Waste tires, often referred to as "black pollution," have long been a global challenge in terms of recycling. Currently, only about 10% of used tires are refurbished worldwide, with China's rate being around 5%. Most waste tires are physically crushed into fine rubber powder, which is then used in applications like plastic runways, but the majority still end up being burned, stacked, or dumped in landfills, causing severe environmental damage. As the world's largest consumer of rubber, China is facing an escalating rubber resource crisis. In response, a groundbreaking technology known as “HL production of rubber raw material complete sets of equipment using waste tires” has emerged. This innovative system reimagines the traditional processing of used tires, transforming them into materials comparable to natural and synthetic rubber. The resulting plasticized rubber powder offers both efficient resource utilization and environmental protection, paving the way for a third source of rubber for China’s rubber industry. Recently, Shanghai Honglei Fine Powder Complete Equipment Co., Ltd. announced that after a decade of research and development, they successfully created a fully automated, closed-loop process to crush waste tires at room temperature, producing high-quality plastic rubber powder that can replace conventional rubber sources. The world’s first 10,000-ton-class production line based on this technology was launched last year at Jiangyan City Honglei Rubber Co., Ltd. This breakthrough marks a major step forward in China’s tire recycling efforts. According to Cheng Yuan, vice president of the China Tire Renovation and Recycling Association, this innovation is rewriting the history of rubber recycling, positioning the plasticized rubber powder as the third major source of rubber resources. According to reports, the cost of producing different types of rubber powder using this technology ranges from 6,000 to 9,000 yuan per ton, making it competitive with natural and synthetic rubber. Large domestic manufacturers like Taiyuan Rubber Plant have already begun using this material, with one general manager stating that it can completely replace imported raw materials, and in some cases, even outperforms traditional rubber in performance. This leads to significant cost savings—up to 0.6 yuan per kilogram of product. Li Jing, director of the Environmental Protection Department under the National Development and Reform Commission, highlighted that 70% of China’s rubber raw materials are imported, with annual consumption exceeding 5.5 million tons. With international rubber prices currently over 30,000 yuan per ton, companies are struggling with rising costs. At the same time, China produces over 430 million tires annually, generating more than 140 million waste tires, putting increasing pressure on environmental and resource management. To address these challenges, Shanghai-based Bao Guoping founded Honglei Fine Powder Equipment Co., Ltd. in 1998. After eight years of R&D, the company developed the first normal-temperature, low-pressure fine powder technology and secured several patents. However, early versions of the rubber powder had limited applications due to low activity. Over time, Bao and his team refined the process, developing a new method that combines physical treatment with a small amount of chemical additives, transforming vulcanized rubber powder into a plasticized form that can be fully integrated with natural or synthetic rubber. This advancement has led to a full set of clean production technologies, with 10 core innovations and multiple national patents. To further promote tire recycling, Bao proposed the concept of “industrial parks,” offering comprehensive services including planning, design, and equipment manufacturing. Several projects are now underway, including a 20,000-ton park in Suzhou, a 30,000-ton facility in Shanxi, and a 100,000-ton base in Xiangyang. In Taizhou, a new cold compounding center is also under construction. Bao believes that tire recycling will eventually become a new industry. To make it sustainable, he emphasizes three key areas: promoting agricultural and industrial tire applications, entering partnerships with global tire brands, and establishing international standards to enable trading in futures markets. With continued innovation and strategic development, the future of tire recycling looks promising.

Herb Cutting Machine

The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
