Mining Tyre Waste: Managing Haul Truck and Earthmover Tyres at Mine Sites

By:   author  Kieran Donnelly
Expert review by:   Conor Murphy  Conor Murphy

Mining operations generate enormous end-of-life tyres from haul trucks, excavators, loaders, and support vehicles. A single Caterpillar 797F haul truck tyre weighs 5,500kg and stands 4 metres tall. These Off-The-Road (OTR) tyres cannot be processed by standard tyre recycling equipment designed for car and truck tyres.

Mine sites face unique challenges: remote locations (limited access to waste processors), large tyre volumes (50-200 OTR tyres plus 500-1,000 light vehicle tyres annually at typical surface mine), size and weight (individual tyres weighing 1,000-6,000kg), steel content (40-50% by weight in large OTR tyres), and environmental obligations (mining permits require waste management plans).

Improper tyre management creates problems: stockpiles occupying productive land, fire risks (tyre fires at mine sites catastrophic), environmental violations (regulatory penalties, permit conditions), and lost value (tyres have recovery value if properly processed).

This guide explains OTR tyre characteristics, processing options for mine sites, equipment requirements, logistics considerations, and cost-effective waste management strategies.

OTR Tyre Categories at Mining Sites

Haul truck tyres (ultra-class and large mining trucks):

  • Vehicles: Caterpillar 797F, Komatsu 980E, Liebherr T 284
  • Tyre size: 55/80R63 to 59/80R63 (4.0-4.3 metres diameter)
  • Weight per tyre: 4,500-6,000kg
  • Steel content: 1,800-2,700kg per tyre (40-45%)
  • Rubber content: 2,700-3,300kg per tyre
  • Lifespan: 3,000-8,000 hours depending on conditions
  • Annual disposal (200-truck fleet): 30-60 tyres

These are the largest tyres on site and most challenging to process. Cannot be moved without specialized equipment.

Rigid dump truck tyres (articulated and rigid haulers):

  • Vehicles: Caterpillar 777, Volvo A60H, Komatsu HD785
  • Tyre size: 33.00R51 to 40.00R57 (2.5-3.2 metres diameter)
  • Weight per tyre: 1,500-3,500kg
  • Steel content: 600-1,400kg per tyre (40%)
  • Rubber content: 900-2,100kg per tyre
  • Lifespan: 4,000-10,000 hours
  • Annual disposal (50-vehicle fleet): 40-80 tyres

More numerous than ultra-class but individually smaller. Still require specialized handling.

Loader and excavator tyres:

  • Vehicles: Caterpillar 992, Komatsu WA800, Liebherr R 996
  • Tyre size: 33.00R51 to 37.00R57 (2.0-2.8 metres diameter)
  • Weight per tyre: 1,200-2,000kg
  • Steel content: 480-800kg per tyre (40%)
  • Rubber content: 720-1,200kg per tyre
  • Lifespan: 5,000-12,000 hours (less abrasive duty than haul trucks)
  • Annual disposal (20-vehicle loader fleet): 30-50 tyres

Light vehicle fleet tyres (support vehicles, utilities, personnel):

  • Vehicles: Toyota Land Cruiser, pickup trucks, service vehicles
  • Tyre size: 245/75R16 to 33×12.50R20 (standard light truck sizes)
  • Weight per tyre: 15-35kg
  • Annual disposal (200-vehicle light fleet): 600-1,000 tyres

These can be processed using standard truck tyre equipment if volumes justify on-site processing.

On-Site vs Off-Site Processing

Off-site disposal (most common):

Tyres transported to specialized processors for cutting, shredding, or recovery.

