Braskem and Lallemand Partner on Bio-Acetone Technology

Braskem and Lallemand Biofuels & Distilled Spirits (LBDS) have unveiled a joint technology to produce bio-acetone from corn ethanol without impacting fuel yields. Aiming for commercial supply by 2028, the drop-in renewable solution targets high-demand sectors across North America and Europe.

Developed over five years, the process integrates LBDS’s yeast and fermentation capabilities with Braskem’s proprietary separation technology. Designed as an add-on unit for existing ethanol facilities, it enables ethanol producers to diversify revenue streams through high-value biochemicals.

Braskem will spearhead commercialization and global market development, targeting key industrial hubs in the US and Europe.

Serving an 8M-Tonne Global Market

With annual global acetone demand surpassing 8 million tonnes, the drop-in bio-acetone offers a direct, low-carbon alternative for conventional fossil-based solvents.

Target end-markets include cosmetics and personal care (solvents and makeup removers), paints and coatings, acrylics, and adhesives.

Cirilo Vieira, Director of Business Development for Renewable Energy and Biochemicals at Braskem:

Combining Braskem's biochemical capabilities with LBDS's fermentation expertise marks a significant milestone toward decarbonizing the petrochemical value chain.
