Yokohama Rubber developed a groundbreaking advancement in rubber technology—a highly crack-resistant rubber material crafted from nanoparticle-based polymers. 

This innovative development is the fruit of a collaborative endeavour with a distinguished research group led by Associate Professor Daisuke Suzuki from Shinshu University's Graduate School of Textile Science and Technology, along with RISM (Research Initiative for Supra-Materials). 

Leveraging the knowledge acquired from this partnership, further research is anticipated to yield safer and more durable tires and rubber products that prioritize human well-being and environmental sustainability. Remarkably, this newly created rubber material can be easily recycled without any degradation, promoting the principles of a circular economy.

The research project harnessed nanoparticle-based polymers synthesized through mini-emulsion polymerization, a widely recognized polymerization technique. By utilizing a nanoparticle-dispersed aqueous solution and evaporating the water content, a nanoparticle film—serving as the rubber material—was successfully produced. Notably, the incorporation of rotaxane molecules, also known as supramolecular compounds, within these nanoparticles as crosslinking agents significantly bolstered their resistance to crack propagation, eliminating the necessity for additional additives such as reinforcing agents. Additionally, the nanoparticle film contributed to the rubber material's exceptional elasticity.

Moreover, nanoparticle films composed solely of nanoparticles can be effortlessly decomposed by immersing them in a water-ethanol solution, representing a low environmental impact process. The highly volatile ethanol can be evaporated, allowing the water-ethanol solution to be returned to its original nanoparticle-dispersed aqueous state. This unique regenerative capability ensures that the nanoparticle film can be easily rejuvenated without any deterioration.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for January 2026, providing an overview of key developments in the global natural rubber sector.

As per the report, a notable price rise was observed this month, driven by a combination of surging crude oil prices and heightened demand from tyre manufacturers, especially in China.

Below is a summary of the latest trends and data points defining the NR sector:

Global NR production is expected to rise by 2.2 percent in 2026 to an estimated 15.324 million tonnes, according to recent statistics from ANRPC member countries. Global demand for consumption is expected to increase by 1.4 percent to around 15.602 million tonnes annually.

The tyre industry's recovery indications reinforce the market's resilience in the face of several global economic headwinds. The current state of the market indicates a time of consolidation. This comes after recent price increases and before the cyclical wintering season, which runs from February to May and is traditionally characterised by a more constrained worldwide supply.

Bekaert has achieved a significant sustainability milestone by securing ISCC PLUS certification for its steel tyre reinforcement products. This accomplishment highlights the company's dedication to driving innovation and working closely with tyre manufacturers to promote the widespread use of materials with high recycled content.

Historically, steel used for tyre reinforcement was not covered by ISCC PLUS. However, a partnership between Bekaert, ISCC and the certification body TÜV NORD successfully developed a structured certification path for tyre cord and bead wire with high recycled content. TÜV NORD played a key role by auditing Bekaert’s Burgos facility during a pilot phase, technically validating that the ISCC PLUS framework could be effectively applied to steel-based products. This validation paves the way for its wider acceptance in the tyre sector.

This certification builds upon the foundation laid by Bekaert’s own Recycled Content Standard, which previously set an industry benchmark for traceability and sustainable practices. The earlier standard's success was instrumental in encouraging ISCC to broaden its certification framework to encompass steel products. Although the Bekaert standard will remain valid during the transition, ISCC PLUS now offers a globally acknowledged system that guarantees uniformity and clear traceability throughout the entire supply chain.

This certification positions Bekaert as a leader in advancing certified tyre reinforcement, fostering industry-wide acceptance and generating shared benefits with tyre makers. For manufacturers, utilising ISCC PLUS-certified materials lends credibility to their sustainability assertions, simplifies the certification landscape and aids in meeting regulatory and market demands. Furthermore, their customers continue to gain from Bekaert’s dependable supply chain, which is now enhanced by verified sustainable sourcing.

Annie Xu, President – Rubber Reinforcement, Bekaert, said, "Achieving ISCC PLUS certification demonstrates our leadership in certified steel with high recycled content for tyre reinforcement. We are proud to have worked closely with ISCC and TÜV NORD to shape this framework, which will help our customers stay ahead of sustainability and regulatory expectations."

An ISCC representative said, "We welcome the successful completion of the certification process for steel tyre reinforcement under ISCC PLUS. This demonstrates that the ISCC framework can be applied to additional material categories while maintaining our established requirements for traceability and verification."

Samir Beqqal, Head of Carbon Traceability Business Entity Sustainability, TÜV NORD CERT, said, "Working with Bekaert and ISCC on this pilot certification was an important step towards applying ISCC PLUS principles to new material categories like steel. We are delighted that we were able to contribute our expertise to this process and help ensure that certified traceability and sustainability assurance can also be effectively extended to industrial materials now.”

Sri Trang Agro-Industry Public Company Limited (STA) is advancing Thailand’s agricultural digital transformation through its homegrown platform, the Sri Trang Friends application. Launched in 2019 with the vision of providing a comprehensive digital tool for rubber farmers, the platform has since evolved to serve a broader agricultural community, including palm growers. It is designed to streamline access to information, services and various support mechanisms, creating a direct link between the company, farmers and supply chain participants.

A key recent development is the introduction of the Friends Shop feature and the Friends Point rewards system. This enhancement integrates local merchants from communities nationwide into the application, allowing farmers to conduct convenient transactions while helping to lower their daily expenses. The points accumulated can be used as cash equivalents or exchanged for a wide range of benefits, including essential goods and services, thereby stimulating local economic activity. The platform’s utility has also been extended to Sri Trang Group employees and the general public, who can now earn and redeem points for discounts or payments at participating outlets such as supermarkets, fuel stations and coffee shops. This expansion ensures the app delivers practical, lifestyle-oriented advantages to a wider user base.

According to Executive Director Vitchaphol Sincharoenkul, the application was originally conceived under the concept of ‘One App, Complete Services for Rubber Farmers’ to strengthen farmer engagement, improve coordination efficiency and ensure fully traceable and transparent produce trading. Beyond these operational goals, it also opens new marketing channels for local communities and fosters deeper collaboration across the agricultural value chain. The company is actively broadening its network of partners to diversify the benefits and merchant options available to users.

Currently, the Sri Trang Friends platform has attracted over 150,000 registered users, with more than 40 community merchants across various regions either already onboard or preparing to join. This growth underscores the company’s commitment to leveraging a Thai-developed digital solution to empower modern farmers, reinforce local economies and drive sustainable long-term progress within the nation’s agricultural sector.
