Process Technology

1 Process technology: green cleaning

  • Star's ultra-high pressure water jet crushing technology: uses ultra-high pressure water jets to impact the tire tread, sidewall and other parts to break the original polymer chemical bonds, peel and crush the rubber from the tire surface, and produce a new type of rubber powder.

100% utilization of waste tires, green and environmentally friendly without pollution


2 Process Technology-Solving Industry Pain Points

  • Dependence on imports: Activated rubber powder can partially replace natural rubber and be used in strategic rubber products such as tires and hoses, greatly reducing dependence on natural rubber.

  • Low recycling rate: A continuous production line has been built to achieve large-scale and efficient production, solving the current low recycling rate of waste tires.

  • Low added value: Activated rubber powder is used in high-end markets such as the rubber industry, with high added value, better performance, and a circular economy

  • High pollution: The company independently developed the world's first complete production line, which is efficient and clean, and does not produce any pollution or waste.

  • High energy consumption: The production process of activated rubber powder has low energy consumption and is pollution-free. It has been listed as a strategic new material by the country.
