Military defence tyre disposal presents distinct challenges. Establishments maintain large mixed vehicle fleets that generate significant volumes of end-of-life tyres across multiple tyre categories: standard passenger and light vehicle tyres from support vehicles, truck and commercial vehicle tyres from logistics fleets, and specialist OTR tyres from armoured and all-terrain military vehicles.
On-site tyre processing equipment offers defence establishments a self-contained waste management capability that reduces reliance on external contractors, controls costs, and supports compliance with MOD environmental management objectives under the Defence Estates Environmental Management System.
The tyre waste stream on a large military base reflects the diversity of the vehicle fleet. Administrative and support vehicles generate standard car and van tyres (R13 to R20). Logistics and transport fleet generate truck tyres (R19.5 to R22.5). Heavy equipment transporter (HET) vehicles generate large truck or borderline OTR tyres. Specialist military vehicles, including armoured wheeled platforms, generate significant volumes of run-flat tyres, which have reinforced sidewall construction that requires attention when selecting processing equipment.
Run-flat tyres are standard on many military light vehicle platforms. Their reinforced sidewall construction, designed to allow continued operation after pressure loss, makes them harder to process in standard equipment. A sidewall cutter capable of handling reinforced construction, or a heavy-duty baler with sufficient compression force, is needed for these tyre types. Pre-cutting the sidewalls before baling is the standard approach for high-volume run-flat processing.
The Gradeall Truck Tyre Sidewall Cutter handles truck tyres and reinforced commercial formats, while the
Defence establishments have historically relied on external contractors for tyre disposal, with collection vehicles accessing the site as required. This approach is operationally straightforward but carries several limitations. Contractor vehicle access requires security clearance procedures on every visit, creating administrative overhead. Collection frequency is dictated by contractor availability rather than operational need. Storage requirements between collections are significant, particularly for larger military tyre categories.
On-site processing equipment changes this dynamic. A tyre baler installed in the base vehicle maintenance facility processes tyres as they arise, eliminating accumulation and the associated storage requirements. Baled tyres can be stored compactly and collected less frequently, reducing contractor site visits. The base retains control of the waste stream at all times.
The Ministry of Defence operates under the Defence Environmental Policy and is committed to meeting statutory environmental standards across all estate operations. End-of-life tyre management falls within the controlled waste framework, and MOD establishments are subject to the same permitting and duty-of-care requirements as commercial waste producers under the Environmental Protection Act 1990 and the Environmental Permitting Regulations.
ISO 14001 certification for environmental management systems is maintained across significant portions of the Defence estate through the Defence Estates Environmental Management System. Documented waste management procedures, including tyre disposal records, form part of the evidence base for ISO 14001 compliance. On-site baling with documented output and collection records provides a clear, auditable evidence trail.
Baled tyres going to a licensed tyre recycling operation, with Waste Transfer Notes in place, satisfy the duty-of-care requirements under section 34 of the Environmental Protection Act. The baling process itself does not require an environmental permit; it is the downstream disposal that requires the receiving site to be permitted.
A large Army base or Royal Air Force station with several hundred vehicles will generate a steady throughput of tyres across multiple categories. A typical sizing approach starts with an audit of monthly tyre replacement volumes across the fleet, categorised by tyre type.
For a predominantly light-vehicle fleet generating car and van tyres, the MKII Tyre Baler provides sufficient throughput. For a mixed fleet including commercial vehicle sizes, the Truck Tyre Baler is more appropriate. For bases with significant armoured vehicle or HET fleets generating large-format tyres, an OTR processing capability, including sidewall cutting equipment, is needed ahead of baling.
Gradeall’s tyre recycling equipment range covers the full spectrum from car tyres to OTR categories, with equipment designed to work as an integrated processing line or as standalone units, depending on site requirements.
“We’ve supplied equipment to defence and security sector customers in multiple countries,” says Conor Murphy, Director of Gradeall International. “The common requirement is reliability, clear documentation, and a processing capability that doesn’t depend on external contractors turning up on schedule.”
Some military applications require portable or deployable equipment rather than fixed installations. Gradeall’s portable tyre baling system is designed for this requirement, operating from a standard power supply and capable of relocation within a base or between sites as operational requirements change.
The portable tyre baling system is particularly relevant for forward operating bases, training establishments with temporary tyre stockpiles, and sites where permanent installation is not practical.
No. Tyre baling is not a permitted waste activity in itself. The Environmental Permitting Regulations require permits for waste treatment and disposal operations, but the act of baling tyres on the site where they arise, before transfer to a licensed facility, does not trigger a permit requirement. The receiving facility (the tyre recycler) must be appropriately permitted. The site baling tyres is responsible for applying the waste duty of care when transferring the bales, which means using a registered waste carrier and ensuring Waste Transfer Notes are completed.
Run-flat tyres have reinforced sidewall construction designed to maintain vehicle operation after pressure loss. This reinforcement, typically achieved through self-supporting rubber inserts or pressure-monitoring support rings, makes the tyre harder to compress and more resistant to baling without pre-treatment. For military run-flat tyres, sidewall cutting before baling is the recommended approach. Cutting the sidewalls removes the structural rigidity that resists compression and allows the tyre to be baled at normal force.
It is technically possible to mix tyre sizes in a single bale, but best practice is to separate by category, particularly separating car tyres from truck tyres and OTR from commercial categories. Mixed bales are harder to recycle efficiently and may be refused by some recycling facilities. If the downstream recycler requires separated inputs, on-site separation before baling is the correct approach.
Standard Gradeall tyre balers operate from three-phase 415V power supply, which is available at most permanent military installations. For deployable or temporary applications, single-phase variants or generator-compatible models are available. Confirm the available power infrastructure at the installation point before specifying equipment.
The MOD’s Sustainability and Climate Change Strategy sets targets for waste diversion from landfill and carbon reduction across the defence estate. Baling tyres for recycling contributes directly to waste diversion metrics. On-site processing also reduces the transport movements associated with loose tyre collection, with a corresponding reduction in associated transport emissions. Documented recycling tonnages from baling programmes can be reported through base environmental management systems as evidence of progress against sustainability targets.
