With the rapid development of the automobile industry, waste tires have become a global environmental problem. Data show that in 2022, the global production of used tires reached 1.78 billion, of which China's annual production of more than 350 million. These "black pollution" not only occupy land, breeding mosquitoes, but also pose a risk of spontaneous combustion. In this context,  the Professional pyrolysis plant of Henan Xinxiang LEFILTER  has opened up a new path for waste tire treatment, and its technological breakthrough and environmental benefits are worthy of in-depth discussion.

The traditional waste tire treatment method has obvious disadvantages: landfill occupies land and is difficult to degrade, incineration produces highly toxic substances such as dioxins, and mechanical crushing has a low recovery rate. The high temperature cracking technology developed by Liffert breaks down tires into fuel oil (45%), carbon black (35%), steel wire (15%) and combustible gas (5%) in a closed, oxygen-free environment at 500-600 ° C. The technology to achieve "eat dry press" : each ton of waste tires can produce 420 liters of fuel oil, equivalent to saving 0.6 tons of crude oil; The properties of the extracted carbon black were comparable to those of industrial carbon black after activation treatment. The steel wire can be reused directly in the furnace. After third-party testing, the concentration of particles emitted by the process is only 0.8mg/m³, far lower than the national standard (20mg/m³), and truly realize harmless treatment.

The double breakthrough of economic benefits and environmental protection value Taking Lifeldt's demonstration project of handling 100,000 tons of waste tires annually as an example, its economic benefits and environmental benefits are remarkable. The total investment of the project is 120 million yuan, and the annual processing cost is about 20 million yuan, while the annual output value of fuel oil, carbon black and other products is 180 million yuan, and the investment payback period is only 2 years. In terms of environmental protection, the project can reduce carbon dioxide emissions by 180,000 tons per year, equivalent to planting trees on 12,000 mu. More importantly, the technology breaks the traditional "treatment is loss" dilemma - through the recycling of resources, each ton of tire treatment can obtain a profit of about 500 yuan, providing economic support for the sustainable development of the industry.

China's "14th Five-Year circular economy development Plan" clearly put forward the "construction of waste tire resource utilization demonstration project", Henan Province will be the high temperature cracking technology included in the key promotion catalog. With the release of policy dividends, Liffert has laid out 12 processing bases across the country, with an annual processing capacity of more than 1 million tons. It is worth noting that the technology can also be extended to the field of solid waste such as plastics and rubber, and the continuous cracking equipment developed by the company improves the treatment efficiency by 40%. Experts predict that by 2025, China's high temperature cracking capacity will account for 30% of the total amount of used tires, and the market size will exceed 20 billion yuan.

Challenges and opportunities in technology iteration Despite the significant advantages of high temperature cracking, the industry still faces challenges such as high initial investment in equipment (a single set of equipment costs about 8 million yuan) and inconsistent technical standards. In this regard, Liffert is reducing equipment costs through modular design and working with scientific research institutions to develop industry standards. It is worth noting that the low-temperature catalytic cracking technology it is developing can reduce energy consumption by 25%, and the cracking temperature can be reduced to about 400 ° C, further expanding the application boundary of the technology. With the promotion of the goal of carbon peak and carbon neutrality, the waste tire treatment industry will usher in a golden development period.

LEFILTER's high temperature cracking technology provides an economical and environmentally friendly solution for waste tyre disposal. The realization of "turning waste into treasure" through technological innovation not only solves the problem of environmental governance, but also creates considerable economic value. In the context of the dual-carbon strategy, the promotion of this technology will accelerate the upgrading of China's solid waste treatment industry and provide a "Chinese solution" for the global circular economy. As the head of the company says, "We're not dealing with waste, we're creating resources." This technological revolution is the key to solving the contradiction between environment and development.
