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.

Zeon Corporation and Visolis Inc. have formalised their partnership by signing a binding term sheet, marking a pivotal advancement in the commercialisation of bio-based isoprene monomer and sustainable aviation fuel (SAF).

This collaboration, which now moves from technology verification towards project implementation, is built upon the progress made since their initial memorandum of understanding in March 2024 and the subsequent joint feasibility study announced in April 2025. Bio-based isoprene monomer serves as an essential component in the production of synthetic rubbers and various other materials, while SAF is increasingly recognised as a critical next-generation fuel for reducing carbon emissions within the aviation industry.

The newly established term sheet outlines a foundational agreement on the key elements required for a final investment decision. These include defining the business structure and the respective roles of each company, establishing technology and development strategies and advancing detailed engineering for the proposed production facility. Furthermore, the agreement covers the evaluation of potential sites, the process for engaging with suppliers, securing necessary regulatory approvals and planning the financing pathway.

The envisioned facility is set to commence commercial-scale output after successfully demonstrating mass production capabilities for biomass-based isoprene and SAF, utilising Visolis’ proprietary technology. Both companies are now committed to expediting the path to full-scale production and ensuring a steady supply of these sustainable products to the global market.

Zeon Corporation has deepened its commitment to digital chemistry through a strategic investment and partnership with Chemify Limited, secured via its corporate venture arm Zeon Ventures Inc. Chemify, a growth-stage UK enterprise, is reshaping molecular research by integrating digital tools with automated laboratory systems. Its proprietary Chemputation technology translates molecular targets into executable chemical code, which operates directly on robotic platforms to complete integrated Design–Make–Test–Analyze cycles without manual intervention. This closed-loop automation allows Chemify to explore previously inaccessible areas of chemical space while reducing the timeline from concept to synthesized compound by up to tenfold.

A cornerstone of Chemify’s capability is its recently inaugurated Chemifarm in Glasgow – one of the most sophisticated automated facilities in the world for molecular design and construction. The facility enables accelerated iteration and autonomous synthesis of novel small molecules, converting chemical code into tangible compounds with unprecedented efficiency. These advances are critical for developing functional, synthesisable molecules that can contribute solutions to urgent global issues spanning public health, energy efficiency and environmental protection.

Zeon has been at the forefront of adopting digital methodologies in chemical R&D, recognising their transformative potential from an early stage. This investment is positioned to strengthen Zeon’s internal digital chemistry efforts and catalyse the invention of novel materials capable of addressing complex societal needs. The move aligns with Zeon’s STAGE30 corporate strategy, which targets a rise in revenue contribution from four key growth sectors – Mobility, Healthcare and Life Sciences, Telecommunications and Green Transformation – to 48 percent by fiscal 2028. By backing pioneering enterprises and cultivating advanced materials, Zeon continues to advance its dual vision of a sustainable planet and a secure, progressive society.

Pyrum Innovations AG has welcomed the official recognition by French authorities on 17 January 2026, which classifies tyre pyrolysis oil (TPO) as a legitimate raw material for the chemical sector. This pivotal regulatory milestone for pyrolysis oil derived from end-of-life tyres substantially enhances the product’s integration into established chemical value chains. It also provides greater predictability for future purchase and partnership frameworks, thereby accelerating the development of industrial material cycles.

For Pyrum, which processes scrap tyres through pyrolysis to recover pyrolysis oil, industrial carbon black and steel, this decision underscores the critical need for standardised and reliable regulatory conditions. Such clarity is fundamental for scaling investments, production volumes and supply chains, particularly as the chemical industry and circular economy converge. The establishment of clear product categories is essential to ramp up the market for high-quality recycled raw materials.

The company remains committed to tracking further developments in France and the wider European dialogue regarding the classification and application of recycled feedstocks. Pyrum’s overarching objective is to expand industrial-scale recycling solutions for scrap tyres. This regulatory progress directly supports the company’s mission to secure long-term, quality-assured supply agreements with partners across the chemical industry, thereby advancing a more sustainable and circular economic model.

Pascal Klein, CEO, Pyrum Innovations AG, said, “The decision in France is an important step for the industrial use of pyrolysis oil from waste tyres. It supports a trend that we are seeing in many markets, where the chemical industry is seeking reliable, technologically robust and clearly classified alternative raw materials.”
