Bridgestone has initiated a collaborative research project with Universitas Indonesia, Public University Corporation Yokohama City University (Yokohama City University), and Public University Corporation Maebashi Institute of Technology (Maebashi Institute of Technology) focused on the genetic analysis of para rubber trees. The partnership draws on tree samples and genetic data from Bridgestone’s own natural rubber farm in Indonesia, combined with the advanced capabilities of the academic institutions. The primary goal is to develop a marker assisted selection technique that can identify elite trees, characterised by high and stable yields, at an early stage. A formal signing ceremony took place at Universitas Indonesia on 7 April to mark the beginning of this joint effort.

Sustainability is central to Bridgestone’s management philosophy, reflected in its business model that links operations to carbon neutrality, a circular economy and nature positivity across the entire value chain from production to renewal. This research directly supports that vision by aiming to improve the sustainability of natural rubber. Ultimately, the company seeks to contribute to a more circular and regenerative business model where natural rubber production becomes increasingly efficient and environmentally responsible.

A stable supply of natural rubber is essential for tyre manufacturing and safe mobility, yet para rubber trees grow only in narrow equatorial bands and face threats from climate change and disease. With global vehicle ownership rising, demand for natural rubber is increasing, creating pressure to boost productivity without expanding farmland into forests. Bridgestone has therefore pursued multiple technological paths, including disease diagnostics and big data driven planting optimization on limited land. The company also supports smallholder farmers by sharing these technologies and providing training based on know‑how from its own farms, thereby enhancing productivity, improving livelihoods and strengthening the long-term sustainability of natural rubber.

In this specific research initiative, Bridgestone supplies latex samples and existing genetic information from its rubber trees. Universitas Indonesia handles the extraction of DNA and RNA data, while Yokohama City University and Maebashi Institute of Technology perform genetic analyses to pinpoint genes linked to rubber productivity. Together, they will build a marker assisted selection method for rapid, high-precision identification of elite trees, significantly shortening traditional breeding timelines that once took decades. After validating the technology and establishing propagation and nursery systems, Bridgestone plans to replace ordinary trees with elite varieties over the medium to long term, thereby raising productivity and stabilising yields within finite land resources.

Prof Dr Tito Latif Indra, M.Si, Dean of the Faculty of Mathematics and Natural Sciences, Universitas Indonesia, said, "In this project, the Faculty of Mathematics and Natural Sciences, Universitas Indonesia (FMIPA UI), will play a key role in supporting the scientific framework of the project by leveraging its expertise in molecular biology and genetic data acquisition. This collaboration is such an important foundation in strengthening FMIPA UI's academic contribution in impactful global research. Through research in the field of sustainable natural resources, we are trying our best to reinforce the ecosystem of global natural rubber production and provide significant innovation to support sustainable rubber plantations in Indonesia."

Yukihisa Shimada, Director, Kihara Institute for Biological Research, Public University Corporation Yokohama City University, said, "In this project, Yokohama City University will serve as a strategic and technical advisor, supporting collaboration with Indonesian government agencies and the establishment of research infrastructure. Through international collaboration, we will drive high-precision genome analysis and the selection of promising lines, contributing to the creation of scientific knowledge for sustainable resource use."

Kensuke Nakamura, President, Public University Corporation Maebashi Institute of Technology, said, "In this joint research, Maebashi Institute of Technology will lead the bioinformatics analysis, contributing to the advancement of natural resource research through a data-driven approach. As a public university, we are dedicated to fostering both locally grounded research and international research partnerships. By leveraging these strengths, we seek to generate impactful knowledge that will contribute to building a more sustainable society."

Masashi Otsuki, Executive Director, Institute of Advanced Technology, Bridgestone Corporation, said, "By co-creating with stakeholders across the natural rubber industry and promoting the sustainable use of natural rubber, Bridgestone strives to achieve the corporate commitment of ‘Ecology: Committed to advancing sustainable tire technologies and solutions that preserve the environment for future generations’ described in its Bridgestone E8 Commitment.

Kuraray America, Inc. marked National STEM Day on 8 November by spotlighting a community educational event that brought together 15 of its volunteers and students from the Houston Japanese Supplementary School at San Jacinto College for a day of hands-on exploration and discovery.

