What Happens to Waste Tires After Pyrolysis Recycling?

Waste tires are a major challenge for waste management due to their durability and complex composition. However, waste tire pyrolysis provides an effective recycling solution by converting tires into valuable products through high-temperature thermal decomposition in an oxygen-free environment.

During the pyrolysis process, waste tires are heated inside a sealed reactor, causing rubber materials to decompose into oil vapor, combustible gas, and solid residues. These materials are then separated and collected through different processing systems.

1. Waste Tire Preparation

Before entering the pyrolysis machine, waste tires may undergo cutting or shredding according to the equipment configuration and feeding requirements.

Proper preparation helps improve feeding efficiency and ensures stable operation. Depending on the reactor design, whole tires, tire pieces, or rubber particles can be processed.

2. Thermal Decomposition in the Pyrolysis Reactor

Prepared waste tires are fed into the pyrolysis reactor and heated under oxygen-free or oxygen-deficient conditions designed for pyrolysis. As the temperature increases, rubber materials undergo thermal decomposition and generate oil vapor, combustible gas, carbon-rich solid residues, and other components.

3. Pyrolysis Oil Recovery

Generated oil vapor passes through the condensation system, where it is cooled and converted into liquid pyrolysis oil. The recovered oil can be used as industrial fuel or further processed through suitable refining equipment, depending on its properties and intended application.

4. Carbon Black and Steel Wire Recovery

After pyrolysis, the remaining solid materials mainly contain carbon-rich residues and recovered steel wire. Carbon black can be collected for further processing and potential applications in rubber products, briquettes, and other industrial materials, depending on its quality. Steel wire separated from waste tires can also be collected and sent for metal recycling.

5. Combustible Gas Recovery and Environmental Treatment

During pyrolysis, combustible gases are generated and can be recovered for use as heating fuel when supported by the equipment design. The remaining process gases are managed through appropriate gas treatment systems to reduce emissions and meet applicable environmental requirements.

In a word, after pyrolysis recycling, waste tires can be converted into valuable products and without second pollution. Here Huayin provides waste tire pyrolysis machines with different processing capacities and equipment configurations to meet various recycling project requirements.
