The primary methods of disposing of waste tires are stockpiling, landfilling, or simple incineration, causing serious secondary pollution. Currently, through various advanced resource utilization methods, the recycling rate of waste tires is steadily increasing.
Retreading: This is one of the most economical and environmentally friendly methods. By replacing the worn tread, a tire can be “reborn,” extending its lifespan. In developed countries, the retreading rate for truck and bus tires is high, but in China, this market still has huge development potential.
Production of rubber powder and reclaimed rubber: This is currently the most important resource utilization method. After waste tires are crushed and the steel wires are separated, they are further ground into rubber powder of different finenesses. The rubber powder can be directly used for paving sports tracks and modifying asphalt, or it can be further processed into reclaimed rubber for manufacturing low-grade rubber products (such as floor tiles, speed bumps, shoe soles, etc.).
