Australia’s mining industry generates over 12 million waste tyres annually from some of the world’s largest mining equipment. From the massive 400-tonne haul trucks operating across Western Australia’s iron ore mines to the dragline equipment in Hunter Valley coal operations, the scale of tyre waste created by Australian mining is unlike almost anywhere else on earth.
Three things make Australian mining a genuinely distinct challenge for OTR tyre processing: the sheer size of the tyres involved, the remote locations where mines operate, and the volume of equipment running continuously across multiple sites. Any processing solution has to be built around these realities, not around average-case assumptions.
Gradeall International is a manufacturer of tyre recycling equipment based in Dungannon, Northern Ireland, exporting to over 100 countries, including mining operations across Australia. The equipment range includes OTR tyre processing systems, truck tyre sidewall cutters, and tyre balers, all engineered with large-format tyre applications in mind.
Australian mining operations don’t just produce large volumes of waste tyres. They produce tyres that are, in many cases, the largest commercial tyres manufactured anywhere in the world. Processing those tyres on-site, at remote locations, under extreme climatic conditions, requires a different approach to the standard waste tyre management systems designed for urban recycling facilities.
Understanding what makes Australian mining distinct starts with the equipment itself.
The largest haul trucks operating in Australian iron ore and coal mines carry payloads of up to 400 tonnes. The tyres fitted to these vehicles are proportionally enormous.
A single tyre from an ultra-class haul truck can weigh over five tonnes and stand more than four metres tall. Processing a tyre of that scale requires equipment built specifically for the task. A standard car tyre baler or even a truck tyre processing unit is not rated for tyres of this size. Gradeall’s OTR tyre cutting range is designed to handle these dimensions, covering the full spectrum from truck tyres through to the very largest mining formats.
Common ultra-class haul truck models operating in Australian mines include vehicles from Caterpillar’s 797 series, Liebherr’s T 284, and Komatsu’s 980E series. All run tyres in the 53/80R63 to 59/80R63 size range, demanding processing equipment with the structural capacity to match.
Haul trucks generate the most visible tyre volumes, but they’re far from the only equipment on a large mine site. Excavators, wheel loaders, dozers, graders, and water trucks all operate on large-format OTR tyres requiring dedicated processing solutions.
Excavators like the Caterpillar 6090 and Komatsu PC8000 use tyres and undercarriage systems requiring separate handling. Wheel loaders in the Caterpillar 994 or Komatsu WA900 class run on tyres that, while smaller than haul truck units, still fall well outside standard commercial tyre processing parameters. Gradeall’s truck tyre sidewall cutter handles mid-range OTR formats, while the dedicated OTR splitter and cutting systems address the largest equipment on-site.
“Mining tyre processing requires understanding both the equipment and the logistics of where it’s operating,” notes Conor Murphy, Director at Gradeall International. “The tyres are large, the sites are remote, and the volumes are substantial. Processing solutions have to be built for all three of those realities simultaneously.”
Australia’s mining operations are distributed across a continent, with major concentrations in Western Australia, Queensland, and New South Wales. Each region presents its own combination of tyre types, volumes, and logistical challenges.
The equipment selection for a Pilbara iron ore operation differs from what’s practical for a Queensland coal mine or a Western Australian goldfields operation, partly because of mine scale, partly because of access and infrastructure, and partly because of the specific equipment fleets in use.
Western Australia’s Pilbara region hosts some of the largest continuous mining operations on earth. BHP and Rio Tinto both operate extensive iron ore mining complexes across tens of thousands of square kilometres, running fleets of hundreds of haul trucks alongside large excavator and loader fleets.
The tyre volumes generated by Pilbara operations are substantial. A single mine site running 200 haul trucks, with each truck cycling through multiple tyres per year, generates a tyre waste stream that is difficult to manage without on-site processing capacity. Transporting whole OTR tyres from a remote Pilbara mine to an urban recycling facility is expensive and logistically complex. Gradeall’s portable tyre baling system reduces transport volume significantly and enables better management of the waste stream close to source, without the infrastructure demands of a permanent installation.
