Tyre pyrolysis is a process that converts waste tyres into valuable resources.
The end products of tyre pyrolysis include pyrolysis oil, carbon black, steel wire, and gas.
Each of these products has unique properties and uses, contributing to the overall value and environmental benefits of the pyrolysis process.
5 Key Products of Tyre Pyrolysis
1. Pyrolysis Oil
Pyrolysis oil is characterized by its low viscosity and high calorific value.
This makes it a viable fuel option for various industries.
It can be directly burned in cement kilns, paper mills, power plants, industrial furnaces, foundries, and boilers.
This is due to its high energy content and low ash, residual carbon, and sulfur content.
Additionally, the oil can be further distilled to extract even more value from it.
2. Carbon Black
Carbon black is produced in significant quantities during tyre pyrolysis.
It is a high-quality material with a wide range of applications.
Carbon black is used in the production of tires, rubber products, inks, and asphalt modifiers.
The economic yield from carbon black can even surpass that of pyrolysis oil.
This highlights its importance in the pyrolysis process.
3. Steel Wire
The steel wire recovered from tyres can be repurposed into various steel materials.
These include metal abrasives and steel wire cut shots.
This recycling of steel not only reduces waste but also provides a resource for manufacturing industries.
4. Gas
The gas produced during tyre pyrolysis typically contains about 40% methane.
This gas is a valuable by-product.
It can be utilized as a fuel source or for other industrial processes.
This contributes to the overall efficiency and sustainability of the pyrolysis operation.
5. Syngas
At higher temperatures, above 700°C, the pyrolysis process can yield synthetic gas (syngas).
Syngas is a mixture of hydrogen and carbon monoxide.
This product can be used in various industrial applications, further enhancing the value of the pyrolysis process.
The Pyrolysis Process
The pyrolysis process involves heating tyres in a sealed reactor under controlled conditions.
This breaks down the rubber into various components.
The specific products and their qualities are influenced by factors such as the temperature, the nature of the feedstock (whether whole or shredded tyres), and the pyrolysis methods used.
Environmental and Economic Benefits
Tyre pyrolysis is a complex process that not only helps in managing waste tyres but also converts them into valuable resources.
This promotes a circular economy and environmental sustainability.
