In a notable stride towards sustainable tyre manufacturing, Nokian Tyres has introduced the Betula concept tyre, which incorporates a pioneering compound derived from birch bark. This renewable substance is produced by the Swedish firm Reselo, which transforms residual matter from the global pulp, paper and plywood sectors into a viable tyre ingredient. For the first time, this birch-based material has been integrated into a tyre's tread compound, contributing to a tread where recycled and renewable resources now constitute 93 percent of all materials used.

This innovation is viewed as a way to enhance tyre performance. The Betula concept, which utilises the tread pattern of Nokian's Hakkapeliitta R5 winter tyre, has undergone successful testing at the company’s facilities in Ivalo, Finnish Lapland, and in Nokia, Finland. The project marks meaningful progress towards Nokian Tyres’ target of having 50 percent recycled and renewable materials in its tyres by 2030, aiming to establish new environmental standards for the industry through such pioneering efforts.

The collaboration with Reselo originated in 2023 when the biomaterials company won Nokian Tyres’ sustainable innovation challenge. A formal development agreement followed in 2024 to refine the renewable material for tyre applications, and joint development continues even after the concept tyre’s launch.

Concept tyres like the Betula are vital to Nokian’s development process, allowing new materials and technologies to be evaluated before commercial release. This approach has yielded several advanced prototypes, including the 2022 Green Step concept, which also achieved 93 percent renewable or recycled content, and the 2024 Green Step Ligna, featuring a renewable lignin-based alternative to carbon black. The company’s commitment is already reflected in production models, exemplified by the 2025 Nokian Seasonproof 2 all-season tyre for Central Europe, which contains up to 38 percent recycled and renewable materials – the highest proportion in the company’s current commercial lineup.

Teemu Soini, Vice President – Innovations & Development, Nokian Tyres, said, “Since the early stages, the potential of the material to be used in tyres has been evident. The Nokian Tyres Betula concept tyre confirms its applicability and highlights the material’s potential for commercial use in the future. Furthermore, the material is not only sustainable, but according to our testing, it also shows promise to improve tyre performance.”

Josefin Larsson, CEO, Reselo, said, “For Reselo, this partnership represents much more than a technical development project. The tyre industry’s sheer scale and traditionally conservative approach make it a challenging but vital space for rubber innovation, and seeing the collaboration with Nokian Tyres continue to the next level is something we’re especially proud of. Birch bark is a high-volume forestry side-stream abundant in the Nordics, and step by step, we are working together towards better-performing and more sustainable products with circularity at the core.”

Dow Inc. said its chief executive Jim Fitterling will become executive chair of the board from 1 July , 2026, with chief operating officer Karen S Carter appointed as chief executive.

Carter will also join the board on the same date, while Richard Davis will continue as independent lead director.

The company said the changes follow a multi-year succession planning process and are intended to ensure continuity as it advances its strategy as a materials science group.

“On behalf of the Board, I want to thank Jim for his exceptional leadership and continued contributions to Dow,” Davis said. “Jim has led the company through a period of significant transformation while strengthening Dow's strategy, culture and long-term positioning. We are equally pleased to congratulate Karen on her appointment as CEO. She is a disciplined, highly respected leader with a deep understanding of Dow's businesses and customers. This appointment reflects our confidence in her ability to lead Dow forward into its next chapter of growth and value creation for customers, employees and shareholders.”

Fitterling, who has been chief executive since 2018 and chair since 2020, oversaw the company’s separation from DowDuPont and led its repositioning towards higher-growth, consumer-led markets. He also guided the group through broader macroeconomic and geopolitical challenges, while advancing its sustainability ambitions and corporate culture.

“Serving as CEO of Dow has been the privilege of a lifetime,” Fitterling said. “Together with our employees and leadership team, we have transformed Dow into a stronger, more focused company with the right strategy, capabilities and culture for the future. I look forward to continuing to support Dow as Executive Chair and working closely with Karen to help ensure continuity and strong execution.”

As executive chair, Fitterling will continue to lead the board, focusing on long-term strategy, governance and external relationships.

Carter, who has spent more than three decades at Dow, currently oversees business and operational performance across the company as chief operating officer. She previously led the packaging and specialty plastics division, the group’s largest operating segment, where she focused on capacity expansion, asset upgrades and operational reliability, alongside efforts linked to circular economy initiatives.

“I am deeply honored to assume the role of CEO and lead Dow into our next chapter,” Carter said. “Dow has extraordinary people, world-class assets and leading positions in the markets we serve. Our focus remains unwavering: delivering reliable and innovative solutions for our customers, and long-term value for our employees and our shareholders, while accelerating our transformation to set a new competitive standard for best-in-class performance. I look forward to continuing my partnership with Jim in his new role as Executive Chair, and to working with the Board and all of Team Dow to advance our strategy and deliver on our priorities.”
