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.”

Japan’s Zeon Corp has established a new research facility at its Zeon Chemicals Yonezawa site to develop plant-based production processes for synthetic rubber raw materials as it accelerates efforts to decarbonise its operations and support a circular economy.

The new lab will focus on advancing biofermentation and chemical reaction technologies to produce butadiene and isoprene—key building blocks for synthetic rubber—directly from plant-derived feedstocks.

“This facility will accelerate the development of biotechnology to produce butadiene and isoprene directly... to contribute to the realisation of a circular economy,” the Tokyo-based company said.

The initiative is part of Zeon’s “STAGE30” medium-term business plan, which includes a target to cut group-wide carbon dioxide emissions by 42 percent by fiscal 2030 from 2020 levels. The company has made “Promoting a transformation of monozukuri to realise carbon neutrality and a circular economy” its top strategic priority under the plan.

The research centre, completed on 23 May, spans 590.34 square metres and features laboratories with local exhaust ventilation alongside office and meeting spaces. Yamagata Prefecture partially funded it under its Business Location Promotion Subsidy Programme.

The project is also supported by Japan’s Green Innovation Fund, run by the New Energy and Industrial Technology Development Organization (NEDO), which backs long-term industrial decarbonisation initiatives. Zeon is collaborating with Yokohama Rubber Co and several academic institutions on two key development themes, including the use of plant-based and sustainable materials for producing rubber intermediates.

Zeon said it aims to commercialise the technology for producing butadiene and isoprene from plant sources by 2034.
