The German Rubber Industry Association (wdk) has sounded an alarm over an exceptionally difficult economic situation facing the rubber sector. Soaring raw material prices and persistently high energy costs, exacerbated by the Iran war, are coinciding with weak industrial demand. wdk Chief economist Michael Berthel noted an almost unprecedented economic disparity, as raw material costs approach historical highs from 2011 and 2022 while a lack of demand prevents any offset for manufacturers.

Since the final quarter of 2025, prices for key inputs have risen sharply. Natural rubber has jumped more than 40 percent within months, while butadiene-based synthetic rubbers have increased over 30 percent. EPDM synthetic rubber, carbon black and oil-based plasticisers have all risen more than 20 percent, with some individual chemicals exceeding 40 percent cost growth in just a few weeks.

Energy prices remain a major burden, with Middle East developments fuelling market uncertainty. Risks to international transport and supply chains persist, and German rubber companies are closely watching potential impacts on raw material availability and global logistics flows.

Berthel warned that firms face mounting pressure from high costs, geopolitical instability and structural disadvantages in Germany, with no short-term relief in sight. The industry depends heavily on fair and reliable partnerships across the value chain, as processing companies alone cannot absorb the current strain. He called for fair solutions and a shared understanding of this exceptional situation.

As Extended Producer Responsibility (EPR) frameworks expand globally, the tyre industry is undergoing a structural transformation. Collection systems are improving, traceability is increasing and investments in recycling technologies are accelerating. However, one critical tension remains insufficiently addressed: the speed of industry evolution is outpacing the agility of public policy. And within that gap, one key question emerges: where does retreading fit in this new circular economy architecture?

A STRUCTURAL PARADOX

Retreading represents one of the most efficient forms of resource optimisation in the tyre lifecycle. It extends product life, reduces raw material consumption and lowers emissions. Yet, in many regulatory frameworks, it is still treated ambiguously – often grouped with recycling rather than recognised as prevention or preparation for reuse. This distinction is not semantic. It is strategic. Because when policy fails to differentiate, markets fail to prioritise.

A FAST-MOVING INDUSTRY, A SLOW-MOVING FRAMEWORK

The tyre market is evolving in real time:

1. Increasing penetration of low-cost imports.
2. Growing variability in product quality.
3. Accelerated turnover cycles.

Retreading, in this context, becomes more than a circular solution. It becomes a filter of industrial quality. Not all tyres are equally retreadable. And that difference defines their real contribution to circularity. Yet most EPR systems continue to operate with uniform economic signals, failing to distinguish between products that enable multiple lifecycles and those that exit the system after a single use.

SIGNALS FROM EUROPE

Recent developments in countries like Portugal – where eco-fees applied to retreaded tyres approach those of low-cost, non-differentiated new tyres – highlight a concerning trend. Similarly, in Spain, industry representatives continue to advocate for a clearer institutional recognition of retreading within EPR systems. These cases illustrate a broader issue: circular policies can unintentionally undermine higher-value circular strategies.

THE MISSING LINK: PERFORMANCE-BASED POLICY

What is missing is not regulation. It is regulatory precision. EPR systems have successfully organised waste flows. But they have not yet evolved to reward performance within the lifecycle. This is where eco-modulation becomes critical.

ECO-MODULATION AS A STRATEGIC LEVER

Eco-modulation should not be a marginal adjustment. It should be a core industrial policy tool. Properly designed, it can:

• Differentiate tyres based on real circular
• performance.
• Incentivise durability and retreadability.
• Penalise short-lifecycle, non-recoverable products.
• Align market behaviour with system objectives.
• To operationalise this, we need new metrics.

FROM COMPLIANCE TO PERFORMANCE: A PROPOSED FRAMEWORK

The next step for EPR systems is to move towards performance-based differentiation. This could be implemented through instruments such as:

• Retreadability Index (RI)
• Performance Score (CPS)

These would measure:

• Number of effective retreading cycles per tyre.
• Structural durability and casing quality.
• Real contribution to lifecycle extension.

