Tyre Stewardship Australia has appointed David Fraser as its new chair, succeeding David Spear after nine years in the role during a period of regulatory and industry change in the country’s tyre-recycling sector.

Spear’s departure closes what the organisation described as a challenging yet incredibly important chapter for its efforts to advance circular outcomes for Australia’s end-of-life tyres. TSA, an industry body backed by government and sector participants, oversees the national stewardship scheme and promotes recycling and re-use pathways for waste tyres, an area facing increasing scrutiny under Australia’s environmental and product-stewardship policies.

In a statement, TSA said it “thank[s] him for his unwavering support and dedication to driving circular outcomes for Australia’s end-of-life tyres”.

Fraser, a TSA director since 2023, brings experience in governance and compliance. He joins at a time when Australian states are tightening environmental standards and seeking to reduce landfill through higher recycling targets. TSA said Fraser has “deep understanding of our strategy, our challenges and the opportunities ahead”.

The organisation added: “We look forward to his leadership as TSA enters its next chapter.”

TSA also expressed appreciation to Spear “for your contribution and support of our mission”, and welcomed Fraser, saying it is “excited and ready for what lies ahead”.

Infiniteria, the tyre recycling joint venture backed by Scandinavian Enviro Systems, Antin Infrastructure Partners and Michelin, has named Kajsa Ryttberg-Wallgren as its new chief executive as the company moves into a phase of industrial expansion.

Ryttberg-Wallgren, who has taken up the role on 1 December, succeeds Stefano Madeddu. She most recently served as chief growth officer at Stegra, a Swedish green steel venture. Her earlier career includes senior positions at PIAB, Yara International, Sandvik and Sapa, giving her broad experience in scaling industrial operations internationally.

The appointment signals a shift in leadership priorities at Infiniteria, with an emphasis on what the company describes as “industrial logic and value creation”. Announcing the move, Anand Jagannathan, senior partner at Antin Infrastructure Partners’ NextGen strategy, said: “We are delighted to welcome Kajsa Ryttberg-Wallgren as CEO of Infiniteria. She offers a strong combination of Swedish industrial experience, a track-record in international expansion and strong sustainability credentials, all of which are highly relevant for Infiniteria and the journey ahead of us.”

Enviro is developing a full-scale tyre recycling plant near Uddevalla on Sweden’s west coast, expected to be Infiniteria’s inaugural site. The venture aims to build additional facilities across Europe to process end-of-life tyres using Enviro’s patented pyrolysis technology, which breaks down materials for reuse in industrial applications. The partners say the process will support circular production models and reduce carbon emissions in sectors heavily reliant on fossil-derived inputs.

The expansion plans place Infiniteria among several European initiatives seeking to commercialise advanced recycling technologies as regulators push for higher material recovery rates and lower industrial emissions.

The International Institute of Synthetic Rubber Producers will recognise two long-serving leaders at its annual meeting next year. Dr Elizabeth Delzell will receive the IISRP General Award, while Dr Irina Yurovska will be presented with the organisation’s Technical Award. Both honours will be given on 15 April 2026 at the group’s 66th Annual General Meeting in Houston, Texas.

Dr Delzell is an epidemiologist whose research has shaped global understanding of chemical exposure in industrial settings. She earned degrees from the University of North Carolina at Chapel Hill and Harvard University before holding academic posts at Duke University and the University of Alabama at Birmingham. Over three decades, she published more than 200 papers and led work funded by IISRP and several major companies and agencies.

Her landmark study in the North American synthetic rubber industry identified 1,3-butadiene as a cause of human leukaemia. The finding influenced national and international rules on chemical safety. Her research also linked synthetic rubber work to bladder cancer and helped assess cancer risks from styrene exposure.

Dr Yurovska, the recipient of the Technical Award, has held leadership roles across the tyre, rubber and chemicals sectors. She trained as a chemist and engineer in the former Soviet Union and later completed a PhD in polymer physics and mechanics. After moving to the United States in 1991, she worked at Teknor Apex, Precix, Cabot Corporation, SI Group and Himadri, rising to Global Vice President of Technical Service.

She holds more than 80 patents and has published widely on polymer compounding, rubber additives and testing methods. Her work has informed advances in rubber technology used across the global industry. She now runs YIGlobal, a consulting company based in Texas, and remains active in the ACS Rubber Division.

The IISRP said both award recipients have made long-lasting contributions to science and the synthetic rubber industry. The organisation highlighted their influence on regulation, product development and talent mentoring across several decades.

Nokian Tyres has named Formula 1 legend Kimi Räikkönen as its newest brand ambassador. This strategic partnership unites two Finnish powerhouses celebrated for excelling under extreme pressure.

In his role, he will actively promote Nokian Tyres' capabilities to a worldwide audience, helping to convey their expertise in mastering the most demanding driving conditions on the planet.

Räikkönen said, “Perfect match, great to start working with Nokian Tyres, a brand I remember from the days when my parents drove me to karting tracks, before I even had a driver's license. In my opinion Nokian Tyres is an iconic Finnish brand, I'm excited to start spreading the good news about the great tyres to the world.”

Tiina Frazer, VP for Brand, Marketing and Communications at Nokian Tyres, said, “Some collaborations just make sense, and this is one of them.

Both are built for extremes – whether it’s conquering the racetrack or navigating roads in changing conditions and harsh weather.”
