Celtic Renewables is a Scottish industrial biotechnology company focused on producing bio-based chemicals through a modernized acetone–butanol–ethanol (ABE) fermentation process. The company converts low-value residues into higher-value products, using clostridial fermentation techniques rooted in academic research.
Its primary outputs include bio-acetone, bio-butanol, and bio-ethanol, derived from locally available feedstocks such as by-products from whisky distillation and other agricultural materials. These renewable chemicals serve markets in solvents, coatings, fuels, and personal care, offering drop-in, lower-carbon alternatives to petrochemical equivalents while promoting circular use of regional waste streams in the UK.