Under such a system:

• Tyres with higher retreadability would receive lower eco-fees.
• Products that systematically fail to re-enter the cycle
• would face higher costs.
• This is not just a technical refinement. It is a shift from:
• Generic compliance.
• To intelligent market shaping.

THE LATIN AMERICAN PERSPECTIVE

In Latin America, the stakes are even higher.

The region faces:

• Structural dependence on imported tyres.
• Strong presence of low-cost, low-durability products.
• Emerging EPR frameworks (Chile, Costa Rica, Peru, Ecuador)

Chile, for example, through its EPR law (Ley REP), has made significant progress in structuring collection and recovery targets. However, like many systems, it still faces the challenge of fully integrating reuse strategies into its economic logic. Under these conditions, retreading is not just an environmental solution. It is a strategic industrial capability.

BEYOND WASTE MANAGEMENT

Latin America has a unique opportunity to design EPR systems not only to manage waste

but to govern resources and shape markets.

This means:

• Incentivising retreadable tyres
• Strengthening local retreading industries
• Reducing dependence on short-lifecycle imports
• Building resilience into supply chains

But this requires something critical: policy agility. Because if regulation lags behind market dynamics, it will not transform the system – it will merely formalise its inefficiencies.

A STRATEGIC CONCLUSION

If EPR systems are designed without properly integrating retreading – and without differentiating based on actual circular performance – they risk reinforcing a linear logic under a circular narrative. For emerging regions, this would be a critical mistake

The discussion around repair, reuse and retreading can no longer be treated merely as a waste management issue. It is increasingly becoming a matter of industrial resilience, strategic autonomy and economic security.

As global supply chains face growing pressure from geopolitical fragmentation, logistics disruptions and volatility in raw material markets, extending the useful life of products is emerging as a strategic capability for nations and industries alike.

In this context, Right to Repair should not be understood only as a consumer right but also as an industrial policy tool capable of strengthening local economies, reducing external dependency, preserving technical capabilities and supporting more resilient production systems.

Retreading, remanufacturing and reuse are part of a broader transition where value creation is no longer based exclusively on extraction and disposal but increasingly on intelligence, efficiency and lifecycle management.

CIRCULARITY WITHOUT HIERARCHY BECOMES INEFFICIENCY. REGULATION WITHOUT DIFFERENTIATION BECOMES DISTORTION.

Final note

The future of the tyre industry will not be defined only by how we recycle, but by how intelligently we extend the life of what we already produce. And that requires alignment between:

• Industry dynamics.
• Policy design.
• And strategic vision.

In that equation, retreading must move from the margins to the centre. Because properly understood, it is not just a process. It is a strategic filter, an industrial policy tool and a geopolitical lever.

The Association of Natural Rubber Producing Countries (ANRPC) has released its market report for May 2026, depicting a sector characterised by sustained price strength and firm fundamentals. The global natural rubber market received additional upward momentum from a decline in Brent crude oil prices, which averaged USD 107.14 per barrel during the month. This represented a month-on-month decrease of 8.65 percent, attributed to easing geopolitical tensions in the Middle East and the temporary reopening of the Strait of Hormuz, which collectively bolstered the commodity's outlook.

Global production projections for 2026 stand at 15.337 million tonnes, marking a 2.4 percent increase from the previous year, with growth driven by Thailand, China, India and Malaysia, even as output moderates in Indonesia and Vietnam. Monthly production, however, fell to 997,000 tonnes in May, a year-on-year decline of 4.7 percent, due to seasonal wintering and dry weather conditions across South and Southeast Asia. Concurrently, worldwide consumption is forecast to rise by 1.3 percent to 15.550 million tonnes for the year, with May's consumption reaching 1.310 million tonnes, a 4.6 percent annual increase. This demand was underpinned by steady tyre manufacturing, electric vehicle-related consumption and resilient purchasing managers' indices in China and India, alongside record auto retail sales in India.

