Sumitomo Rubber Industries, a global tyre and rubber company based in Japan, announced on their website last week that they have succeeded in synthesising new biopolymers that will accelerate the development of the ultimate fuel-efficient tyres. This is as a result of joint research undertaken with Associate Professor, Seiji Takahashi of Tohoku University, Associate Professor, Satoshi Yamashita of Kanazawa University, and Professor Yuzuru Tozawa of Saitama University, states Sumitomo Rubber Industries.

The company claims that its research team recently discovered that the use of modified tomato enzymes (developed as part of their prior research) as a polymerisation catalyst, makes it possible to select polymer initial monomers at will. Based on this discovery, they have succeeded in synthesising biopolymers incorporating initial monomers that are more conducive in improving tyre performance. According to Sumitomo Rubber Industries, through its ongoing research, the company aims to contribute to the realisation of sustainable societies by developing tyres that take fuel efficiency to all new heights for the 2040s and beyond.

The rubber and tyre company further states that its research team had previously succeeded in synthesising a biopolymer not found in nature, by first identifying the segment of natural rubber synthase that plays a key role in determining polymer chain lengths, and then replacing this segment with a similar segment of a specially modified enzyme derived from tomatoes.

Having since furthered its research on modified tomato enzymes, the company recently discovered that the use of modified tomato enzymes weakens initial monomer selectivity. Sumitomo Rubber Industries claims that this in turn allows for synthesis, starting from monomers other than the initial monomers typically involved in the initiation of polymerisation. In addition, by taking advantage of this newfound characteristic, the company has also synthesised entirely new biopolymers, incorporating initial monomers that they have selected at will.

Sumitomo Rubber Industries recently announced the results of its research at the 33^rd Annual Association for Advancement of Industrial Crops (AAIC) Meeting held in Bozeman, Montana (USA) from 9-12 October, 2022. Moving forward, as per Sumitomo Rubber Group, the company will continue working to contribute to the realisation of sustainable societies. It plans on doing this through its ongoing efforts to ensure a stable supply of natural rubber while providing tyres that combine safety and peace of mind, with a reduced environmental impact, the company claims.

Continental Tires has achieved a major sustainability milestone with all its European tyre production facilities now certified under the International Sustainability and Carbon Certification (ISCC) PLUS standard. The certification extends to plants in Lousado (Portugal), Puchov (Slovakia), Korbach (Germany), Sarreguemines (France), Otrokovice (Czech Republic) and Timișoara (Romania), along with the supporting Industria Textil do Ave textile plant in Portugal. The company's Hefei facility in China has also earned this recognition, expanding Continental's sustainable manufacturing network globally.

The ISCC PLUS certification verifies Continental's compliance with rigorous traceability and documentation requirements for renewable and recycled materials used in tyre production. This system enables the company to track sustainable inputs throughout the manufacturing process using the mass balance approach, which allows gradual incorporation of eco-friendly materials while maintaining existing production systems. Continental is currently increasing its use of certified materials, including bio-based synthetic rubbers and circular-process carbon black, as part of its strategy to include over 40 percent sustainable materials in tyres by 2030.

As a globally recognised standard established in 2010, ISCC certification promotes climate-friendly, deforestation-free supply chains across multiple industries. It covers sustainable biomass, recycled materials and renewable resources, providing a framework for transparent, responsible sourcing. For Continental, this achievement represents both a validation of current sustainability efforts and a foundation for future innovations in eco-conscious tyre manufacturing. The company's growing network of certified facilities demonstrates its commitment to reducing environmental impact while maintaining product quality and performance standards across its global operations.

Jorge Almeida, head of Sustainability for Continental Tires, said, “The ISCC PLUS certification of all our European tyre plants is an important milestone and a strong signal for a more sustainable industry in Europe. But we're not stopping there. Our plants in other regions will follow step by step, like our Hefei plant, which is already certified. We have a strong ambition to make our tyre production more sustainable worldwide across our entire supply chain.”
