Goodyear Tire & Rubber Company has unveiled a demonstration tyre comprising 90 percent sustainable materials. This demonstration tyre has passed all applicable regulatory testing as well as Goodyear’s internal testing.

Bringing a 90 percent sustainable-material tyre to market will require further collaboration with the company’s supply base to identify the scale necessary for these innovative materials to produce that specific tyre at high volumes.

Goodyear claims that this demonstration tyre also tested to have lower rolling resistance when compared to the reference tyre made with traditional materials. Lower rolling resistance means the demonstration tyre has the potential to offer better fuel savings and carbon footprint reduction.

The tyre company states that the 90 percent sustainable-material demonstration tyre includes 17 featured ingredients across 12 different components, including –

• Carbon black, which is included in tyres for compound reinforcement and to help increase their life, has traditionally been made by burning various types of petroleum products. The demonstration tyre features four different types of carbon black that are produced from methane, carbon dioxide, plant-based oil and end-of-life tyre pyrolysis oil feedstocks. These carbon black technologies target reduced carbon emissions, circularity and the use of bio-based carbons, while still delivering on performance.

• As per Goodyear, the use of soybean oil in this demonstration tyre helps keep the tyre’s rubber compound pliable in changing temperatures. Soybean oil is a bio-based resource that helps reduce Goodyear’s use of petroleum-based products. The tyre manufacturing company claims that while nearly 100 percent of soy protein is used in food/animal feed applications, a significant surplus of oil is left over and available for use in industrial applications.

• Silica is an ingredient often used in tyres to help improve grip and reduce fuel consumption. According to Goodyear, the demonstration tyre includes a high-quality silica produced from rice husk waste residue (RHA silica), a by-product of rice processing that is often discarded and put into landfills.

• Resins are used to help improve and enhance tyre traction performance. In the demonstration tyre, Goodyear states that traditional petroleum-based resins are replaced with bio-renewable pine tree resins.

• Bead wire and steel cords provide reinforcement in the structure of a radial tyre. The tyre manufacturer claims that the demonstration tyre uses bead wire and steel cord from steel with high recycled content, which is produced using the electric arc furnace (EAF) process. The utilisation of the EAF process allows for steel to be produced with reduced energy use and higher recycled content. The EAF process has the potential for lower greenhouse gas emissions in comparison with steel produced using a blast furnace.

• Goodyear claims that ISCC certified mass balance polymers from bio and bio-circular feedstock are also included in this tyre.

In addition, after announcing the capability to demonstrate a 70 percent sustainable-material tyre in January 2022, Goodyear, working with its supply base, plans to sell a tyre with up to 70 percent sustainable-material content in 2023. With the introduction of a tyre with up to 70 percent sustainable-material content, the company claims that it is demonstrating tangible commitment with in-market solutions to building a better future. The tyre manufacturing company states that consumers interested in purchasing this tyre can register for updates at Goodyear.com/SustainableMaterialTire.

“We continue to make progress towards our goal of introducing the first 100 percent sustainable-material tyre in the industry by 2030,” said Chris Helsel, Senior Vice-President, Global Operations and Chief Technology Officer at Goodyear. “The past year was a pivotal one toward achieving this goal. We researched new technologies, identified opportunities for further collaboration and utilised our team’s tenacity to not only demonstrate our capabilities to produce a 90 percent sustainable-material tyre, but to also produce a tyre with up to 70 percent sustainable-material content this year. Our team continues to showcase its innovation and commitment to building a better future.”

Tegeta Green Planet and Shine Energy, both affiliated with Tegeta Holding, have launched a joint educational initiative to raise environmental awareness and a sense of responsibility among young people. The project addresses modern challenges such as environmental protection and sustainable development.

Company representatives are visiting schools across Tbilisi to hold informational meetings, presentations and workshops. The programme begins with presentations, followed by interactive games and activities designed to help students retain the information. At the end of each session, participants receive symbolic gifts and prizes as motivation.

Tegeta Green Planet focuses on teaching students the principles of specific waste management, including how to properly handle used tyres, batteries and oils. The sessions explain why proper waste management is essential for environmental protection and how it connects to the circular economy. Meanwhile, Shine Energy educates young people on the importance of energy, its everyday use and why developing renewable and sustainable energy resources is crucial.

The initiative is not limited to schools. In the near future, both organisations will expand their efforts to universities, aiming to broaden awareness about environmental protection, waste management and energy efficiency. The ultimate goal is to foster environmentally responsible attitudes among the younger generation, helping build a more sustainable and conscious society.

German chemical group WACKER has announced a price increase of up to 15 percent for its resins, dispersions and dispersible polymer powders produced at its European and US facilities. The adjustment takes effect on 1 June 2026, or as existing customer contracts permit. The move is designed to allow the company’s Polymers division to maintain high product quality, deliver technological innovations and provide superior customer service and technical support. It will also support investments aimed at securing future growth in key markets.

Rising costs for raw materials and logistics have forced the pricing measure, with the Polymers division being particularly affected. The recent conflict in the Middle East has caused significant disruptions across global commodity markets. As a direct result, prices for energy, raw materials and transportation have climbed sharply.

Despite the increase, WACKER remains focused on sustaining its commitment to customer support and long-term capability. The company underscored that the adjustment is necessary to continue meeting market demands while ensuring operational stability and future-oriented development across its focus markets.

Pirelli North America has launched its first closed-loop circular recycling initiative, marking a significant step in the company’s broader strategy to increase recycled and bio‑based content in its tyre production. The project has received the Tire Recycling Foundation’s Value Chain Collaboration Award.

The programme recovers scrap tyres generated during Pirelli’s own North American manufacturing process. These materials are sent to Bolder Industries, which applies ISCC PLUS‑certified pyrolysis technology to produce BolderBlack recovered carbon black. Pirelli then reintroduces this material into new tyre production at its North American facilities, partially replacing virgin carbon black. The effort is part of a wider Pirelli plan to expand such industrial ecosystems across the group’s production network, aiming to valorise waste by reintegrating recovered materials into tyre manufacturing.

Beyond the award, the initiative reflects Pirelli’s broader circularity approach, which includes ongoing work to boost recycled and bio‑based material usage. The company targets over 80 percent bio‑based and recycled content in its best‑performing products and forty percent in total production by 2030.

Claudio Zanardo, CEO, Pirelli North America, said, "The Rome plant is one of the most technologically advanced manufacturing facilities in Pirelli. This initiative reflects an approach focused on increasing the use of recovered materials within existing production processes. It is part of a broader effort to gradually integrate raw materials derived from recycled resources into our products while maintaining consistency in performance and quality."

Tony Wibbeler, CEO, Bolder Industries, said, "Our collaboration demonstrates that a traceable, mass-balance approach to tyre-to-tyre circularity is not only achievable, but it's ready to scale inside a premium manufacturing environment, meeting real performance and certification requirements at every step. This is the kind of progress the industry has been working toward for many years."