Physical prices for all major grades recorded broad-based gains throughout May, with SMR-20, STR-20, RSS-3, RSS-4 and latex all experiencing increases. Trade flows showed a mixed pattern, as imports from China and India contracted month-on-month, while Malaysia and Vietnam registered significant gains. On the export front, Cambodia, Vietnam and Thailand recorded increases, whereas Indonesia and Malaysia saw declines. Currency movements saw the Malaysian ringgit ease slightly, while the Thai baht traded within a stable range, and both nations reported decelerating GDP growth for the first quarter of 2026. Futures contracts on the SHFE and SGX reflected tightening supply and firm demand, posting notable month-on-month gains.

The market outlook remains cautiously balanced against a backdrop of several macroeconomic factors. Elevated trade tensions between United States and China, ongoing geopolitical conflicts and a steady United States Federal Reserve interest rate policy present potential headwinds. However, these are being offset by supportive elements, including the accelerating adoption of electric vehicles, tight feedstock supply due to adverse weather and the positive market sentiment generated by the European Union's decision to lower anti-dumping duties on Chinese tyres.

A new bio-based cut & chip resin for the most demanding applications.

NaugaShield BIO-TR 30 is SI Group’s latest advancement in bio-based performance resins designed to significantly improve cut and chip resistance in high-severity rubber applications. With approximately 75 percent bio-based content, this innovative material delivers on sustainability targets while exceeding the performance typically associated with petroleum-derived resins, making it a strong choice for applications such as OTR tyres in mining, construction and agriculture, mining conveyor belts, rubber tracks and mill linings.

Cut and chip resistance is a complex set of material behaviours, including static mechanical strength, dynamic response under deformation and ability to withstand sharp impacts and abrasive environments. In demanding applications such as mining or agriculture, materials must tolerate repeated high-strain loading and resist the initiation and propagation of tears. NaugaShield™ BIO-TR 30 was developed precisely to meet these conditions, demonstrating notably low dynamic heat buildup and excellent tear strength – characteristics closely tied to enhanced cut and chip resistance and long-term durability under cyclical loads.

To evaluate its performance, NaugaShield BIO-TR 30 was benchmarked in an Off-road Rib Tread formulation against two widely used industry references: a gum rosin/semi-aromatic C5/C9 resin combination and a styrenated DCPD resin. All materials were tested at an equal loading of 10 phr to provide a direct and unbiased comparison. Under these conditions, the bio-based resin consistently outperformed both alternatives, offering a stronger balance of reinforcing behaviour, improved tear propagation resistance and superior resistance to thermal degradation during dynamic flexing. Further improvements were achievable by reducing the amount of free extender oil in the compound, underscoring the resin’s adaptability in formulation design and its ability to unlock even greater performance when optimised.

These laboratory indicators were corroborated through extended Coesfeld Cut & Chip testing (see chart), in which compounds were subjected to up to 3,000 cycles at 200 rpm under a 200N applied force. Formulations containing NaugaShield BIO-TR 30 exhibited substantially lower mass loss and maintained tread surface integrity more effectively than the hydrocarbon and gum rosin-based-benchmarks. The performance advantage was even more pronounced in compounds adjusted for lower free oil content, confirming that the resin can be tailored to meet the durability requirements of the most challenging operating conditions.

The strong performance of NaugaShield BIO-TR 30 in OTR tread compounds can be readily transferred to other rubber goods that encounter similar wear mechanisms. Applications such as mining belts, agricultural and construction tracks or mill linings benefit from the resin’s ability to reinforce the rubber matrix, reduce crack growth under repeated impact and maintain structural cohesion under high-strain deformation. This versatility allows manufacturers to integrate a 75 percent bio-based resin that supports sustainability by reducing fossil-based content and helping end products last longer while maintaining – and often improving – operational performance across multiple product lines.

NaugaShield BIO-TR 30 is currently available in commercial quantities, enabling compounders and manufacturers to move directly from laboratory evaluation to pilot- and production-scale trials.
