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. After five years of collaborative development and validation, Braskem (Philadelphia, Pennsylvania) 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. 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.
