Renewable Coproduct LBDS, Braskem Announce Bio-Acetone Production Platform for Corn-Ethanol IndustryLallemand Biofuels & Distilled Spirits and Braskem have announced an innovative bio-acetone production platform for the corn-ethanol industry. (Source: Braskem)Montreal/Canada – Lallemand Biofuels & Distilled Spirits (LBDS), a global leader in yeast, enzymes, microbials and nutrition; and Braskem recently announced an innovative bio-acetone production platform for the corn-ethanol industry that enables producers to generate a new coproduct alongside ethanol. 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.
