Celtic Renewables boosts green chemical production efficiencies

At the core of this partnership is Enzyme Supplies’ tailored enzymatic solutions, which are now being integrated into Celtic Renewables’ patented acetone-butanol-ethanol (ABE) fermentation process.
This innovation significantly enhances the breakdown of complex organic feedstocks – including by-products from the whisky industry – into fermentable sugars, enabling more efficient and scalable production of green chemicals.
Lorna Woodcock, head of research, technical & innovation at Celtic Renewables, said: “This collaboration is a major step forward in commercialising our technology at scale. By harnessing the power of Enzyme Supplies’ biocatalysts, we’re able to increase yields, reduce processing times, and expand the range of waste and by-product materials we can valorise. It’s a win-win for innovation and the environment.”
The enhanced process not only improves carbon savings, but also reduces reliance on fossil fuels, contributing to the UK’s and EU’s net-zero goals.
The partnership is already being piloted at Celtic Renewables’ bio-refinery facility in Grangemouth, with plans to expand the integrated solution across future plants.
Dr Jonathan R. Burns, technical director at Enzyme Supplies, commented: “Our enzymes are designed to optimise the bioconversion of bio-based feedstocks, and partnering with Celtic Renewables is a natural fit.
“Their unique circular economy model and commitment to sustainable innovation aligns perfectly with our mission. Together, we’re enabling a cleaner, greener future.”
