Tyre Baling Equipment for South African Processors: What to Specify

By:     Conor Murphy

The South African Tyre Baling Opportunity

South Africa generates millions of used tyres annually from its vehicle fleet, its substantial transport and logistics sector, and its mining operations. The majority of these tyres require processing through legitimate recycling routes, yet South Africa’s tyre recycling infrastructure, while growing, has not yet achieved the processing capacity and geographic coverage to handle the full volume efficiently.

This gap between tyre generation and processing capacity represents both a waste management problem and a commercial opportunity. Tyre recyclers investing in processing equipment in South Africa are entering a market where the supply of used tyres is consistent and substantial, where regulatory pressure to manage tyres through legitimate routes is increasing, and where the downstream markets for processed tyre products are developing alongside the South African government’s infrastructure investment programme.

Tyre baling for civil engineering applications is one of the most commercially accessible entry points into tyre recycling. The capital cost of baling equipment is substantially lower than that of a crumb rubber shredding line. The operating cost per tyre processed is lower than shredding. And the output, civil engineering bales, serves a market that South Africa’s significant infrastructure investment creates genuine demand for, even in the absence of a formal national tyre bale standard.

Gradeall International manufactures the MKII tyre baler and the broader tyre recycling equipment range from its Dungannon, Northern Ireland, facility. With nearly 40 years of manufacturing experience and equipment in over 100 countries, including significant deployment across sub-Saharan Africa, Gradeall’s team helps South African tyre recyclers specify equipment correctly for their specific operational context.

Understanding the South African Tyre Stream

Before specifying baling equipment, a South African tyre recycler needs to understand the composition of the tyre stream they will be processing. South Africa’s used tyre stream differs from the UK stream in several ways that affect equipment specification.

Tyre age and condition profile. South Africa’s vehicle fleet includes a significant proportion of older vehicles, and tyre replacement is often deferred longer than in higher-income markets. The result is that used tyres entering the South African recycling stream include a higher proportion of heavily worn, cracked, and structurally aged tyres than a typical UK stream. These tyres are suitable for civil engineering purposes but may not be suitable for part-worn resale. The sorting task at intake is to identify any retreading candidates and route them appropriately, then direct the balance to baling or shredding based on their condition.

Tyre size distribution. South Africa’s vehicle fleet includes a significant proportion of smaller vehicles by European standards (entry-level hatchbacks and small sedans are common in urban markets) as well as the larger SUVs and bakkies (pick-up trucks) that are popular across South African consumer and commercial markets. The tyre size distribution across this fleet is broadly compatible with standard PAS 108 baling, which is specified for passenger car and light van tyres.

Imported used tyres. South Africa imports significant quantities of used tyres from other markets, primarily for the part-worn resale market. Some of these imported tyres, those that don’t meet part-worn resale criteria after import inspection, enter the recycling stream. The condition and size profile of imported used tyres varies with the source market; tyres from Asian markets may have different size distributions from European imports.

Commercial vehicle tyres. South Africa’s substantial road freight sector generates significant quantities of used truck tyres. Truck tyres require different processing approaches from car tyres; sidewall cutting with the truck tyre sidewall cutter prepares truck tyres for shredding, and a separate truck tyre baling configuration handles truck tyres for civil engineering bale production.

Core Equipment: The MKII Tyre Baler

The MKII tyre baler is the primary production equipment for a South African car tyre baling operation. Its specification matches the requirements of PAS 108, the British Standard that provides the most detailed technical specification available for civil engineering tyre bales, and which South African civil engineers and infrastructure project managers can reference in project-specific engineering specifications.

Production rate. The MKII produces up to six bales per hour, with each bale containing approximately 100 standard passenger car tyres. For a South African operation running a single shift of eight hours, theoretical maximum production approaches 48 bales per shift. Practical throughput in a well-organised operation with good tyre feed management is typically 35 to 45 bales per shift. This production rate is commercially viable for a processor handling several hundred thousand car tyres per year.

Bale specification. The MKII’s chamber geometry is designed to produce bales within PAS 108 dimensional tolerances: approximately 1.55 to 1.6 metres long, 1.2 metres wide, and 0.7 to 0.8 metres high. The hydraulic compaction system achieves the density required by PAS 108. Every bale the MKII produces is within specification if the tyre loading procedure is followed correctly.

Power requirements. The MKII operates on a three-phase electrical supply. South Africa’s standard industrial electrical supply is 380/400V three-phase, compatible with Gradeall equipment. The specific power connection requirements should be confirmed at the specification stage; any necessary electrical supply upgrades at the installation site should be planned before equipment delivery.

Structural specification for South African conditions. Gradeall’s equipment is manufactured to industrial standards appropriate for demanding operating environments. For South African deployment in regions with high ambient temperatures (particularly Limpopo, Mpumalanga, and the Northern Cape), hydraulic fluid specification should be reviewed for compatibility with local ambient temperatures. Gradeall’s technical team provides guidance on hydraulic fluid specification for South African conditions.

