Vaporization and Condensation: The smaller molecules vaporize and exit the reactor.

These vapors can be directly burned to produce power or condensed into a liquid known as pyrolysis oil or bio oil.

Gas and Solid Residue: Some molecules remain as a gas and can be used as fuel.

The inorganic components of the tire, such as metals and minerals, form a solid residue that can be further processed or disposed of responsibly.

2. Products from Pyrolysis

Pyrolysis Oil: This oil can be used as a fuel in boilers, furnaces, or further refined into diesel-like fuels.

Gas: The gas produced can be used as a clean fuel for the pyrolysis process itself or for other heating applications.

Solid Residue: This includes carbon black and metal, which can be used in various industrial applications or further processed for reuse.

3. Environmental and Economic Benefits

Reduction in Landfill Usage: By converting tires into useful products, the volume of waste sent to landfills is significantly reduced.

Energy Recovery: The process recovers energy from waste tires, turning a potential pollutant into a valuable resource.

Clean Operation: When properly managed, the pyrolysis process produces minimal emissions and waste, making it an environmentally friendly option.

4. Comparison with Other Methods

Landfilling: This method is wasteful and contributes to environmental pollution.