Rio Tinto’s AutoHaul autonomous railway programme and BHP’s autonomous truck fleet demonstrate the sector’s commitment to operational efficiency. Tyre processing follows the same logic: waste managed at the point of generation costs less than waste transported long distances before processing.
Queensland’s Bowen Basin produces over 200 million tonnes of coal annually across a mixture of open-cut and underground operations. The equipment fleets differ from iron ore mining in some respects, with draglines, surface miners, and continuous mining equipment adding variety to the standard haul truck and excavator complement.
Open-cut coal operations in the Bowen Basin run ultra-class equipment comparable to Pilbara iron ore mines. Gradeall’s truck tyre baler is a practical processing option for operations generating consistent volumes of truck-size tyres, while the larger OTR processing range handles the biggest equipment on-site.
The Hunter Valley in New South Wales presents a similar profile. The region’s coal operations have run at scale for decades, and the concentration of mining contractors and service companies around sites like Singleton and Muswellbrook creates a secondary demand for tyre processing capacity beyond the mines themselves.
The goldfields region centred on Kalgoorlie operates at a different scale to the Pilbara, but generates substantial OTR tyre volumes from deep open-pit gold mining operations. The Super Pit at Kalgoorlie, one of the largest open-pit gold mines in the world, runs a continuous fleet of haul trucks and excavators.
Remote goldfields operations around Leonora, Laverton, and Wiluna typically operate fly-in fly-out (FIFO) workforces, which affects how on-site services including waste processing are structured. Compact, self-contained systems suit these environments better than large fixed installations, and equipment like the MK3 tyre baler is well suited to sites where space and infrastructure are limited.
Remoteness is one of the defining operational challenges for Australian mining. Many significant mine sites are hundreds of kilometres from the nearest city, accessible only by unsealed roads or by air. That isolation has direct consequences for tyre waste management.
The standard response to waste tyre accumulation at remote mine sites has historically been stockpiling, with periodic large-scale transport to urban recycling facilities. This approach is costly, creates storage management issues, and adds significantly to the environmental footprint of the mine’s waste operations. According to the Australian Government’s Department of Climate Change, Energy, the Environment and Water, waste tyre management is a priority area under the National Waste Policy, with an emphasis on reducing transport distances and supporting closer-to-source processing.
FIFO operations require services and infrastructure that are either self-contained or deliverable by road freight. Equipment has to arrive fully assembled or in sections that can be installed without specialist civil works.
Gradeall’s portable tyre baling system is designed with exactly this constraint in mind. It can be transported to remote locations, set up without permanent foundations, and operated with a small trained crew. For mines generating moderate OTR tyre volumes, it provides on-site processing capacity that keeps pace with generation and reduces the need for costly whole-tyre transport.
The inclined tyre baler conveyor and TBC8M conveyor systems support throughput on larger installations where volume justifies more permanent equipment and a higher-capacity feed arrangement.
Australian mining operates across climatic extremes. The Pilbara regularly records ambient temperatures above 45°C. Queensland’s Bowen Basin experiences tropical wet seasons with heavy rainfall and high humidity. The goldfields can combine extreme heat with dust conditions that challenge any mechanical system.
Processing equipment deployed to Australian mining sites has to be rated for these conditions. Steel construction, sealed electrical systems, and robust hydraulic components suited to sustained high-temperature operation are not optional features in this market. They’re the baseline for reliable performance.
Australian mining operates under environmental regulations that include obligations around waste management, mine rehabilitation, and site remediation. Tyre stockpiling is increasingly subject to regulatory scrutiny in several Australian states, which adds a compliance dimension to the practical and economic case for on-site processing.