Logistics:

  • Ultra-class tyres: Low-loader transport (£800-£2,000 per load, 1-2 tyres per load)
  • Rigid dump tyres: Flatbed or low-loader (£600-£1,500 per load, 3-6 tyres per load)
  • Light fleet: Standard articulated lorry (£400-£800 per load, 80-120 tyres per load)

Processing costs:

  • Tipping fee: £200-£400 per tonne for OTR tyres (£300-£2,400 per ultra-class tyre)
  • Steel recovery credit: £100-£200 per tonne steel extracted (offsets 20-40% of tipping fee)
  • Net cost: £150-£300 per tonne (£675-£1,800 per ultra-class tyre)

Annual cost (typical surface mine, 60 OTR tyres + 800 light fleet tyres):

  • OTR disposal: 150 tonnes × £250/tonne = £37,500
  • Light fleet disposal: 8 tonnes × £180/tonne = £1,440
  • Transport: £45,000-£60,000 Total: £83,940-£98,940 annually

On-site processing:

Install cutting equipment at mine site to reduce tyre volume before transport or enable local disposal.

Equipment options:

  • OTR tyre shear (£120,000-£250,000): Cuts ultra-class tyres into quarters
  • Mobile cutting system (£80,000-£150,000): Transported to tyres, cuts in situ
  • Standard sidewall cutter (£18,000-£35,000): Processes light fleet and small OTR

Benefits:

  • Reduced transport cost: Quartered tyres stack efficiently (4× volume reduction)
  • Local disposal options: Cut tyres used on-site (erosion control, drainage)
  • Steel recovery: Separate steel at point of generation (higher value)
  • Scheduling control: Process tyres as generated (no stockpiling)

Investment consideration: At 60 OTR tyres annually, off-site disposal costs £83,000-£99,000. On-site equipment costs £120,000-£250,000 capital plus £15,000-£30,000 annual operating costs. Break-even: 2-4 years depending on equipment choice and transport distance.

For mines generating 100+ OTR tyres annually or located over 200km from processors, on-site processing economics improve significantly.

OTR Tyre Cutting Methods

Quartering (sectioning):

Divide tyre into 4-8 pieces using hydraulic shear or cutting equipment.

Process:

  1. Position tyre horizontally
  2. Cut radially from outer tread to inner bead (4 cuts creating 4 sections)
  3. Remove steel bead wires from each section
  4. Stack quartered sections for transport or on-site use

Equipment: Hydraulic shear with 200-300 tonne cutting force, articulated arm positioning Cycle time: 15-30 minutes per ultra-class tyre (4 cuts plus positioning) Output: 4 sections per tyre, each 1,000-1,500kg

Advantages:

  • Reduces volume 75% (4 stacked sections vs whole tyre)
  • Enables transport (sections fit standard flatbed)
  • Opens access to steel for recovery

Disadvantages:

  • Expensive equipment (£120,000-£250,000)
  • Requires skilled operator
  • Slow for high volumes

Radial cutting (segmenting):

Cut tyre into multiple narrow segments (8-16 pieces) for easier handling.

Process:

  1. Position tyre vertically
  2. Make radial cuts from tread to bead (every 45° = 8 segments, every 22.5° = 16 segments)
  3. Segments fall away as cut
  4. Bead wires remain as ring structure (separate processing)

Equipment: Hydraulic shear or cutting torch Cycle time: 25-45 minutes per ultra-class tyre Output: 8-16 segments, each 300-750kg

Advantages:

  • Smaller pieces easier to handle
  • Better for on-site reuse (smaller segments)
  • Steel beads separate easily

Disadvantages:

  • More cuts required (longer cycle time)
  • Generates more pieces to manage

Sidewall removal (for medium OTR):

For 1,500-3,000kg OTR tyres (rigid haulers, large loaders), standard sidewall cutting viable.

Process:

  1. Position tyre in cutter
  2. Remove both sidewalls (leaves tread section)
  3. Tread section compacts more readily than whole tyre
  4. Sidewalls processed separately

Equipment: Heavy-duty sidewall cutter (£25,000-£45,000) Cycle time: 3-5 minutes per tyre (both sidewalls) Output: Tread section (60% of weight) + 2 sidewalls (40% of weight)

Advantages:

  • Fast processing
  • Enables volume reduction
  • Standard equipment (lower cost)

Disadvantages:

  • Only suitable for smaller OTR (under 3,000kg tyres)
  • Ultra-class tyres too large for this method

On-Site Tyre Reuse Options

Cut tyres have multiple uses within mining operations, reducing or eliminating disposal costs.

