Trinseo (NYSE: TSE) and ETB have signed a letter of intent to collaborate on the development of purified bio-based 1,3-butadiene. This will see the two companies combine their respective technology and process expertise to accelerate the development of viable, renewably sourced material solutions.

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 tire 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 tires 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