Supporting Equipment: What Completes the Baling System

The MKII baler is the production centrepiece, but a complete tyre baling operation requires several supporting equipment items that are as important to throughput and output quality as the baler itself.

Tyre rim separator. Car tyres arriving with steel or alloy wheels attached must have rims removed before baling. The tyre rim separator removes rims efficiently, recovering the wheel as a separate scrap metal stream (steel and alloy wheels have commercial value in South Africa’s active scrap metal market) and delivering a rim-free tyre ready for baling. In a South African context where tyre generators include scrapyards and vehicle dismantlers as well as tyre retailers, the proportion of rim-on tyres in the incoming stream may be higher than in a pure tyre retail collection stream; rim separation capacity must keep pace with baler feed requirements.

Inclined conveyor. Loading tyres into the MKII manually is physically demanding and limits throughput by making the feed rate dependent on operator pace rather than the baler’s mechanical capacity. Gradeall’s inclined tyre baler conveyor automates tyre feed to the baler, maintaining a consistent supply and improving throughput significantly. For a commercial tyre baling operation targeting maximum throughput across a shift, conveyor-assisted loading is essential rather than optional.

Geotextile wrapping station. PAS 108-compliant bales must be wrapped in geotextile fabric before civil engineering use. The wrapping operation is manual and requires a dedicated workspace adjacent to or near the baler output. The geotextile specification (weight, permeability, material type) should be confirmed with the civil engineering project specification for each buyer relationship. Geotextile fabric is available from South African industrial fabric suppliers; confirming local supply and pricing before committing to a production volume is part of the operational setup.

Bale storage area. Finished bales require hardstanding storage awaiting collection or delivery to civil engineering projects. The storage area must be accessible to collection vehicles (flatbed trucks with telehandler capability are the standard collection transport), adequately drained, and sized to accommodate a buffer stock of several days’ production. Bale accumulation during periods between civil engineering project collections should not strain facility storage capacity; sizing the storage area for at least two weeks of production at the expected throughput rate provides an adequate operational buffer.

Specifying for South African Civil Engineering Markets

The commercial viability of tyre baling in South Africa depends on the existence of civil engineering buyers for the bale output. Unlike the UK, where PAS 108 is formally referenced in infrastructure procurement specifications and established civil engineering project markets for bales exist across the country, South Africa’s tyre bale civil engineering market is at an earlier stage of development.

Infrastructure investment context. South Africa’s significant infrastructure investment programme, including road construction and maintenance, provincial and municipal civil engineering projects, and private sector development, creates potential demand for tyre bales in earthworks, drainage systems, embankment fill, and retaining structures. The engineering case for tyre bales is sound and supported by international research; the commercial development task is making South African civil engineers and project managers aware of the option and providing the technical documentation they need to specify it.

Engineering engagement. South African tyre baling operations that want to develop civil engineering bale sales need to engage proactively with geotechnical engineers, civil engineering consultants, and infrastructure project managers. Providing PAS 108 as the technical reference document for bale specification, alongside the engineering literature on tyre bale material properties and performance in relevant applications, gives engineers the technical foundation they need to consider tyre bales on their projects.

Road agency engagement. The South African National Roads Agency (SANRAL) and provincial road agencies are the largest procurers of road infrastructure. Developing a relationship with SANRAL’s technical and materials teams, presenting the case for tyre bale use in road construction applications, and providing technical data from PAS 108 and supporting research could open significant volumes of civil engineering bale demand as SANRAL’s road programme progresses.

Proximity to projects. The economics of tyre bale supply to civil engineering projects are strongly affected by the transport distance between the baling facility and the project site. Establishing a baling facility within a reasonable distance of major civil engineering activity in Gauteng, the Western Cape, KwaZulu-Natal, or the Eastern Cape provides better commercial logistics than a facility in a location remote from active infrastructure projects.

Financial Case for South African Baling Investment

The financial case for tyre baling equipment investment in South Africa follows the same structure as in the UK and Australia: gate fee income from tyre generators, bale sale revenue from civil engineering buyers, and scrap metal income from rim separation, against equipment capital cost, operating cost, and site overhead.

Gate fees in South Africa vary by tyre type and by region. The regulatory pressure to manage tyres through legitimate routes is creating collection market conditions where tyre generators pay for legitimate disposal rather than relying on informal collection. As awareness of legal obligations under NEM: WA increases, the gate fee market for legitimate tyre processors should strengthen.

Bale sale prices in South Africa are emerging as the civil engineering market for tyre bales develops; they are not yet as established as in the UK. Early movers in South African tyre baling who develop strong civil engineering buyer relationships will set the price discovery for this market.

“The South African tyre recycling market is at an exciting stage of development,” says Conor Murphy, Director of Gradeall International. “The regulatory framework is strengthening, the tyre volumes are substantial, and the infrastructure investment creates genuine demand for the outputs of well-run tyre recycling operations. The businesses that invest in quality processing equipment now and build their civil engineering buyer relationships are positioning themselves well for a market that will only become more structured and more valuable over time.”