Erosion control:

Quartered tyre sections placed on slopes prevent soil erosion from rainfall runoff.

Application:

  • Cut sections into 500-800kg pieces
  • Position on slopes requiring stabilization
  • Anchor with ground stakes or buried portion
  • Vegetation grows through sections (eventual integration)

Volume: 10-15 tyre sections per 100 metres of slope Lifespan: 15-25 years before rubber degrades Cost saving: £100-£200 per tyre vs off-site disposal

Regulatory: Check mining permit conditions (some jurisdictions classify this as waste disposal requiring approval)

Drainage material:

Tyre pieces create effective drainage layers in haul roads and access routes.

Application:

  • Shred or cut tyres into 100-300mm pieces
  • Place as drainage layer beneath road surface (300-500mm depth)
  • Voids between rubber pieces allow water drainage
  • Reduces road maintenance from water damage

Volume: 1 tyre per 2-3 square metres of road (300mm depth) Benefit: Reduces haul road maintenance costs £5,000-£15,000 per kilometre annually Lifespan: 10-15 years in drainage application

Blast protection barriers:

Whole or halved tyres create protective barriers around infrastructure.

Application:

  • Stack tyres 2-3 high around fuel tanks, substations, buildings
  • Fill tyres with soil or gravel for stability
  • Provides blast and projectile protection

Volume: 20-40 tyres per 10-metre barrier section Benefit: Protects high-value infrastructure (fuel farms, electrical equipment) Alternative cost: Concrete barriers £300-£500 per metre

Road widening and filling:

Tyres used as void fill for road widening or level areas.

Application:

  • Place whole tyres in void areas requiring fill
  • Backfill around tyres with waste rock or soil
  • Compact to create stable surface
  • Build road or platform on top

Volume: 50-100 tyres per 100 cubic metres of void fill Benefit: Free fill material (vs purchasing rock or importing soil) Consideration: Not suitable for all ground conditions (requires engineering assessment)

Weighing on-site reuse:

Advantages: Zero disposal cost, productive use of waste material, reduces transport impact Disadvantages: Not all jurisdictions permit on-site reuse (check regulations), eventual degradation creates long-term liability, limits capacity (only reuse 20-40% of generated tyres typically)

Best approach: Combine on-site reuse (where viable) with off-site recycling (for remainder).

Light Fleet Tyre Management at Mines

Mine sites operate 100-300 light vehicles (pickups, utilities, personnel transport) generating 600-1,200 conventional tyres annually.

Processing options:

On-site baling: If volumes exceed 25,000 tyres annually (considering potential off-site collection from nearby operations), install tyre baler.

Equipment: MKII baler (£50,000-£65,000) Capacity: 80 tyres per hour Output: 900-1,000kg bales suitable for construction market Annual operating cost: £12,000-£18,000

At 1,000 tyres annually:

  • Processing time: 12.5 hours annually
  • Bale output: 12 bales (12 tonnes)
  • Revenue: 12 tonnes × £120/tonne = £1,440
  • Net cost: £10,560-£16,560 annually

Compare to off-site disposal:

  • Current cost: 10 tonnes × £180/tonne + £1,500 transport = £3,300 annually

Baling doesn’t justify investment at 1,000 tyres annually. Break-even around 15,000-20,000 tyres annually.

Consolidation with off-site light fleet operators:

If mine is near other operations (multiple mines in district, industrial estates), consolidate light fleet tyres for shared processing.

Example: 3 mines in 50km radius, 1,000 tyres each = 3,000 tyres aggregated Shared baler: £55,000 cost ÷ 3 = £18,333 per site Operating cost: £5,000-£7,000 per site annually

This shared model makes baling viable at smaller individual volumes.

Standard disposal:

For isolated mines with under 1,500 light fleet tyres annually, standard disposal via contractor most cost-effective.

