 3 million tons, and the rubber powder production is about 1 million tons, and the heat cracking treatment is about 1 million tons.

Lack of mandatory refurbishment standards, the relative low tire refurbishment rate

\”From the current reuse form, the regeneration rubber and rubber powder are the main force of the waste tire treatment, accounting for all the year More than 50% of the amount, continuous and automated thermal cracking is relatively low, and the tire refurbishment rate is only 5%. \”Zhu Jun said.

In fact, tire refurbishment is the preferred way of recycling of tire resource. Zhu Jun explained that with 35% of the original tire, 40% of the energy consumption and 50% or less price, the running mileage can reach more than 90% of the new tire.

Superior performance, high cost performance, why is my country’s tire refurbishment? Operating tire refurbished business for many years Beijing Jilong Tire Renovation Co., Ltd. Chairman’s chairman of the chairman: At present, the domestic tire lacks mandatory refurbishment standards, and there is a \”one drum to waste\”, and the tire wear is considered to replace it. New tires, which makes replacing the tire carcass can’t meet the renovation requirements, causing tires to refurbish the production of \”no rice pot\”.

Optimacy, issued related standards and tire producers’ responsibility extension systems, requiring companies to be responsible for the recycling of products.

On the other hand, people have to change the concept of tire refurbishment. \”At present, my country’s renovation tires are almost zero in the field of passenger cars.\” Analysis of industry people, now there are still many passengers still doubtful to the quality of refurbished tires, mostly after tiresChoosing simply patches or replacing new fetures, which also causes such waste tires that cannot be reasonably utilized.

The industry has broad development, and should develop more regenerative resources on the basis of protection of the environment

in Yinan County, Henan Province, through a dozen critical technical problems, Shuangxing Yksda Waste The rubber green cleavage intelligent factory achieves \”zero pollution, zero-residue, zero emissions, all use\” for waste tires. The industry believes that: \”This will help the industrialization of the hot cracking project in the future in the local promotion and replication.\”

As a strategic emerging industry, despite the problem of the problem, in the investigation, interviewed enterprises View the market prospects of the comprehensive utilization of waste tires. In fact, accompanied by the continuous norms of national environmental policies and industry order, the waste tires are turned into \”black gold\”.

Meng Xiangdong calculated a bill for the reporter: with the annual treatment of waste tires with 60,000 tons of waste tires, can receive 24,000 tons of lysate oil, 25,000 tons of carbon black, 0.72 million tons of steel wire and a small amount Gas, the annual sales of these products are expected to reach around 80 million yuan.

This calculated, if the national annual waste tires are standardized, or the annual output value of over 10 billion yuan can be formed.

my country’s car ownership is still growing, providing adequate market foundations for waste tire markets. In addition to the demand for strong, there are policy support. Previously, the National Development and Reform Commission issued a guide catalog, clearly identifying the comprehensive utilization of waste tires as a strategic emerging industry, making it a Chaoyang Industry in Lee-Rigi.

The foreground is good, the opportunity has come. How to achieve a comprehensive utilization industry of waste tires?

\”To get more regenerative resources as much as possible in the premise of protecting the ecological environment.\” In the view of Zhu Jun, the overall tone of the future industry development is based on ecological environment, to achieve cycle development. To drive, energy saving and emission reduction is the path to obtain renewable resources as the target, actively explore the development of my country’s national conditions, and the development of the world tire circulation can be drawn, and contribute to the human ecological environment.

Specifically, the industry suggests that the next step in the tire refurbished industry may wish to enter the logistics transportation market, aim at the target customers, jointly relevant industry organizations to build a resource platform, and grasp the transportation enterprise, obtain waste tire resources; Specification, provide quality product services. Recycled rubber and rubber powder industry can continue to improve process technology, research and development, and adopt new technologies, new processes and new equipment for energy conservation and environmental protection.

For thermal cracking, resolutely ban \”earthwork refining\” production, encourage guidance enterprises to move towards continuous, automation and intelligent production, achieving cleaning, low energy, and efficiency.
