Toyo Tires is exhibiting a concept tire that uses 90% sustainable materials at the Tokyo Auto Salon 2024. On January 12, at the Tokyo Auto salon, Toyo Tires presented its Sustainable Concept Tire. The tire, using 90% sustainable materials is a step forward towards a more viable future mobility. Among the raw materials necessary to commercialize tires, materials that are recognized to contribute to reducing environmental impact. Until now, the highest ever usage rate of sustainable materials in one of our tires was 50%. This latest development was made in the Open Country tires used in the 2024 Dakar Rallye.

Goodyear has created a 70% sustainable-material content version of its Assurance all-season tire. The company is making strides toward its aim of developing a tire that is 100 percent sustainable by 2030.

Recently, an expert in tire-derived carbon black Martin von Wolfersdorff shared his views on the prospects recovered carbon black (rCB) in tire-to-tire recycling. In his press release Mr. von Wolfersdorff said he appreciated it when tier one carbon black companies spoke about rCB. The expert says top carbon black producers attend rCB workshops, presentations or conferences organized by Wolfersdorff Consulting, and there are ample opportunities for collaboration between the rCB and the CB industry, some of which have been highlighted in his Carbon Black World 2018 presentation in Düsseldorf (see image below). There is way to go, Martin von Wolfersdorff says.

During the latest international trade fair IAA Mobility, Continental presented innovative technologies that set new standards. One topic of focus is sustainability. As early as 2021, the tire manufacturer focused on the use of silica from agricultural waste, polyester from recycled PET and other renewable and recyclable materials with the Conti GreenConcept concept tire. Continental has now incorporated many of these technologies into its series tires. With the UltraContact NXT, the company launched the most sustainable series tire to date last year. This underlines Continental’s claim to be the most progressive manufacturer in the tire industry when it comes to sustainability.

Nokian Tyres says it has been striving to make the world a safer place for decades. In the company’s recent press release, it was announced Nokian reached yet another milestone, as it introduces its most sustainable tire yet. The Nokian Tyres Green Step concept tire is a masterpiece of sustainable innovation with its ambitious design consisting of 93% of the materials either recycled or renewable. It moves the company even closer to its goal: by the year 2030, 50% of all raw materials used in Nokian Tyres’ tires will be recycled or renewable

With recycling and sustainability making headlines in the mainstream news, recovered carbon has ever growing market potential. Its enhanced use would lead to reduction of CO2 footprint, cost reduction to carbon black users, less price volatility and even in some cases performance benefits over carbon black grades. It is used as a substitute for virgin carbon black, or applied in combination with its virgin counterpart; the research of the recycled material’s applications, its blending properties and value is still ongoing, and it was deeply discussed during Recovered Carbon Black Forum held on May 21-22 in Berlin, Germany organized by Smithers Rapra and Martin von Wolferstorff.

e-RubberCon is an international conference organized by the French Association of Rubber and Polymer Engineers (AFICEP) under the auspices of the International Rubber Conference Organization (IRCO) which AFICEP is a member of. As its name suggests, the conference is devoted to problems of rubber industry, including rubber and tire recycling, as this year its main motive is “Environment and Recycling: A Strategic Challenge for Rubber Materials.” This year, Robert Weibold – a tire recycling and pyrolysis expert from Vienna, Austria – speaks at e-RubberCon about “Challenges, trends and opportunities for end-of-life tires from a French perspective”.

Globally, over one billion tires become unusable yearly, presenting a valuable resource for the circular economy. Efforts to manage end-of-life tires (ELTs) are underway, with various stakeholders collaborating to improve recycling rates and reduce tire dumping. The World Business Council for Sustainable Development (WBCSD) Tire Industry Project (TIP) has facilitated workshops to foster cooperation among stakeholders in regions such as the US, Europe, and China. While progress has been made in ELT recycling rates, challenges remain, including policy inconsistencies and inadequate market reporting.

Large industrial companies are involved at a crucial point in the process of sustainable tire recycling. AZUR network coordinator Christina Guth welcomes the joining of Zeppelin Systems GmbH at the turn of the year: "With the Zeppelin systems, the tire recycling cycle is efficiently closed." Zeppelin is one of the world's leading system manufacturers that specializes in the development of components and plants for the handling (storage, conveying, mixing, dosing and weighing) of high-quality bulk materials. Zeppelin Systems has many years of experience in blending plants and also covers all processes in the rubber and tire industry down to the smallest detail.
