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 Rubber Board of India has launched a series of educational videos as part of the iSPEED (INROAD Skilling and Production Efficiency Enhancement Drive) programme, an INR 1.50-billion initiative aimed at enhancing skill development, quality improvement and infrastructure building within the natural rubber sector. This launch comes as the plantation activities under the larger Project INROAD (Indian Natural Rubber Operations for Assisted Development) in Northeast India approach completion, shifting focus towards productivity and quality enhancement through modern training and facilities.

The newly released video series targets nearly 300,000 rubber growers in the region, covering five essential processing areas: Rubber Tapping, Rain Guarding, Grading, Rubber Sheet Making and Scientific Smokehouses. To ensure broad accessibility, the modules have been produced in Assamese, Bengali, Hindi and Malayalam, enabling effective communication with diverse stakeholders across the natural rubber ecosystem.

The official release of the videos was conducted by Executive Director M Vasanthagesan, alongside Rubber Production Commissioner Dr Siju T Nair, other senior Board officials and representatives from the Indian tyre industry. Developed over the past year with technical assistance from the Rubber Board and the Rubber Research Institute of India, the educational content combines animation with real-life field demonstrations to simplify complex scientific practices for easy adoption.

Project INROAD represents a unique collaboration between the Indian tyre industry and the Rubber Board, with support from Apollo Tyres, CEAT, JK Tyre and MRF. Over the last five years, this partnership has facilitated new rubber plantations across approximately 180,000 hectares in 113 districts of Northeast India, establishing it as the country’s largest plantation development programme of its kind.

Mohan Kurian, Chairman, INROAD Project, said, "Skill development and adoption of scientific practices are essential for improving both productivity and quality in the natural rubber sector. These multilingual videos will serve as an effective training resource for growers and complement the Rubber Board's ongoing extension efforts across the country.”

Sanjiv Saxena, Convener, ATMA Supply Chain & Resources (SCR) Group, said, "The objective of the participating member companies under INROAD is to ensure that rubber growers benefit the most from a stronger natural rubber value chain. By improving productivity and quality, we aim to help farmers realise better returns while strengthening the sustainability of the entire ecosystem."

Muraligopal, who played a key role in coordinating the development of the videos, said, "These videos are the result of close collaboration with the Rubber Board, RRII and field teams across the Northeast. Their guidance and support helped us develop practical, farmer-friendly training modules based on scientific best practices."

Zeon Corporation has finalised the construction of a new bench-scale facility at its Tokuyama Plant in Shunan City, Yamaguchi Prefecture, dedicated to advancing the efficient production of butadiene from sustainable ethanol sources. The project, which broke ground in July 2025, represents a strategic move to establish a naphtha-independent raw material supply chain, thereby bolstering both corporate sustainability and the broader transition towards a carbon-neutral society. The facility is slated to commence full-scale operations in January 2027, with the ultimate goal of achieving commercial viability by 2034.

A commemorative ceremony took place at the plant site on 31 July 2026, drawing a total of 46 attendees. The gathering included official representatives from Japan’s Ministry of Economy, Trade and Industry (METI), the New Energy and Industrial Technology Development Organization (NEDO) and local governmental bodies from Yamaguchi Prefecture and Shunan City. Also present were delegates from the Yokohama Rubber Company, the construction contractor and various affiliated firms, alongside Zeon’s leadership, including Akira Honma, the Corporate Officer and Tokuyama Plant Manager.

This initiative forms one half of a dual-themed research and development programme undertaken in partnership with Yokohama Rubber, under the auspices of NEDO’s Green Innovation Fund. The collaborative effort is focused on the social implementation of technologies for synthesising both butadiene and isoprene from renewable biological materials by the 2030s. As part of this process, Zeon is set to produce a prototype polybutadiene rubber using the output from the new bench-scale facility, while Yokohama Rubber will subsequently manufacture test tyres from this material and conduct performance evaluations on test tracks.

Both companies have outlined a clear roadmap, intending to finalise the core technology for societal deployment by 2030 through the operation of a larger pilot plant, with full-scale commercialisation targeted for 2034. The bench-scale facility is a critical precursor in this phased approach, providing essential data for the scale-up process.

The broader project encompasses two selected NEDO themes, both subsidised through the Green Innovation Fund. The first involves the highly efficient synthesis of butadiene from ethanol, with technical cooperation from the National Institute of Advanced Industrial Science and Technology. The second focuses on biotechnological pathways to directly produce butadiene and isoprene from plant-based materials, involving partnerships with the Institute of Science Tokyo and RIKEN. Both tracks aim to supplement synthetic rubber feedstocks and support closed-loop recycling, aligning with Japan’s 2050 net-zero emissions goal by fostering long-term industrial innovation.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly Natural Rubber Statistical Report for June 2026, a month defined by price resilience amid conflicting market forces. The provisional reopening of the Strait of Hormuz triggered a sharp 20.29 percent drop in Brent crude oil prices to USD 85.40 per barrel. However, this bearish signal was counterbalanced by persistent supply constraints from El Niño-related weather disruptions across major producing regions.

Physical rubber prices posted broad-based gains across most grades. SMR-20 rose 1.39 percent to USD 2.32 per kilogramme, while STR-20 gained 2.61 percent to USD 2.55 per kilogramme. RSS-3 and RSS-4 advanced 4.98 percent and 5.88 percent to USD 3.09 and USD 2.84 per kilogramme, respectively, though latex eased 1.44 percent to USD 1.94 per kilogramme. On the trade front, China's imports surged 7.14 percent month-on-month, while India and Viet Nam declined. Export growth was recorded for Cambodia, Viet Nam and Indonesia, though Thai shipments contracted.

Global production for 2026 is projected at 15.310 million tonnes, up 2.3 percent from 2025, driven by gains in Thailand, China, India and Malaysia. However, June output fell 3.7 percent year-on-year to 1.207 million tonnes due to seasonal wintering and El Niño-related weather disruptions. Malaysia, Indonesia and Cambodia have introduced new incentive and governance measures to strengthen their sectors. Global consumption is forecast to grow 0.7 percent to 15.411 million tonnes in 2026, with June consumption rising 3.3 percent to 1.300 million tonnes, led by China and India amid steady tyre and EV-related demand.

Currency markets saw the Malaysian ringgit trade between RM3.96 and RM4.08 against the US dollar, while the Thai baht ranged from 32.56 to 33.24. In futures trading, the SHFE September 2026 contract averaged 17,580.68 CNY per tonne, down 0.45 percent month-on-month, while the SGX September contract averaged USD 2.24 per kilogramme, up 1.75 percent, with both reflecting tightening supply and firm downstream demand.
