What are the disposal methods for discarded tire rubber?

Waste tire rubber can be processed through various methods to achieve effective resource utilization and environmental protection. Here are some common handling methods:

1. Renovation and reuse:

For tire rubber products with less wear and tear, such as tires, after professional testing and processing, they can be refurbished and put back into use.

This method extends the service life of tires, reduces the production demand for new tires, and thus lowers resource consumption.

2. Rubber recycling:

Crush and process waste tire rubber, extract its rubber components, and use them to manufacture new rubber products such as rubber floor tiles and rubber tracks.

This method achieves the reuse of resources, reduces the accumulation of solid waste, and lowers the demand for new rubber raw materials.

3. Thermal energy utilization:

By burning waste tire rubber to obtain heat energy, it can be used for power generation or heating.

However, it should be noted that this method requires strict environmental measures to control exhaust emissions and prevent air pollution.

4. Building material:

Processing tire rubber into rubber particles for asphalt modification in road construction to improve road durability and crack resistance.

This method not only utilizes waste tire rubber, but also enhances the quality of the road.

5. Production of rubber powder:

Using mechanical force to crush and grind old tire rubber to obtain rubber powder.

Rubber powder, due to its excellent physical properties, has a wide range of applications. It can be used in the production of tires, rubber shoes, and other rubber products. It can also be mixed with asphalt or cement to make road paving materials, as well as to manufacture various new building and industrial materials.

6. Separation and reuse:

By using advanced technologies such as electromagnetic shock, the rubber in the tire rubber is separated from the metal.

The separated rubber and metal retain their original characteristics and functions, and can be reused in the production of tires or other products.

In summary, there are various methods for treating waste tire rubber, each with its unique advantages and applicable scenarios. In practical applications, the most suitable processing method should be selected according to the specific situation to achieve maximum resource utilization and environmental protection. At the same time, with the advancement of technology and the improvement of environmental awareness, there will be more innovative treatment methods emerging in the future, providing more choices for the disposal of waste tire rubber.
