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.

Solvay has announced that it will optimise the soda ash production capacity at its Torrelavega site in Spain from 600 kilotonnes to 420 kilotonnes, effective from the third quarter of 2026 and pending the required consultation process. This decision is a direct response to ongoing global oversupply and persistently high energy and carbon costs in Europe.

By optimising its operational level, the company aims to strengthen the long-term competitiveness and sustainability of its remaining production at the facility. The Torrelavega site will continue to serve regional customers by focusing on soda ash and premium sodium bicarbonate, with supply guaranteed through both local operations and Solvay’s global network. Importantly, sodium bicarbonate production will remain unaffected.

This adjustment also supports the company’s commitment to the energy transition, including a major biomass initiative designed to significantly reduce coal usage at the site. As a result of the capacity reduction, a net decrease of up to 77 positions is expected. Solvay is committed to managing this transition responsibly and will engage closely with employee representatives to develop socially supportive solutions and measures for those impacted.

Etienne Galan, President of Solvay Soda Ash & Derivatives, said, “Solvay is taking decisive steps to enhance the competitiveness and sustainability of its soda ash operations. Soda ash is critical for essential applications, and Solvay remains firmly committed to the business. We are strategically investing now to cement our competitiveness for decades to come, including the deployment of carbon neutral soda ash processes as part of our energy transition roadmap. At the same time, we urgently need the regulatory framework to align with our industrial reality and the investments that are needed for this transformation.”

Germany's rubber industry continues to face significant headwinds, with fresh data from the German Rubber Industry Association (wdk) revealing a persistent downturn. The figures show employment falling for the fifth year in a row, while production levels have declined for the fourth consecutive year, underscoring the sector's struggle to regain its footing.

The association attributes this stagnation to waning enthusiasm for German rubber goods in both domestic and international markets. Michael Berthel, wdk Chief Economist, described a fundamental shift in procurement behaviour, even within Germany. He noted that purchasing decisions are now driven almost exclusively by price, a stark departure from the historical emphasis on quality and reliability. This change has opened the door to intense international cost competition, placing immense pressure on Germany's medium-sized suppliers. Berthel highlighted that prohibitive domestic costs related to energy, bureaucracy, taxation and labour make it nearly impossible for these firms to compete effectively. Consequently, many are compelled to relocate their investments abroad as a necessary escape from these local burdens, even though their preference would be to maintain and revitalise their operations within Germany after years of strategic transformation.

Against this backdrop, wdk President Michael Klein issued an urgent appeal to the federal government. He acknowledged that the broader struggles of German industry are well documented but stressed the immediate need for decisive political intervention. Klein called for concrete measures to stimulate demand and bolster the nation's competitive edge within Europe without further delay. He warned against allowing the rubber sector to decline quietly, emphasising its critical role in essential areas such as healthcare, infrastructure, security and mobility.

Punia Metox Private Limited has commenced production at a new manufacturing facility in Thottambedu, Tirupati, Andhra Pradesh, with operations starting on 12 February 2026.

The plant has an initial production capacity of 12,000 tonnes a year. Its structural design allows capacity to be doubled within four to six months, providing scope for rapid scale-up as demand grows, the company said.

Punia Metox said the facility has been equipped with modern technology to support operational and energy efficiency, safety, sustainability and consistent product quality. The company added that the plant has been designed to enable smooth and seamless operations from the outset.

The expansion forms part of Punia Metox’s strategy to align capacity growth with customer requirements and strengthen its position as a long-term supply partner. The company said the new unit reflects its focus on customer satisfaction, ethical business practices and value-based growth.

Cabot Corporation said it can now produce circular reinforcing carbons in the Asia-Pacific region after validating manufacturing capability at its plants in Cilegon, Indonesia, and Tianjin, China.

The materials are produced using tyre pyrolysis oil derived from end-of-life tyres and an International Sustainability & Carbon Certification (ISCC) PLUS mass-balance approach. With the addition of the two Asian sites, Cabot said it now has circular reinforcing carbon production capacity across Asia, Europe and the Americas.

Tyre manufacturers are pursuing targets to increase sustainable material use in tyre production, with many aiming for 40 per cent by 2030 and 100 per cent by 2050, the company said. Cabot’s circular reinforcing carbons are designed as a drop-in replacement for conventional carbon black, allowing manufacturers to increase sustainable content without affecting tyre performance.

Aatif Misbah, Vice-President and General Manager for sustainable solutions in Cabot’s reinforcement materials segment, said: “This achievement reflects our deep commitment to delivering sustainable solutions across Asia Pacific and globally. Scaling our circular reinforcing carbon capabilities helps strengthen our role as a trusted partner to the tire industry, while helping to drive meaningful sustainability progress. Looking ahead, we remain focused on supporting our customers’ evolving needs and helping enable a more sustainable future.”

Cabot’s facilities in Ville Platte, Louisiana; Mauá, Brazil; and Valasske Mezirici in the Czech Republic had previously demonstrated circular reinforcing carbon production capability. The products are ISCC PLUS-certified and marketed under the recovered category of Cabot’s EVOLVE Sustainable Solutions platform.

The company said it has 13 ISCC PLUS-certified sites supporting circular reinforcing carbon production across Asia, Europe and the Americas, along with two certified masterbatch and compounding sites in Europe.
