The U.S. Tire Manufacturers Association (USTMA) has released its 16th End-of-Life Tire Management Report, revealing positive momentum in tyre recycling with 79 percent of end-of-life tyres being consumed by end-use markets.

This reflects a 10.5 percent increase in overall utilisation, reinforcing that end-of-life tyres remain one of the most recycled and reclaimed consumer products, outpacing materials like metal, glass, aluminium, plastic, and paper.

While this progress is encouraging, USTMA emphasises that collaborative efforts across the tyre recycling value chain must continue to fully eliminate illegal and abandoned tyre stockpiles and create sustainable, circular markets for end-of-life tyres (ELT).

Anne Forristall Luke, President and CEO, USTMA, said, “This over 95 percent reduction in stockpiles is the result of decades of progress developing the tyre recycling industry, remediating stockpile sites, and driving innovation.”

“USTMA’s primary goal is to recycle 100 percent of end-of-life tyres into circular, sustainable markets. However, significant work remains, and to achieve full circularity, we must continue to collaborate with manufacturers, recyclers, policymakers, NGOs, and environmental groups to develop and expand the markets for tyre recycling and reclaiming.”

It is interesting to note that that ground rubber has become the second largest market for end-of-life tyres, increasing 29 percent since 2019 and consuming about 28 percent of end-of-life tyres in 2023. Ground rubber is used in a range of applications, including rubberised asphalt for roads, reflecting the growing demand for sustainable materials in infrastructure and everyday products.

Rubber Modified Asphalt (RMA), a key use of ground rubber, is showing significant growth as a cost-effective, durable solution for U.S. infrastructure. Since 2021, RMA has consumed 165,000 tonnes of ELTs, representing a 17 percent increase.

USTMA states it continues to advocate for federal funding to further scale RMA as part of infrastructure development projects, ensuring long-term benefits, performance, environmental impacts, and to advance tyre circularity.

But in contrast, despite the significant achievements made, approximately 48 million end-of-life tyres still remain in stockpiles. USTMA is engaging all stakeholders in the value chain to drive sustainable practices and eliminate these stockpiles. The Tire Recycling Foundation (TRF), a joint initiative of USTMA and the Tire Industry Association, aims to provide critical support by educating, networking, and collaborating with key players in the recycling ecosystem.

“We’ve made considerable progress, but we’re not done yet,” added Luke. “The industry, policymakers, and recyclers must continue to push forward, advocate for market expansion, and invest in sustainable recycling technologies that can help drive a future where 100 percent of tyres are recycled and reclaimed into sustainable, circular end-use markets.”

Future focus areas

In light of the findings from the report, USTMA and its partners state that they will continue to focus on four key growth areas:

Driving Market Growth Through Research and Data

Building on the 2021 Rubber Modified Asphalt State of Knowledge Report, USTMA will release a Tire Derived Aggregate (TDA) State of Knowledge Report later this year, offering data-driven insights to support market growth and innovation. 

Collaborative Engagement Across the Value Chain

USTMA will continue to strengthen partnerships and collaboration among all stakeholders—manufacturers, recyclers, government agencies, and environmental groups—through initiatives like the Tire Recycling Conference and a series of Rubber Modified Asphalt (RMA) workshops, fostering knowledge sharing and advancing tyre recycling solutions across industries.

Leveraging Federal Infrastructure Funding for ELT Markets

USTMA aims to maximise opportunities from the Bipartisan Infrastructure Law (BIL) to scale TDA and RMA markets, reinforcing the critical role of end-use tyres in sustainable U.S. infrastructure.

Supporting Strong State ELT Management Programs

USTMA continues to advocate for robust state programs that effectively manage end-of-life tyres and support sustainable recycling practices, driving innovation and addressing tire stockpile reduction.

Japanese chemical manufacturer Tosoh Corporation announced plans on Wednesday to construct a second chloroprene rubber production facility at its Nanyo Complex, representing an investment of approximately ¥75 billion (£460 million) to meet rising global demand for the speciality polymer.

The new facility, scheduled to begin construction in spring 2027, will add 22,000 metric tonnes of annual production capacity for Tosoh’s SKYPRENE chloroprene rubber brand. Commercial operations are expected to commence in spring 2030 at the Shunan City site in Yamaguchi Prefecture.

Chloroprene rubber serves as a critical component across multiple industries, from automotive manufacturing to medical applications. The synthetic rubber’s popularity stems from its exceptional resistance to oil, weather conditions, and flame exposure, making it suitable for demanding applications, including automotive hoses, industrial belts, adhesives, and medical gloves.

The expansion comes as global demand for high-performance polymers continues to grow, driven by increasing automotive production and stricter safety requirements across industrial sectors. Medical applications have also seen increased demand following heightened awareness of the requirements for protective equipment.

Tosoh’s decision to double down on chloroprene rubber production reflects the material’s position within what the company terms its “Chemical Chain Business” - a strategy focused on value-added speciality chemicals rather than commodity products.

The investment represents one of the larger capacity expansion projects announced by Japanese chemical companies this year, signalling confidence in long-term demand fundamentals despite current global economic uncertainties.

