Waste transfer stations receive end-of-life tyres from a wide range of sources: local authority collection rounds, tyre dealers, vehicle workshops, skip hire operators, and direct public drop-off. The result is a mixed stream of car tyres, van tyres, truck tyres, and occasionally agricultural or OTR types, arriving at irregular intervals throughout the week.

Loose tyres present a set of well-known problems. They take up a disproportionate amount of floor and yard space relative to their weight. They’re resistant to compaction without dedicated equipment. They create a significant fire risk when stockpiled in volume. They’re expensive to move and to transport loose to downstream processing facilities. And they attract regulatory scrutiny under environmental permit conditions that specify how tyres must be stored and managed on a permitted site.

Tyre baling addresses all of these problems. It reduces tyre volume by up to 80 per cent, transforms a loose stockpile into stable, stackable bales that can be handled by a standard forklift, and creates a product that can be transported in a standard shipping container at a fraction of the cost of loose tyre haulage.

This guide is aimed at waste transfer station operators considering baling equipment, or those already operating a baler who want to get more from the process.

How Baling Changes the Economics of Tyre Management

The economic case for tyre baling at a waste transfer station rests on three factors: reduced storage footprint, lower transport costs, and access to better downstream markets.

Storage footprint: A loose tyre takes up roughly 0.12 to 0.15 cubic metres of space when stacked. A PAS 108-compliant bale containing 80 to 100 car tyres occupies approximately 1.0 to 1.2 cubic metres. That’s a volume reduction of 80 to 85 per cent per tyre. For a transfer station receiving 500 car tyres per week, the difference between storing them loose and storing them as bales is the difference between filling a large storage bay and filling a corner of it.

Transport costs: Loose tyres are bulky and awkward to load. Transporting them to a processing facility or energy recovery plant in a tipping vehicle or flatbed wastes a substantial proportion of the payload on air. Baled tyres load efficiently into a standard 20-foot or 40-foot container, allowing operators to maximise transport loads and reduce the number of vehicles required for the same tonnage.

Market access: PAS 108-compliant tyre bales have value as a material in civil engineering and construction applications. Tyre bales that meet the standard can be supplied for use in land drainage, embankment construction, slope stabilisation, and retaining wall projects. This opens a commercial route that does not exist for loose tyres, and changes the tyre stream from a disposal cost to a material that may generate revenue or at least reduce haulage costs through supplied-rather-than-transported movement.

Equipment Selection for Transfer Station Operations

Waste transfer stations typically have different requirements from dedicated tyre recycling operations. The tyre stream is mixed in type, volumes fluctuate, and space is often shared with other waste streams and operations.

The MKII Tyre Baler is the standard choice for mid-to-high volume transfer station applications. It handles car and light van tyres effectively in a single-operator process and produces PAS 108-compliant bales at up to 6 per hour. Its robust construction suits the demanding environment of a transfer station where the equipment needs to perform reliably with varying tyre types and occasional abuse from loading.

For smaller transfer stations with lower tyre volumes (under 100 car tyres per day), the MK3 Tyre Baler offers a more compact and lower-capital option while still producing compliant bales.

For transfer stations that also receive truck tyres in significant volumes, a truck tyre sidewall cutter alongside the baler is worth considering. Truck tyres bale at a much lower density without pre-processing, and the sidewall cut significantly improves the quality and consistency of the resulting bale.

For sites receiving OTR or agricultural tyres, additional pre-processing equipment is required before baling. See the full tyre recycling equipment category for the range of processing options.

Site Layout Considerations for Transfer Stations

Transfer stations present specific layout challenges for tyre baling operations. Vehicle movements dominate the site, space is at a premium, and the tyre baling operation needs to integrate with rather than obstruct the wider site workflow.

Separation from vehicle movement: The baling area should be clearly separated from main vehicle movement routes. An operator loading tyres into a baler does not need to be in a zone where tipping vehicles are manoeuvring. This is both a practical efficiency consideration and a health and safety requirement.

Input tyre storage: Transfer stations often receive tyres in batches as vehicles arrive. The baling operation may not be able to process each delivery immediately, so a temporary holding area adjacent to the baler (but outside the operator’s working zone) allows deliveries to be received and staged without disrupting the baling process.

Bale output and collection: Finished bales need to be collected by forklift and moved to a storage area or loaded onto outbound vehicles. Plan a clear and unobstructed forklift route from the bale ejection point to the bale storage area, without this route crossing the operator’s loading area or the input tyre storage zone.

Conveyor integration: For higher-volume transfer station operations, an inclined tyre baler conveyor removes manual tyre loading from the operator’s role, increasing throughput and reducing physical demand. The conveyor loading point can be positioned to receive tyres directly from a tipping area, creating a flow from delivery through baling to stacked bales without manual handling of individual tyres.

