Most tire recycling processes involve landfilling or incineration. This leads to secondary pollution of soil, vegetation, and groundwater, making the search for resourceful tire recycling methods particularly crucial.

Waste tire disposal methods currently include the following:

1. Tire Retreading: Tire retreading technology involves repairing and reprocessing worn-out or damaged tires, restoring their usability. In our country, the retreading rate of used tires is less than 5%, which is a mere drop in the bucket compared to the total inventory of used tires.

2. The recycling of waste tires into oil involves adding catalysts and refining through heating and pressure. This technology, if implemented with simple and inexpensive equipment, can easily lead to secondary pollution.

3. Regenerated rubber can replace some natural rubber in rubber products, but the dynamic desulfurization process under high temperature and high pressure during the production of regenerated rubber generates secondary waste gas pollution, posing risks during production and leading the industry into a downward trend. Tire rubber powder regeneration, a technology for tire rubber powder regeneration, involves first using equipment to crush waste tire rubber powder into 20-30 mesh rubber powder, and then subjecting the powder to desulfurization treatment to reform it into soft, malleable, and pliable regenerated rubber, which can be reprocessed into various rubber products. If the desulfurization process technology is not up to par, it can also lead to pollution.

4. Tire rubber powder is used for waterproofing and leak repair. Waterproof membranes are primarily used for house leak prevention, and it's common for most houses to undergo waterproofing and leak-proofing treatments. This industry is widespread across the country, with a substantial demand for waterproof membranes. Rubber powder is a key ingredient, as waterproof membranes are a type of modified asphalt.

5. The "pyrolysis" reuse of scrap tires is a crucial method and direction for the recycling of waste tires. After 2-3 cycles of reuse, rubber products can no longer be used for producing rubber goods.