The tyre bales produced by equipment like the MKII tyre baler have documented applications in civil engineering and construction, including use in retaining walls, drainage systems, and embankment reinforcement. Bales produced to consistent density and dimensional standards can support mine site rehabilitation and infrastructure projects, turning a waste stream into a usable material.
Progressive rehabilitation is now a regulatory requirement for most Australian mining operations rather than an end-of-mine commitment. Waste materials generated during operations that can be repurposed within site rehabilitation programmes reduce disposal costs and contribute to rehabilitation targets.
Tyre bales can be incorporated into bunds, access road construction, and drainage management structures within active mine rehabilitation areas. This repurposing approach is well established in European markets and is increasingly applied in Australian mining contexts where engineers are specifying recycled materials within approved rehabilitation plans.
Reducing on-site waste transport contributes directly to carbon footprint calculations, which matter increasingly to mining companies managing sustainability reporting obligations. Processing tyres at the point of generation, rather than transporting whole tyres hundreds of kilometres to processing facilities, reduces fuel consumption and associated emissions across the supply chain.
Equipment lifecycle management is a related consideration. The tyre rim separator enables the steel rim and rubber tyre to be separated cleanly for different processing and recovery routes. Steel recovery from rims has established value, and clean separation improves the economics of the overall waste stream at mine sites where steel recycling infrastructure is accessible.
Choosing the right processing equipment for a mining application comes down to three variables: the size of the tyres being processed, the volume generated per month, and the constraints of the location where processing will happen.
These three factors interact. A very high-volume mine site with permanent infrastructure and good road access can support a larger fixed installation. A remote FIFO operation generating lower volumes needs compact, self-contained equipment. Most Australian mining applications fall somewhere between these two points, which is why understanding the full equipment range matters before specifying a solution.
The table below summarises typical equipment choices by tyre size and operational context:
A useful starting point for equipment selection is calculating the monthly tyre volume from the mine’s fleet, then working backwards to the processing capacity required to keep pace with generation.
A mine running 100 haul trucks, each generating four waste tyres per year, produces around 33 tyres per month requiring OTR-level processing. That’s a manageable volume for a single well-specified processing unit. A larger operation generating 150 or 200 OTR tyres per month needs either a higher-capacity unit or a parallel processing approach.
Gradeall’s equipment range covers throughput from small-scale operations up to high-volume installations. The OTR tyre splitter and the full OTR cutting range support the highest volumes and largest tyre formats, while the portable systems serve operations where volume is lower and mobility matters more.
Australian mining represents a genuine test of any OTR tyre processing system. The tyre sizes, the operational volumes, the remoteness, and the climatic conditions all push equipment well beyond what’s required for standard commercial tyre recycling.
Gradeall International has been manufacturing tyre recycling equipment in Dungannon, Northern Ireland, for nearly 40 years, exporting to over 100 countries. The OTR range has been developed with large-scale and remote applications in mind, and the full product line covers everything from individual sidewall cutters to integrated processing systems for high-volume mine site operations.
If you’re assessing options for waste tyre management at an Australian mining operation, the starting point is understanding your tyre profile: what sizes you’re generating, at what volumes, and what the constraints of your location are. From there, the right equipment configuration becomes straightforward to specify.

PAS 108 is the British Standard governing tyre bales for use in construction. Equipment like the MKII tyre baler can produce bales to PAS 108 dimensional and density specifications.
Gradeall provides spare parts and global technical support. Routine maintenance is handled by trained on-site operators, with Gradeall’s team available for periodic servicing.
A sidewall cutter removes the reinforced bead area to reduce volume. A tyre splitter cuts the full tyre body into sections. Both are often used in sequence for large OTR tyres.
Yes. The agricultural tyre shear handles the large-format bias-ply tyres used in agricultural applications, which differ in construction from radial OTR mining tyres.
In most remote mining scenarios, yes. Processing at the point of generation reduces transport volume and associated costs substantially, which is why on-site solutions are increasingly the preferred approach.
