Zeon Corporation has announced the development of Nipol BR1300, a novel hydrophilic styrene butadiene rubber (SBR) for winter tyres. Synthesised with a polybutadiene rubber base, the material delivers unprecedented hydrophilicity for tyre applications. Commercial production began in May 2025 at Zeon’s Tokuyama plant in Yamaguchi Prefecture.

As part of its strategic portfolio optimization, Zeon plans to phase out low-profitability products like ESBR-1 and NBR latex by 2026. However, it will continue manufacturing high-margin products, including ESBR-2, nitrile butadiene rubber and solution SBR. This shift underscores Zeon’s focus on advanced, value-driven rubber solutions.

Covestro India has entered into a strategic collaboration with CSIR-National Chemical Laboratory (NCL) through an innovative CSR initiative focused on developing sustainable upcycling technologies for polyurethane waste. This partnership aims to overcome existing recycling limitations by transforming discarded polyurethane materials into valuable chemical feedstocks, potentially revolutionising the material's circular economy.

This collaboration underscores both organisations' commitment to environmental innovation, leveraging NCL's advanced research infrastructure and Covestro's market leadership to address critical gaps in plastic circularity. Current polyurethane recycling methods, predominantly mechanical with some emerging chemical processes, face substantial challenges including material degradation, high energy consumption and hazardous byproduct generation. The project seeks to develop commercially viable chemical recycling solutions that maintain material integrity while minimising environmental impact.

Polyurethanes, widely used in furniture, automotive parts and insulation, present unique recycling difficulties due to their complex molecular structure. Most end up in landfills after use, creating significant sustainability challenges. By combining Covestro's industrial expertise with NCL's seven decades of chemical research excellence, the partnership aims to create breakthrough upcycling technologies.

Avinash Bagdi, Director & Head of Sales & MD Solutions India & Projects – Tailored Urethanes, said, "This partnership strengthens our commitment to finding innovative solutions for polyurethane waste and directly supports Covestro's vision of becoming fully circular. By developing effective methods to upcycle polyurethanes, we're taking concrete steps towards creating a more sustainable future in line with our corporate vision of driving the transition to a circular economy."

Dr Ashish Lele, Director of NCL, said, "CSIR-National Chemical Laboratory is excited to partner with Covestro (India) in this groundbreaking initiative to develop novel chemical upcycling methods for polyurethane waste. The conventional and electrochemical strategies we're developing address the critical limitations of current recycling technologies and align perfectly with our shared vision of a circular economy. This collaboration represents a significant step towards sustainable plastic management in India and globally, with potential to transform polyurethane waste into valuable chemical resources."

Zeon Corporation has begun building a pilot facility at its Tokuyama Plant in Shunan City, Yamaguchi Prefecture, to test a new method for efficiently producing butadiene from plant-derived ethanol. The demonstration plant, expected to start operations in 2026, will supply butadiene for manufacturing trial batches of polybutadiene rubber, bringing the company closer to commercialising this sustainable production process.

This project is a key part of a joint initiative between Zeon and The Yokohama Rubber Co., Ltd. to develop eco-friendly methods for producing butadiene and isoprene from renewable sources, with full-scale adoption targeted for the 2030s. Under the collaboration, Zeon will produce butadiene rubber at the new facility, while Yokohama Rubber will use the material to create experimental tyres and conduct performance testing. The data collected will help refine the technology ahead of larger-scale trials. The companies aim to finalise the production process by 2030 using an expanded pilot plant, with plans for industrial-scale commercialisation by 2034.

A ceremonial groundbreaking event took place on 10 July 2025, with 33 attendees, including local government officials from Yamaguchi Prefecture and Shunan City, construction partners and Zeon executives such as Chairman Kimiaki Tanaka and Tokuyama Plant Manager Akira Honma. The gathering included traditional safety prayers for the construction phase, marking the official start of this sustainability-focused industrial project.
