MONTREAL, QC, Canada & PHILADELPHIA, July 28, 2026 - Lallemand Biofuels & Distilled Spirits (LBDS), a global leader in yeast, enzymes, microbials and nutrition, and Braskem (B3: BRKM3, BRKM5, and BRKM6; NYSE: BAK; LATIBEX: XBRK), the largest polyolefins producer in the Americas and global leader in the production of biopolymers on an industrial scale, today announced an innovative bio-acetone production platform for the corn-ethanol industry that enables producers to generate a new coproduct alongside ethanol. Combining LBDS' proprietary fermentation technology with Braskem's bio-acetone recovery process, the solution creates a new revenue stream for biorefineries while maintaining ethanol production performance and providing access to a guaranteed demand for all bio-acetone produced.

"Pairing Lallemand Biofuels & Distilled Spirits' expertise in yeast and fermentation with Braskem's knowledge of biochemicals and biopolymers is a natural fit," says Craig Ammann, Vice President of Business Development for LBDS. "LBDS has served ethanol producers for decades and we continuously look for options to help boost their bottom lines and shield them from market volatility. This is a unique way to do that, based on strategic partnerships."

After five years of collaborative development and validation, Braskem and LBDS are now making the technology available to the U.S. ethanol industry. The companies have engineered an innovative yeast strain to enable bio-acetone production during fermentation, without affecting performance. Braskem developed bolt-on technology to separate the resulting bio-acetone from ethanol and will be responsible for all bio-acetone sales and market development. Acetone is a mature market with global demand of over 8 million tons per year, serving segments that are seeking new solutions from renewable sources.

"The team at LBDS brought their expertise in yeast and their extensive knowledge of the ethanol industry, complemented by our experience in chemicals and bioproducts, to make this collaboration a success," says Cirilo Vieira, Business Development Director - Renewables & Biochemicals at Braskem. "We are eager to offer this sustainable acetone alternative to our customers. It is a significant step for the petrochemical industry toward a sustainable future, in every sense."

Bio-acetone is a drop-in replacement for fossil-based acetone and can be used in cosmetics, paints and coatings, acrylics, adhesives, and personal care applications. It is 100% renewable, benzene-free, phenol-free and verifiable through a C14 test.
