About us

Celtic Renewables is widely regarded as one of the most innovative biotech companies in Europe, having developed a patented and proven process that converts biological residues from by-products and waste into sustainable green chemicals, driving the global shift to a circular economy.

Our technology has successfully reinvented the century old Acetone-Butanol-Ethanol (ABE) fermentation process, bringing it back to a global scale. As a world leader in re-establishing this process, Celtic Renewables operates from Scotland’s first biorefinery in Grangemouth, at industrial and commercial scale.

Acetone, butanol, and ethanol are found in thousands of everyday products, from cosmetics and medicines, to cleaning products and paints. By converting by-products and waste from industries such as food, drink, and agriculture into green chemicals (bio acetone, bio butanol, and bio ethanol), Celtic Renewables provides access to cleaner, greener alternatives.

Our existing plant operating at Grangemouth is the launch pad for our ambitious global growth plans. This commercial demonstrator facility is integral to the Group’s current operations (both in the production of green chemicals and in supporting feedstock trialling activities) with learnings derisking our plans to build larger scale facilities across Scotland, the UK and internationally.

Celtic Renewables are part of the Just Transition scheme in Grangemouth which makes it an extremely exciting time to join the team as we progress with plans to build for our first full-scale biorefinery in Grangemouth. Significant progress is being made on the path to sanctioning this first full-scale development project in 2026. By joining Celtic Renewables, you’ll be part of an innovative team working at a world-leading biorefinery, helping to lead the green chemical revolution.
