Tyre recycling is expanding as disposal fees increase, landfill regulations tighten, and downstream demand for rubber granules, recovered steel, and alternative fuels continues to grow.
This article outlines each step of the tyre recycling process and explains how tyre balers, primary shredders, secondary wire separators, and tertiary granulators operate within different plant configurations and business models.
Tyre Recycling Process: Step-by-Step
Step 1: Waste Tyre Collection and Pre-Sorting
Every tyre recycling project starts with collecting end-of-life tyres from various sources. You may obtain waste tyres from tyre shops, vehicle fleets, transfer stations, municipal collection points, or independent traders.
Once the tyres arrive at your facility, they are sorted according to size, type, and condition. Separating passenger tyres from truck or off-road tyres helps create a more efficient processing flow.
At this stage, obvious contaminants should also be removed. Metal rims, rocks, and other foreign materials can damage equipment and increase maintenance costs if they enter the recycling line. A thorough pre-sorting process helps you protect downstream machinery and ensures a more stable production operation.
Step 2: Tyre Baling: Compressing for Transport and Storage
Waste tyres are bulky and difficult to transport efficiently. If you need to move large volumes of tyres over long distances or store them before processing, tyre baling can significantly reduce handling costs.
A Tyre Baler uses hydraulic pressure to compress loose tyres into dense, compact bundles. Steel wires are then applied to secure the bale and maintain its shape during transportation and storage. By increasing loading density, you can fit more material into each truck or container. This helps lower transportation costs per ton and improves overall logistics efficiency.
Step 3: Feeding Loose or Baled Tyres to the Line
Before processing begins, tyres must be introduced into the recycling system at a controlled rate. Depending on your facility layout, feeding may be performed using conveyors, loaders, or other material handling equipment.
If the tyres arrive in compressed bales, they are first unpacked before entering the line. Loose tyres can then be transferred directly to the feeding section.
A final visual inspection is usually performed during this stage. Removing oversized contaminants before shredding helps prevent equipment damage and production interruptions.
Step 4: Primary Size Reduction: Dual-Shaft Tyre Shredder (<100 mm)
Primary shredding is the first major size reduction stage in a tyre recycling plant. Whole tyres are fed into a Dual-shaft Tyre Shredder, where they are torn into smaller pieces through powerful shearing action.
Inside the cutting chamber, two counter-rotating shafts grip the tyres and gradually pull them into the cutters. Rather than relying on high-speed impact, the machine uses a low-speed, high-torque design to process tough rubber and embedded steel reinforcement.
After shredding, the material is typically reduced to tyre chips smaller than 100 mm. These chips are easier to handle and provide an ideal feedstock for downstream wire separation and granulation equipment.
The shredded tyre chips are then processed by a Tire Wire Separator. At this stage, the goal is to further reduce particle size while separating steel wire from the rubber. The machine combines additional cutting action with mechanical wire liberation. As the material becomes smaller, steel reinforcement is gradually released from the surrounding rubber.
Integrated magnetic separation systems continuously remove the liberated steel during operation. This improves steel recovery while producing a cleaner rubber fraction for the next processing stage.
By the end of this step, the material is typically reduced to less than 15 mm. The cleaner rubber chips are then ready for final granulation.
Step 6: Tertiary Reduction: Rubber Granulator for Fine Granules (<5 mm)
If you want to produce higher-value rubber granules, the material must undergo further size reduction. This is where the Rubber Granulator plays a key role.
The granulator uses high-speed rotating knives and stationary cutting blades to continuously reduce rubber chips into smaller particles. Precise cutting helps produce a more uniform final product.
A closed-loop screening system controls the output size. Particles that do not meet the target specification are automatically returned to the granulator for additional processing. The final product is typically smaller than 5 mm and can be used in applications such as rubber flooring, sports surfaces, molded rubber products, or further powder production.
Step 7: Screening, Fiber Separation, and Final Cleaning
Although most steel is removed earlier in the process, small amounts of fiber and residual metal may still remain in the material. Additional cleaning equipment is therefore used to improve product quality.
Vibrating screens separate the rubber into different size fractions according to market requirements. Depending on your target application, you may produce coarse chips, granules, or finer crumb rubber products.
Air separation systems remove lightweight textile fibers from the rubber stream. Additional magnetic separators capture any remaining metal fragments that may still be present. The result is a cleaner, more consistent rubber product that meets the quality standards required by downstream buyers.
Step 8: Final Product Collection and Storage
After processing is complete, the recovered materials are collected and stored separately. Rubber granules, steel wire, and textile fiber are typically conveyed to dedicated storage areas for easier handling and sale. Depending on plant capacity, storage systems may include silos, bunkers, hoppers, or bulk bags. Proper storage helps maintain product quality and improves inventory management.
Organized storage also simplifies loading operations and prepares the materials for shipment to end users. At this point, the recycling process is complete and the recovered resources are ready to re-enter the manufacturing supply chain.
In a typical Tyre Recycling Plant, tyres move progressively through baling, shredding, wire separation, granulation, and cleaning stages. Each step reduces particle size, improves material purity, and increases the value of the final recycled products.
Main Output Materials from a Tyre Recycling Line
1. Rubber Chips
Rubber chips are typically produced after the primary shredding stage. They are often used as feedstock for further processing or as tire-derived fuel in industrial applications.
2. Rubber Granules and Crumb Rubber
Rubber granules are produced after secondary shredding, granulation, and cleaning. They can be used in sports surfaces, playground flooring, rubber products, and asphalt modification.
3. Recovered Steel Wire
Steel wire is separated from the rubber during the wire liberation process. The recovered steel can be sold to metal recyclers and reintroduced into the steel manufacturing supply chain.
4. Textile Fiber
Textile fiber is removed during the final cleaning stage. Although it has a lower market value than rubber or steel, it can still be reused in certain industrial applications or alternative fuel systems.
The value of a tyre recycling operation depends not only on processing capacity but also on how effectively these recovered materials are cleaned, separated, and marketed.
FAQs
Q: How much rubber can be recovered from a waste tyre?
A: The exact yield depends on tyre type and processing depth, but passenger and truck tyres generally contain a high proportion of recoverable rubber.
Q: What factors affect the profitability of tyre recycling?
A: Profitability is influenced by local tyre supply, transportation costs, tipping fees, energy consumption, labor costs, and the market value of recovered rubber and steel. Plants that produce higher-value granules often achieve better margins than those selling only tyre chips.
Q: Can all types of tyres be recycled?
A: Most passenger car, truck, bus, and off-road tyres can be recycled. However, very large mining tyres or heavily contaminated tyres may require specialized handling or dedicated processing equipment.
Q: What is the typical starting capacity for a tyre recycling line?
A: Many plants start in the 1–3 t/h range, which is enough to handle regional tyre volumes while keeping investment and operating complexity under control. As feedstock and sales grow, additional machines or parallel lines can be added to increase capacity.
Q: How long does it take to process a batch of tyres?
A: Processing time depends on equipment capacity, tyre size, and the target output specification. Modern continuous recycling lines are designed to maintain a steady material flow and minimize production interruptions.