Regulatory Compliance for Mining Tyre Waste

Mining permit conditions:

Mining permits (issued by minerals authorities) include waste management requirements. Tyres typically addressed under:

Waste management plan: Describe tyre handling, storage, disposal Environmental monitoring: Track tyre quantities, disposal methods, destinations Closure planning: Address tyre stockpiles in mine closure plan

Failure to comply: Permit violations (£20,000-£500,000 penalties), permit suspension (halts operations)

Environmental permits:

If storing over 40 tonnes tyres on site: Environmental permit required (in England/Wales, Environment Agency regulations)

Exemption T9: Under 40 tonnes, free registration Standard permit: 40-1,000 tonnes, £1,650+ application, £1,161+ annual fee Bespoke permit: Over 1,000 tonnes, £13,000+ application

Duty of care:

Transfer tyres only to authorized waste carriers and processors. Obtain waste transfer notes for every movement. Retain records 2 years minimum.

Prosecution for illegal waste transfer: £50,000 unlimited fines, potential imprisonment for systematic violations

On-site reuse approvals:

Using cut tyres for erosion control, drainage, or fill may require:

  • Environmental permit variation (if on-site reuse classified as disposal)
  • Engineering certification (structural fill applications)
  • Regulatory approval (some jurisdictions prohibit tyre fill)

Consult environmental regulator before implementing on-site reuse programs.

Cost-Benefit Analysis: On-Site Processing

Scenario: Medium surface mine, 60 OTR tyres + 800 light fleet tyres annually

Current off-site disposal:

  • OTR transport: £50,000
  • OTR tipping: £37,500
  • Light fleet transport: £1,500
  • Light fleet tipping: £1,440 Total: £90,440 annually

Option A: On-site OTR cutting (mobile system, £130,000 capital):

  • Equipment amortization (10 years): £13,000 annually
  • Operating costs: £18,000 annually
  • Reduced transport (quartered): £15,000 (70% reduction)
  • Reduced tipping (volume reduction): £22,500 (40% reduction, less steel to dispose)
  • Light fleet (unchanged): £2,940
  • Total annual cost: £71,440 Saving: £19,000 annually (21% reduction) Payback: £130,000 ÷ £19,000 = 6.8 years

Option B: On-site reuse of 30% + off-site remainder:

  • Reuse program costs: £8,000 annually (equipment rental, labour)
  • OTR off-site (70% of original): £61,250
  • Light fleet (unchanged): £2,940
  • Total annual cost: £72,190 Saving: £18,250 annually (20% reduction) No capital investment

Option C: Combination (cutting + reuse):

  • Equipment: £130,000 capital
  • Operating: £22,000 annually
  • On-site reuse: 40% of tyres (£0 disposal)
  • Reduced off-site: £40,000
  • Total annual cost: £62,000 Saving: £28,440 annually (31% reduction) Payback: 4.6 years

For most mines, combination approach delivers best ROI: Cutting enables both efficient transport and on-site reuse opportunities.

Frequently Asked Questions

How many tyres does a typical mine generate annually?

Surface mine (200-truck ultra-class fleet): 30-60 ultra-class haul truck tyres (4,500-6,000kg each), 40-80 rigid dump truck tyres (1,500-3,500kg each), 30-50 loader/excavator tyres (1,200-2,000kg each), 600-1,000 light vehicle fleet tyres (10-35kg each). Total: 100-190 OTR tyres (150-300 tonnes) plus 600-1,000 light fleet tyres (6-10 tonnes). Underground mines generate fewer OTR tyres (smaller vehicles) but similar light fleet volumes.

What are the disposal costs for ultra-class mining tyres?

Transport: £800-£2,000 per load (1-2 tyres per load due to size/weight). Tipping: £200-£400 per tonne (£900-£2,400 per 4,500-6,000kg tyre). Steel recovery credit: £100-£200 per tonne steel (offsets 20-40% of tipping fee). Net cost per tyre: £675-£1,800. Annual disposal cost (50 ultra-class tyres): £33,750-£90,000. Economies improve with volume and distance to processor.

Can ultra-class mining tyres be processed on-site?

