The Yokohama Rubber Co., Ltd. and Zeon Corporation have decided to work together to build a bench facility to showcase technologies for efficiently making butadiene from ethanol made from plant-based and other sustainable sources. Zeon's Tokuyama Plant in Sunan City, Yamaguchi Prefecture, will house the plant, which is expected to start up in 2026. It will make it possible to produce a specific quantity of butadiene and make it easier to gather the many types of data needed to develop mass manufacturing.

The New Energy and Industrial Technology Development Organisation (NEDO) chose two research and development themes in 2022 for its project, ‘Development of Technology for Producing Raw Materials for Plastics Using CO2 and Other Sources’, which is one of the Green Innovation Fund Projects of NEDO. This initiative is in line with one of those themes. The National Institute of Advanced Industrial Science and Technology (AIST), National University Corporation Institute of Science Tokyo (formerly Tokyo Institute of Technology) and the national research and development agency RIKEN are working together to develop two technologies that will allow for the highly efficient production of butadiene and isoprene from plant-based and other sustainable materials in the 2030s. Zeon and Yokohama Rubber are working towards the social implementation of these technologies. The bench facility to be installed at the Zeon plant is part of initiatives based on the theme ‘Highly Efficient Butadiene Synthesis Using Ethanol’.

The experiment at the new bench facility will show how to use a very effective catalyst to turn ethanol made from plant-based and other sustainable materials into butadiene. This will be the first stage in establishing the technology's use for the large-scale manufacturing of synthetic rubber from plant-based and other sustainable ingredients. From the butadiene produced at the bench facility, Zeon will create a prototype polybutadiene rubber (butadiene rubber). Yokohama Rubber will use the butadiene rubber to create prototype tyres and test the tyres' performance to gather information for a larger-scale technology demonstration.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for December 2025, providing an overview of key developments in the global natural rubber sector.

As per the report, the natural rubber market is positioned in a strategic accumulation phase that belies superficial price indicators. A critical analysis reveals that while US Dollar-denominated prices showed a slight pullback, this was overwhelmingly due to the appreciation of the Thai Baht rather than a decline in intrinsic value. In Thailand, a key producing nation, local currency (THB) prices remained fundamentally firm, underscoring a resilient domestic price floor that continues to support the long-term upward trend.

This underlying market strength is concretely evidenced by price movements in Malaysia. During the reported period of consolidation, Malaysian SMR-20 prices increased by 2.08 percent and latex prices rose by 2.35 percent. These gains in a major producing hub directly contradict a bearish narrative and confirm that underlying global demand continues to outpace available supply. The current market behaviour is therefore characterized as a ‘cumulation pullback’, a necessary corrective foundation following earlier strong gains, designed to build liquidity before the next advance.

Fundamental data supports this outlook. Global natural rubber production for 2025 is anticipated to grow by a modest 1.4 percent. Although the latest demand figures show a marginal adjustment of -0.7 percent, overall market sentiment remains resilient, bolstered by clear recovery signals from the tyre industry. Critically, the market is now entering the seasonally tight ‘wintering’ period from February to May, when latex production naturally declines. The consolidation and strategic accumulation observed in December 2025 have thus established a solid platform. With supply set to contract and demand holding firm, all conditions are aligned for a sustained price rally as the market moves into early 2026.

Effective 1 November 2025, the Kerala Government has increased the assured market support price for RSS IV grade rubber. Under the state's Rubber Production Incentive Scheme, the new rate is set at INR 200 per kilogramme, representing a rise from the previous INR 180.

To avail this benefit, rubber producers must first renew their enrolment in the incentive programme. This requires submitting a current land tax receipt accompanied by a self-declaration form. Subsequently, growers can have their verified sale invoices uploaded via their respective Rubber Producers’ Societies. The dedicated online portal for this process is now active for submissions.

The administration has instructed all Rubber Producer Societies to ensure the prompt and accurate uploading of these invoices for their registered members. Should any society experience technical problems or difficulties accessing the portal, immediate support is available by contacting the relevant Field Office or Regional Office for resolution.

Birla Carbon, a leading global manufacturer and supplier of high-quality carbon materials, and Kennesaw State University (KSU) have expanded their enduring partnership with the launch of Birla Carbon India Study Abroad Program in January 2026. This programme, backed by a USD 184,000 contribution from the carbon materials manufacturer, will send undergraduate students from KSU’s College of Science and Mathematics to India for collaborative research. Participants will first develop their projects during the spring semester at KSU before travelling to the Birla Institute of Technology and Science (BITS) in Goa for summer work alongside local faculty and peers.

This endeavour builds upon nearly a decade of collaboration, which since 2014 has funded research opportunities for over 110 KSU students as Birla Carbon Scholars. In its inaugural year, the programme will facilitate hands-on research for up to 12 students, marking a significant evolution in the longstanding alliance between the university and the global company. The initiative is designed to provide immersive, cross-cultural scientific training, equipping students with global perspectives and advanced research skills crucial for their future careers in science and technology.

Sharing his thoughts about the program, Terence Norman, HR Head, Americas, Birla Carbon, said, “Birla Carbon is now in its 15th year of partnership with Kennesaw State University overall, and over the years, we have seen phenomenal growth and development opportunities for the students here in the College of Science and Mathematics. Our ongoing commitment is driven by a genuine belief in making a positive impact not only for the students who participate in this programme but also for the impact their solutions can have across major industries and society at large. Fifteen years mark not just a partnership but a shared journey of growth and discovery. Birla Carbon’s purpose is to ‘Share the Strength’, and Kennesaw State gives us an opportunity to do that first-hand.”

Kadian Callahan, Associate Dean for Student Success and Community Engagement, KSU – College of Science and Mathematics, said, “We’re excited to partner with Birla Carbon to bring this opportunity to our students. The college’s focus is on providing quality undergraduate research experience to students, and this programme allows students to take their work beyond campus and into an international research setting. Students can begin their research at Kennesaw State and continue it at BITS in India, working closely with faculty and peers at both institutions. That continuity strengthens their projects and creates opportunities for shared publications with KSU and BITS faculty and students.”

Bekaert has achieved an industry milestone with Dramix Loop, its most sustainable steel fibre. This product is the first in its sector to be manufactured industrially using steel reclaimed from end-of-life tyres, creating a new benchmark for circular construction. It directly tackles a significant circularity challenge within the tyre industry by transforming discarded tyre cords into a high-performance resource. This innovative approach preserves the material’s inherent tensile strength while bypassing carbon-intensive reprocessing, resulting in a near-zero carbon footprint with an exceptionally low Global Warming Potential of only 0.0436 kg CO₂eq per kg.

The launch reinforces the longstanding leadership of the Dramix brand, which already offers concrete reinforcement solutions that substantially reduce material use and CO₂ emissions. Dramix Loop further advances this legacy, providing fibres with very low contamination and high tensile strength suitable for diverse applications, including industrial flooring, precast elements and ultra-high-performance concrete. Beyond performance, it supports major sustainability frameworks like LEED and BREEAM, aids in compliance with the EU Taxonomy and helps companies reduce their Scope 3 emissions, thereby assisting owners and developers in meeting critical environmental, social, and governance objectives.

Eric Peeters, Divisional CEO Sustainable Construction, said, “Just like our other Dramix products, Dramix Loop ticks all the boxes: safe, smart and sustainable. It’s less labour-intensive, reduces CO₂ up to 80 percent compared to traditional reinforcement and leverages our structural design capabilities. And the circular aspect adds even more value, because with end-of-life steel, the carbon footprint is close to zero.”