Participants engaged in activities illustrating how science, technology, engineering and mathematics (STEM) converge in chemical manufacturing. Experiments with superabsorbent polymer beads explored chemistry and material properties, while a tour of the college’s facilities introduced industrial equipment. Students also learned about water filtration and distillation processes and how mathematical concepts underpin scientific and engineering applications.

One student showed particular interest in the distillation tower, linking the experience to the Kuraray Group’s contributions to everyday life and its mission of achieving for people and the planet what no one else can. The event also benefited KAI volunteers, who shared technical knowledge, exchanged perspectives and learned alongside potential future scientists and engineers.

Kuraray America thanked Reiko Fuwa and Tomohiro Tani for coordinating the visit, Hans Vandommele for sharing his expertise and all 15 KAI volunteers. The company also expressed appreciation to San Jacinto College for facility access and to the Houston Japanese Supplementary School students for their curiosity, enthusiasm and thoughtful questions.

Liberty Tire Recycling attended the 2026 SEMA Show in Las Vegas, held from 3–6 November at the Las Vegas Convention Center. The automotive aftermarket event, one of the industry's largest, drew over 160,000 attendees from the automotive, tyre and transportation sectors to review new products, technologies and business opportunities.

The Lakin Tire brand, a consistent SEMA exhibitor, once again used the show to reinforce industry relationships and present Liberty's tyre collection, recycling and sustainable resource management capabilities. Personnel from Grade/Used Tires, Commercial Truck Tires, Metals, Recycling and Collection, together with corporate and regional leadership, met customers, suppliers and industry professionals from around the world.

The booth received existing and prospective customers from numerous tyre and automotive segments during the week. Costco Wholesale Corporate Office, United Tires and UTU Wholesale were among the organisations that stopped by to examine Liberty Tire's products, services and nationwide reach. The company viewed the event as an effective forum for monitoring emerging market trends and demonstrating its position in recycling and sustainability, alongside its focus on innovation, workforce development and circular economy principles.

A memorable moment came when a high school shop teacher and students, attending through a special educator programme, toured the booth to learn about tyre recycling and industry operations. Liberty team members provided industry insights, outlined career pathways and acknowledged educators' contribution to developing future skilled trades professionals, supplying tyre inflation gauges for classroom use.

Laufenn, Hankook's associate brand, earned a ‘Good’ ratingwith an overall score of 2.2 for its G Fit 4S in the Auto Bild Allrad all-season SUV tyre test published on 8 October 2026 (issue 41). The tyre competed credibly against 11 rivals from established premium marques, finishing competitively in a 12-strong field.

Wet handling proved a particular strength, with the G Fit 4S collecting the second-highest rating shared with other models. Aquaplaning resistance also impressed, as the tyre held its line until stability began to fade at roughly 100 kmph (62 mph). In snow, it recorded the third-shortest braking distance, matching two other contenders.

Testing spanned snow, wet and dry disciplines, each weighted equally in the final ranking, with a third-generation MINI Countryman serving as the test vehicle. Snow assessments were carried out in New Zealand, while European venues hosted the wet and dry evaluations. The jury's conclusion underscored Laufenn's value-focused positioning, finding the G Fit 4S a solid option for cost-conscious buyers.

Tyres Europe has underscored that tyres qualify as fully recyclable under ISO 22628:2002 and UN Regulation No. 133, describing the established methodology as a robust foundation for assessing tyre recyclability. The organisation recently set out its position on the matter.

The distinction between recyclability and actual recycling rates is central to the group's argument. Recyclability refers to the technical potential of a product and its materials to be recycled, while the real rate hinges on treatment capacity and demand for secondary raw materials. Regulatory frameworks should therefore separate the two concepts clearly and align with an internationally recognised standard.

Tyres consist of rubber compounds, chemical additives and reinforcing textile and steel cords, and at end of life they are separated into rubber, textile and steel fractions, all of which existing mechanical or chemical routes can recycle. Mechanical processing yields rubber granules and powders usable as secondary raw materials across many applications, recovered textiles can be further processed and valorised, and cleaned recovered steel can re-enter metal recycling and steelmaking.

Tyres Europe pledged continued cooperation with policymakers and value-chain partners to strengthen circularity and maximise recovery of valuable tyre materials in Europe, with the full paper available on its website.
