About

From by-products & waste to green chemicals

Celtic Renewables uses ABE (Acetone-Butanol-Ethanol) fermentation to produce bio-based alternatives.

A process that defossilises chemical production, adds value to industrial by-products and waste, and reduces the carbon footprint of everyday products.

Products

Bio-acetone

Used in a wide variety of applications including pharmaceuticals and cosmetics as a solvent and formulation ingredient. A sustainable alternative to fossil-based acetone.

Bio-butanol

A versatile solvent used across coatings, cosmetics, personal care, and speciality chemical applications. This is a lower-carbon alternative to conventional butanol.

Paint pours into cans on a production line in a factory. Workers manage clean equipment, ensuring smooth operation for paint production in vibrant colors.

Bio-ethanol

Widely used across several industries, our ABE (Acetone, Butanol, Ethanol) fermentation process also produces bio-ethanol.
