Hankook Tire has achieved a significant milestone in its sustainability journey by successfully commercialising tyres made with ISCC PLUS certified carbon black derived from end-of-life tyres. This achievement is a result of the company’s collaboration with HD Hyundai Oilbank and HD Hyundai OCI within the Tyre-to-Tyre Circular Economy Model consortium.

By incorporating recycled materials into its production process, Hankook is reducing its reliance on fossil fuels and contributing to a more sustainable future. The company’s commitment to sustainability is further evidenced by its recent approval from the Science Based Targets initiative (SBTi) for its ambitious net-zero emissions goals.

Hankook continues to lead the industry in developing innovative and eco-friendly tyre solutions. Through its ongoing research and development efforts and strategic partnerships, the company aims to drive the transition towards a circular economy in the tyre industry.

Bekaert has entered into a strategic cooperation agreement with CITIC Special Steel, a prominent Chinese producer of specialised steel products. The partnership establishes a formal framework for technical collaboration aimed at addressing the viability of reintegrating steel reclaimed from scrap tyres into the production of new tyre reinforcement materials. The core objective is to determine whether end-of-life tyre steel can be effectively processed into wire rod suitable for manufacturing fresh reinforcement components.

The initiative merges CITIC Special Steel’s advanced capabilities in steelmaking and rod production with Bekaert’s specialised knowledge in tire reinforcement technologies. Together, the firms will conduct a technical assessment of material flows to gauge the feasibility of establishing more circular loops within the tyre manufacturing value chain. Their joint efforts will prioritise the examination of closed-loop steel usage on a significant scale.

This proof-of-concept endeavour is in its nascent stages and will concentrate on cooperative technical assessments, industrial-scale trials and exhaustive material analyses. The resulting data will clarify the technical, operational and financial consequences of integrating substantial proportions of circular steel. The programme seeks to ensure that any potential solutions adhere to the rigorous quality and performance benchmarks demanded by the sector while also mapping out future strategic directions.

The official signing ceremony occurred in Jiangyin, China, with delegations from both entities convening to deliberate on innovation and sustainability. As demand for eco-friendly alternatives intensifies across the automotive and materials sectors, this collaboration is designed to expand current knowledge and test technical limits. It represents a continuation of Bekaert’s wider sustainability agenda, which includes solutions like Dramix LoopTM, and reaffirms a mutual dedication to pioneering future industry standards through ecosystem-wide innovation.

Jim Dobson, SVP – Technology & Quality, Bekaert, said, "The transition towards more circular industries requires innovation and close collaboration throughout the value chain. Through this cooperation, we are bringing together complementary expertise to explore the technical feasibility of tyre-to-tyre circularity.”

Jiang Qiao, General Manager Sales Company, CITIC Special Steel, said, "We are pleased to deepen our relationship with Bekaert through this strategic cooperation. Together, we will explore how innovation in steelmaking and materials technology can help advance new approaches to circularity in tyre reinforcement applications."

Michelin and Axens have entered exclusive negotiations on a strategic partnership to accelerate the industrial deployment of 5-Hydroxymethylfurfural (5-HMF), a bio-based chemical developed with IFP Energies Nouvelles (IFPEN) for use in sustainable industrial applications.

Under the proposed agreement, Axens would contribute its licensing and engineering expertise to support the global rollout of the technology, while Michelin, through its ResiCare brand, would continue to develop production capacity. The companies said the partnership is intended to help replace selected fossil-derived chemicals with renewable alternatives sourced from plant materials.

A first production unit, located at Péage-de-Roussillon in France, will be operated by Michelin ResiCare. The facility will have an annual production capacity of about 3,000 tonnes and is expected to begin operations in early 2027.

The technology is the result of a joint research and development programme between Michelin ResiCare and IFP Energies Nouvelles, supported by France's ADEME and the European Union's Circular Bio-based Europe Joint Undertaking (CBE JU).

5-HMF is a bio-based platform molecule used in the manufacture of resins, adhesives and polymers. It can also be used to produce polyethylene furanoate (PEF), a bio-based plastic regarded as an alternative to polyethylene terephthalate (PET), with potential applications in food packaging, bottles and textile fibres. The molecule can also be used in solvents, specialty chemicals and intermediates, while replacing selected petroleum-derived compounds, including formaldehyde, in existing industrial processes.

Jacinthe Frecon, vice-president of Process and Equipment Innovation at Axens, said: “This project fully illustrates Axens’ ambition to turn breakthrough innovations into concrete industrial solutions on a global scale. By combining a technology born from leading research collaborations with IFP Energies Nouvelles with our licensing and engineering know-how, we have the opportunity to accelerate the deployment of key bio-based solutions for the transition to more sustainable chemistry.”

Laurent Lemonnier, chief executive of Michelin ResiCare, added: “We are convinced that 5-HMF is set to become a reference platform molecule for sustainable chemistry. Our planned partnership with Axens is a decisive lever to accelerate its global deployment and meet growing demand for high-performing bio-based solutions. This collaboration confirms the strong development potential of 5-HMF across a wide range of applications, as well as the performance of our technology developed with IFPEN. It fully reflects Michelin ResiCare’s commitment to developing innovative solutions that contribute to a safer, more sustainable world.”

Michelin said its work on alternatives to formaldehyde and resorcinol in adhesive resin formulations began in 2008. Since 2021, the company has collaborated with IFP Energies Nouvelles to develop a production process for 5-HMF based on fructose. The molecule is now used across all new Michelin ResiCare formulations for composites, plywood, abrasives and moulded compounds.

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.