The Nanyo Complex already houses Tosoh’s existing chloroprene rubber operations alongside other chemical production facilities. The site’s established infrastructure and logistics capabilities influenced the decision to expand at the existing location rather than develop a greenfield facility.

Industry analysts note that the three-year construction timeline reflects the technical complexity of chloroprene rubber production, which requires specialised equipment and stringent safety protocols due to the chemical processes involved.

The expansion aligns with broader trends in the Japanese chemical industry, where companies are increasingly focusing on high-margin speciality products to offset competitive pressures in traditional commodity chemicals from lower-cost Asian producers.

Epsilon Carbon, a leading global manufacturer of carbon black, has launched N134, which it claims is a specialised ‘Hard Grade’ carbon black known for its superior abrasion resistance and durability.

At present, the high-quality N134 grade is being imported due to the lack of consistent quality and supply chain issues in the Indian market. As a result, the tyre makers have to modify their formulations using other grades of carbon black, which it shared often leads to reduced performance.

But now, Epsilon Carbon has become the first company in India to install a dedicated manufacturing unit designed for N134 grade hard carbon. The company is expanding its existing Vijayanagar Carbon complex facility to produce 215,000 tonnes of carbon black.

This will not only ensure consistent supply of N134 carbon black for tyre makers in the country, reduce import dependency, but also open up export potential to markets such as Europe and USA. Epsilon Carbon will also focus on integrate advanced processing techniques to ensure batch consistency for durability and performance.

Vikram Handa, Managing Director, Epsilon Carbon, said, “This is a proud moment for us and for India’s carbon black manufacturing sector as the high quality N134 black will significantly reduce import dependency and provide tire manufacturers in India and abroad with a reliable, high-quality product. Our goal is to match global standards while building India’s capability to serve premium markets.”

Lummus Technology, a leading provider of process technologies and energy solutions, has signed a memorandum of understanding (MoU) with InnoVent Renewables to collaborate on the global licensing and deployment of InnoVent’s continuous tyre pyrolysis technology.

Under the proposed agreement, Lummus will become the exclusive licensor for InnoVent’s proprietary pyrolysis process, which transforms end-of-life tyres into valuable outputs, including pyrolysis oil, gas, recycled carbon black and steel. Additionally, Lummus will offer integrated technology packages that combine InnoVent’s pyrolysis system with its own downstream processing solutions, enhancing the value of fuel and chemical products derived from waste tyres.

InnoVent’s technology provides a fully scalable, end-to-end solution for converting discarded tyres into renewable fuels and high-value petrochemicals, covering everything from pre-processing to purification. The company currently operates a commercial-scale facility in Monterrey, Mexico, with an annual processing capacity of up to one million passenger tyres, and has the capability to expand further.

Leon de Bruyn, President and Chief Executive Officer, Lummus Technology, said, “This is another significant step in expanding and strengthening our portfolio for the circular economy. By combining InnoVent’s tyre recycling technology with Lummus’ global licensing and engineering expertise, we will be addressing the global challenge of waste tyres and creating new pathways for sustainable product development.”

Vibhu Sharma, Chief Executive Officer, InnoVent Renewables, said, “Partnering with Lummus has the potential to accelerate the global deployment of our technology and help us address the environmental and public health challenges of one billion end-of-life tyres that are disposed of annually. Together, we can transform waste into valuable resources, reduce carbon emissions and support the transition to a more sustainable future.”

Continental is accelerating its efforts to make tyre production more sustainable, with the German tyre manufacturer expecting the share of renewable and recycled materials in its tyres to rise by up to three percentage points in 2025.

The average share stood at 26 percent in 2024, and Continental said it anticipates a further increase this year due to the expanded use of materials such as synthetic rubber derived from renewable sources, recycled PET polyester, recycled steel, and silica made from rice husk ash — a by-product of rice production.

“We are systematically increasing the share of renewable and recycled materials in our raw material portfolio. In five years, we aim to surpass the 40 percent mark,” said Jorge Almeida, Head of Sustainability at Continental Tires. “To achieve sustainable mobility, we are constantly searching for even more environmentally friendly materials. After extensive testing, we integrate them into production as quickly as possible.”

The company has set a goal of using over 40 percent renewable or recycled materials in its tyres by 2030, without compromising on performance or safety.

A key pillar of this transformation is the adoption of mass balance-certified materials. This approach, certified under ISCC Plus, enables Continental to mix certified and non-certified materials during production while maintaining strict accounting procedures to ensure traceability.

The company has already secured ISCC sustainability certification for its tyre plants in Lousado (Portugal), Hefei (China), Púchov (Slovakia) and Korbach (Germany). Continental is also scaling up its use of recycled steel, silica from rice husk ash, and PET yarns made from recycled plastic bottles via its proprietary ContiRe.Tex process.

Other sustainable innovations include COKOON, an adhesive coating system co-developed with Kordsa that replaces formaldehyde and resorcinol in bonding textile components with rubber. Continental also continues to explore alternative additives derived from renewable sources to improve the tyre vulcanisation process.

“We have developed a comprehensive portfolio of diverse, more sustainable materials and are continuously integrating them into all our products after extensive testing,” Almeida said. “In doing so, we ensure that there is no compromise in safety or performance. With this portfolio, we are getting closer and closer to our ambitious, long-term sustainability goals.”
