Every year, approximately 300 million used car tyres are discarded worldwide, creating a massive environmental challenge. Rather than allowing these tyres to pile up in landfills or illegal dumps, recycling offers a sustainable solution that transforms this waste into valuable resources.
A sustainable Living Initiative has been at the forefront of educating consumers about responsible tyre disposal options that protect our environment while creating new products.
The journey of a recycled tyre is remarkable – from worn rubber that once traversed thousands of miles to becoming playground surfaces, garden planters, or even components in new roads. Understanding how this transformation happens and why it matters is the first step toward making responsible choices with your old tyres.
Recycle Car Tyres – Why Old Tyres Are an Environmental Nightmare
Discarded tyres present several serious environmental and health hazards when improperly disposed of. They take up valuable landfill space and their unique shape allows them to trap air, water, and even gases, making them prone to rising to the surface and damaging landfill liners. When abandoned in piles, they quickly become breeding grounds for mosquitoes and rodents that can spread diseases to surrounding communities.
Fire Hazard
Perhaps most alarmingly, tyre piles present significant fire hazards. Once ignited, tyre fires are exceptionally difficult to extinguish and can burn for months, releasing toxic chemicals including carbon monoxide, sulfur dioxide, and oils that contaminate air, soil, and groundwater. A single burning tyre can release over two gallons of oil, and the black smoke contains particulate matter that causes respiratory issues.
Environmental Hazard
The environmental impact extends to the waste of valuable materials. Tyres contain rubber, steel, fiber, and other compounds that require significant resources to produce. When dumped rather than recycled, these materials and the energy used to create them are lost forever instead of being recovered in the circular economy.

5 Best Methods for Car Tyre Recycling
The recycling industry has developed several effective methods to process used tyres, each with unique advantages and applications. These technologies allow for the recovery of valuable materials while minimizing environmental impact. The method chosen depends on factors like local infrastructure, economic considerations, and the desired end products.
1. Mechanical Recycling: Grinding Tyres into Rubber Crumb
Mechanical recycling is the most common method used worldwide, involving the physical breakdown of tyres into smaller pieces without changing their chemical composition. The process begins with whole tyres being fed into powerful shredders that reduce them to chips typically 2 inches or smaller in size. These chips then pass through granulators that further reduce their size while separating the rubber from steel and fiber components using magnets and air classification systems. The result is rubber crumb of various sizes that can be used in numerous applications, including playground surfaces, athletic fields, and asphalt modification for roads.
2. Pyrolysis: Converting Tyres into Fuel and Carbon
Pyrolysis offers an innovative approach to tyre recycling by thermally decomposing rubber in an oxygen-free environment. This advanced process breaks down tyres at temperatures between 400-700°C, transforming the rubber compounds into valuable byproducts without combustion. The absence of oxygen prevents burning while allowing molecular breakdown of the complex rubber polymers. For more detailed information on tyre recycling methods, visit this comprehensive guide.
A Valuable Product – Pyrolytic Oil
The process yields several commercially valuable products. Pyrolytic oil, similar to industrial fuel oil, can be refined further or used directly as fuel. Carbon black, which comprises about 30% of the output, serves as a reinforcing agent in new rubber products or as pigment. Steel wire is recovered intact and can be recycled in traditional metal recycling streams. Additionally, the process produces synthetic gas that can be captured and used to power the pyrolysis operation itself, improving energy efficiency.
While pyrolysis requires significant upfront investment in specialized equipment, it represents one of the most complete recovery methods available. Modern facilities can process up to 20,000 tons of tyres annually with minimal emissions when properly operated, making it increasingly attractive as technology advances and scales.
3. Retreading: Giving Tyres a Second Life
Retreading extends the useful life of tyre casings by replacing only the worn tread rather than discarding the entire tyre. This resource-efficient process begins with a thorough inspection of the used tyre casing to ensure structural integrity. Any damaged casings are rejected and sent for other recycling methods.
Approved casings undergo buffing to remove remaining tread and prepare the surface for new rubber application. New tread rubber is then precisely applied to the prepared casing using heat and pressure to create a molecular bond. Modern retreading technologies utilise computerised equipment to ensure uniformity and quality comparable to new tyres. The finished retreaded tyre undergoes rigorous testing before returning to service.
Commercial Truck and Aircraft Tyres
This method is particularly popular for commercial truck and aircraft tyres, where it reduces raw material usage by up to 70% compared to manufacturing new tyres. While passenger vehicle tyres are less commonly retreaded due to economic factors, the process represents one of the most resource-efficient approaches to tyre lifecycle management when applicable.
4. Devulcanization: Breaking Down Rubber for Reuse
Devulcanization tackles one of the most challenging aspects of rubber recycling by reversing the chemical process that gives tyres their durability. During tyre manufacturing, rubber compounds are vulcanized—heated with sulfur to create cross-linked molecular structures that provide strength and elasticity. This chemical transformation was historically considered irreversible, limiting recycled rubber's applications.
Devulcanization Technologies
Modern devulcanization technologies use combinations of heat, chemicals, microwaves, or ultrasonic energy to selectively break the sulfur bonds without damaging the polymer chains. The resulting material regains many properties of virgin rubber and can be incorporated into new rubber products at higher percentages than traditional recycled rubber crumb. This breakthrough allows recycled rubber to partially replace virgin materials in manufacturing new tyres and high-performance rubber products.
While still evolving and scaling commercially, devulcanization represents a significant advancement toward true circular economy for rubber products. Research continues to improve efficiency and quality, with some processes now achieving up to 80% recovery of original rubber properties.
5. Energy Recovery: Using Tyres as Fuel
Tyre-derived fuel (TDF) utilizes the high energy content of rubber as an alternative to coal or other fossil fuels. With a calorific value of approximately 14,000 BTUs per pound—higher than most coals—tyres provide efficient energy when properly combusted. Modern facilities shred tyres to consistent sizes that optimize burning efficiency while sophisticated emission control systems capture potential pollutants. For more on recycling and waste management, check out these 10 ways to reduce, reuse, and recycle.
Co-firing in Cement Kilns
This method is particularly common in cement kilns, where the extremely high operating temperatures (1400-1500°C) ensure complete combustion while the steel components in tyres provide iron needed in cement production. Paper mills, power plants, and industrial boilers also utilize TDF to reduce their dependency on traditional fossil fuels. The controlled environment of these industrial facilities allows for much cleaner burning than tyre fires, with emissions comparable to or better than coal.
While energy recovery ranks lower than material recycling in the waste hierarchy, it provides a valuable solution for tyres that cannot be recycled through other methods. Modern facilities can recover up to 25% more energy from tyres than from coal per unit weight, while reducing net carbon emissions when displacing virgin fossil fuels.
