Trinseo and ETB to Collaborate on Development of Bio-Based 1,3 Butadiene

Trinseo and ETB have signed a letter of intent to collaborate on the development of purified bio-based 1,3-butadiene.

Under the partnership, the companies will jointly explore opportunities to scale up ETB's unique single-stage process to produce bio-based 1,3-butadiene from ethanol using polyfunctional catalyst technology. The collaboration will initially focus on demonstrating the viability of sustainable ethanol-based synthetic rubber in support of green tyre production. To underline this mutual commitment, Trinseo, with ETB's support, will conduct a feasibility study to explore the construction of a dedicated bio-based 1,3-butadiene pilot plant in Europe. Once operational, it is intended that the pilot plant will include a purification unit to achieve a purity target of 99.7%.

Bio-based butadiene is considered a vital first component in the value chain for enabling the replacement of fossil-based raw materials with renewable sources, thereby reducing the environmental footprint of consumer products, such as performance tyres throughout their lifecycle. It also represents a key milestone in Trinseo’s transformation as a sustainable solutions provider.

Within the past six months, Trinseo achieved International Sustainability and Carbon Certification (ISCC) and has become the first synthetic rubber provider globally to gain mass balance certification. In addition, Trinseo recently announced a business collaboration with BASF in the area of circular feedstocks, with the aim of strengthening the efforts of both companies in the development and management of styrene with an improved environmental profile.

“Sustainability is at the heart of Trinseo and this new partnership with ETB enables us to move towards truly differentiated material solutions with a lower environmental impact than ever before,” said Francesca Reverberi, Vice President, Engineered Materials & Synthetic Rubber, Trinseo. “Our customers are increasingly seeking new ways to add renewable and bio-based raw materials along the value chain to support their sustainability goals. The ability to derive bio-based butadiene from ethanol with close to 100% purity enables our customers to develop more sustainable products without compromising on performance.”

Vladimir Trembovolsky, CEO, ETB, added: "ETB is driven by the idea of bringing bio-based butadiene to the industry through our proprietary, patented process - currently demonstrated at our pilot plant in Russia. By working closely with Trinseo, we aim to unlock new opportunities throughout the value chain from biomass to end product. We look forward to sharing technologies and expertise as we strive towards industrial production of renewably sourced 1,3-butadiene at a purification level of at least 99.7%. ETB believes that true adoption of bio-based monomers is only possible through close collaboration between industry players along the entire value chain. Our joint-partnership is a beacon for the industry thanks to the scale, reach and sustainable ethos of Trinseo."

It is anticipated that the pilot plant evaluation study will be completed by the close of 2021. Both companies share the long-term ambition of scaling up live production globally. (TT)

Solvay Accelerates Global Circular Silica Efforts

Solvay Accelerates Global Circular Silica Efforts

Solvay is expanding its global circular economy strategy by converting its Asian production of highly dispersible silica (HDS) to use certified circular raw materials. Beginning in 2026, its plants in Qingdao, China, and Gunsan, South Korea, will transition to using ISCC+ certified waste sand. This major initiative is projected to make over half of the region’s HDS output circular, directly aiding tyre makers in their goal of incorporating over 40 percent sustainable materials by 2030.

This transition provides tyre manufacturers with a cost-effective, high-volume circular Zeosil silica that integrates seamlessly into existing processes without the need for reformulation. The move builds on the successful conversion of Solvay’s Livorno, Italy, facility to using rice husk ash and reflects a coordinated, global shift towards circular sourcing. It also supports the broader sustainability goals of Solvay Silica, including the adoption of low-emission technologies like electric furnaces to minimise the carbon footprint of its products worldwide.

By pioneering circular silica from diverse feedstocks and regions, Solvay is fostering more resilient and sustainable supply chains through innovative partnerships across the entire value chain.

An Nuyttens, President of Solvay’s Silica Business unit, said, “Solvay’s circular silica helps improve fuel efficiency and EV range, offers long-lasting wear benefits, improves safety, while advancing sustainability. This is more than innovation - it’s a reinvention of how we source, produce and collaborate across the value chain.”