Yes with specialized equipment. Options: Hydraulic shear/cutting system (£120,000-£250,000, cuts into quarters in 15-30 minutes per tyre), mobile cutting rig (£80,000-£150,000, transported to tyre location), cutting torch method (£5,000-£15,000 equipment, 45-90 minutes per tyre, labour intensive). On-site cutting reduces transport costs 60-75% and enables local reuse. Payback: 2-6 years depending on annual volumes and distance to off-site processors.

What can cut mining tyres be used for?

Erosion control on slopes (10-15 sections per 100m slope, £100-£200 saving per tyre vs disposal), drainage layers in haul roads (1 tyre per 2-3 square metres, reduces road maintenance £5,000-£15,000/km annually), blast protection barriers around infrastructure (20-40 tyres per 10m section), void fill for road widening or platforms (50-100 tyres per 100 cubic metres). Check regulatory permissions before on-site reuse (some jurisdictions restrict). Typically reuse 20-40% of generated tyres; remainder requires off-site recycling.

Do mining tyres have recovery value?

Steel content: OTR tyres contain 40-50% steel by weight (1,800-2,700kg steel per ultra-class tyre). Clean steel value: £200-£350 per tonne (£360-£945 per ultra-class tyre steel content). Rubber content: Limited commercial value as rubber compound (£30-£80 per tonne vs £80-£200 for car tyre rubber due to contamination and processing difficulty). Net recovery value offsets 20-40% of disposal costs but doesn’t eliminate expense.

What equipment is needed to cut ultra-class tyres?

Hydraulic shear: 200-300 tonne cutting force, articulated positioning arm, £120,000-£250,000. Mobile cutting system: Self-contained unit transported to tyre, £80,000-£150,000. Cutting torch setup: Oxy-acetylene or plasma cutting equipment, £5,000-£15,000 (labour intensive, 45-90 minutes per tyre). Standard sidewall cutters: Only suitable for tyres under 3,000kg, not ultra-class. For smaller OTR (rigid dump trucks, loaders): Heavy-duty sidewall cutter £25,000-£45,000.

How much space is required for tyre stockpiling?

Whole tyres: Ultra-class tyres occupy 8-12 square metres of floor space each (stacked 1-2 high maximum). 50 tyres require 400-600 square metres. Cut tyres (quartered): Each quarter occupies 2-3 square metres, stackable 3-4 high. 50 tyres (200 quarters) require 150-200 square metres (60-70% space saving). Fire safety: 10-20 metre separation from buildings, 6-10 metre separation between piles. Include fire breaks in space calculations: Add 30-50% to calculated area.

Are there grants or funding for mine tyre processing equipment?

Some jurisdictions offer waste minimization grants or circular economy funding. UK: Check WRAP (Waste & Resources Action Programme), Scotland: Zero Waste Scotland grants (40-70% funding for eligible projects). Australia: State-level environment departments sometimes fund resource recovery infrastructure. South Africa: Department of Environmental Affairs occasionally funds waste minimization projects. Most programs require demonstrating environmental benefit, job creation, or circular economy contribution. Equipment must be permanent installation (not easily relocated).

Conclusion

Mining sites generate 150-300 tonnes OTR tyres plus 6-10 tonnes light fleet tyres annually (typical 200-truck surface operation). Off-site disposal costs £80,000-£100,000 annually including transport (£45,000-£60,000) and tipping fees (£35,000-£40,000).

On-site processing reduces costs 20-31% through quartering (75% volume reduction), on-site reuse (erosion control, drainage, blast barriers), and reduced transport frequency. Equipment investment (£80,000-£250,000) pays back within 2-7 years depending on annual volumes and location.

Regulatory compliance requires waste management plans (mining permit conditions), environmental permits (if storing over 40 tonnes), duty of care (licensed carriers/processors only), and potentially approvals for on-site reuse programs.

For mines generating 100+ OTR tyres annually or located over 200km from processors, on-site processing economics are compelling. Smaller operations or mines near processors continue with off-site disposal supplemented by opportunistic on-site reuse where viable.