Managing a Mixed Tyre Stream

Transfer stations rarely receive a homogeneous tyre stream. Managing a mix of car tyres, van tyres, truck tyres, and occasional larger types efficiently requires a process for sorting and routing different tyre types.

For sites processing primarily car and light commercial tyres, sorting is not complex: most tyres go straight to the baler. The main sorting decision is rim-on versus rim-off. Tyres arriving with rims still attached need rim removal before baling. A tyre rim separator handles this quickly and cleanly. Attempting to bale rimmed tyres damages the baling chamber and produces non-compliant bales.

For sites with a significant truck tyre volume, a sorting step to separate car and truck tyres before processing allows each stream to be handled optimally. Car tyres go directly to the baler. Truck tyres go through the sidewall cutter before baling, or are batched separately if a dedicated truck tyre baler is used.

For sites that receive all tyre types, including agricultural and OTR, a more structured triage process at the intake point routes each tyre type to the appropriate processing path. Large OTR tyres that require splitting before any further processing should be identified at intake and held until the appropriate equipment is available, rather than being mixed into the general tyre processing flow.

Environmental Permit Compliance for Tyre Storage

Transfer stations operating under an environmental permit face specific requirements for tyre storage and management. These requirements vary by permit type and regulatory authority, but common themes include:

  • Limits on the quantity of tyres that can be stored on site at any time
  • Requirements for fire risk management, including separation distances between tyre stockpiles and buildings or other materials
  • Requirements for tyre stockpiles to be covered or otherwise protected from weather conditions that could create runoff
  • Record-keeping requirements for tyre receipts and outgoing movements

Tyre baling directly supports compliance with several of these requirements. Baling reduces the volume of tyres on site, helping sites stay within permitted storage quantities at higher throughput levels. Baled tyres present a reduced fire risk compared to loose stockpiles (the compressed density reduces air circulation within the bale, limiting fire spread), a factor that Environmental Agency inspections increasingly consider.

The Environment Agency’s guidance on waste management and tyre storage sets out the applicable requirements for England. Similar guidance applies in Scotland (SEPA), Wales (Natural Resources Wales), and Northern Ireland (NIEA). Operators should confirm their specific permit conditions with their regulator.

Tyre Bales as an Output Product

For transfer stations that achieve PAS 108 compliance in their baling process, the finished bale is a product rather than a waste material. This distinction matters both commercially and for regulatory purposes.

PAS 108 is the British standard for tyre bales used in civil engineering and construction. A bale produced to this standard has defined dimensions, mass, density, and tie specifications, and can be supplied for civil engineering applications, including land drainage, embankment construction, and slope stabilisation.

The pathway to PAS 108 compliance requires consistent process control: correct tyre type per bale, correct loading quantity, sufficient compression force, correct number and positioning of ties, and dimensional verification. The MKII Tyre Baler is designed to produce bales to PAS 108 specification when operated correctly.

Transfer stations interested in producing PAS 108-compliant bales should establish a documented baling procedure, train operators on the specification requirements, and implement a bale sampling and measurement regime to confirm compliance on an ongoing basis. Gradeall can provide guidance on the process requirements alongside the equipment.

Frequently Asked Questions about Tyre Baling at Waste Transfer Stations

Tyre baling raises practical questions for transfer station operators at every stage, from equipment selection to permit compliance. The answers below cover the issues that come up most often.

How many tyres does a transfer station need to receive to justify a baler?

The threshold varies by operational context, but as a rough guide, a transfer station receiving 200 or more car tyres per week can typically justify a tyre baler on the basis of reduced transport costs and storage space savings alone. Sites at lower volumes may find a contract processing arrangement more cost-effective than owning and operating their own equipment.

Can I bale tyres and other waste materials in the same baler?

Not in a tyre baler. Tyre balers are specifically designed for tyre geometry and loading characteristics. If you also need to bale cardboard, plastic, or general waste, these require separate equipment. Gradeall manufactures a wide range of balers for different waste streams; see the vertical balers and compactor ranges for other waste management equipment.

What do I do with tyres that can’t be baled directly, such as very large OTR tyres?

OTR tyres require pre-processing before baling. An OTR tyre splitter reduces these tyres to a size suitable for further processing. For transfer stations receiving only occasional OTR tyres, it may be more practical to arrange separate disposal for these than to invest in the pre-processing equipment.

How are bales transported from the transfer station to the end user?

Standard flatbed vehicles or shipping containers. PAS 108 bales are stable and can be stacked in containers. For civil engineering applications, the bales are typically collected by the project contractor directly. For energy recovery destinations, collections are arranged through the processing facility.

Does baling change how tyres are classified under waste regulations?

The regulatory classification of waste tyres and tyre bales depends on the specific regulatory context and end use. PAS 108-compliant bales supplied for civil engineering applications may qualify for end-of-waste status, but this requires specific assessment. Consult with the relevant regulatory authority or your waste management advisor regarding the classification applicable to your specific situation and location.
