How do you recycle end of life tyres(ELTs)? What are options for tyre recycling ways?

Recycling end-of-life tyres (ELTs) is an important process aimed at reducing waste and repurposing materials. There are several methods and options for tyre recycling, each with its own advantages and applications. Here are the primary ways ELTs can be recycled:

1. Shredding and Grinding: Tyres are first shredded into smaller pieces known as chips or crumbs. These can further be ground into fine rubber powder. The resulting material finds use in various applications, including playground surfaces, running tracks, and asphalt mixtures for roads.

However, this kind of mechanical recycling has its limitations. The quality of the recycled rubber obtained may not be as high as that of virgin rubber, and it often requires a large amount of energy and complex processing steps to achieve the desired particle size and quality.

2. Pyrolysis: A thermal decomposition process carried out in the absence of oxygen, pyrolysis breaks down end of life tyres(ELTs) into their basic components—oil, gas, carbon black, and steel. Here is a 3D animation videos to help you have a better understanding of tire to fuel oil recycling pyrolysis process:

Through above pyrolysis process, the pyrolysis oil extracted from tyre recycling pyrolysis machine is a kind of very good heating fuel, with 10592.48Kcal/kg heating value, which is much higher than that of coal. It has a good market in different countries. The fuel oil, tire pyrolysis oil(TPO) is widely used in boiler factory, cement factory, steel factory, brick factory, glass factory, heavy oil power plant, warm supply center and so on. The oil can be refined into diesel fuel by waste oil distillation plant, gas can be used as an energy source to heat the pyrolysis plant directly, char (carbon black) has industrial uses, and steel wire is recycled.

Tyre pyrolysis is a relatively clean and efficient process, with lower environmental impacts compared to some other methods. It also has the potential to generate significant economic returns as the byproducts have a wide range of market applications. Therefore, tyre recycling pyrolysis machine offers a unique and highly promising solution.

3. Cement Kiln Fuel: Whole or shredded tyres can be used as an alternative fuel source in cement kilns. They provide a high-calorific value and reduce the reliance on fossil fuels. However, this method, which is equivalent to directly burning end of life tyres(ELTs), is relatively polluting, and the smoke it produces has complex components and a strong odor, posing a threat to the environment and the personal safety of factory personnel.

Each method has different economic and environmental implications, and the choice often depends on local market conditions, available technology, and regulatory frameworks. It's crucial to conduct a thorough analysis before selecting the most suitable recycling approach.
