Celtic Renewables

Celtic Renewables is a Scottish biotechnology company founded in 2012, based in Edinburgh.

The company specializes in converting low-value organic waste, particularly by-products from the Scotch whisky industry and rejected potatoes, into high-value green chemicals and advanced biofuels using patented ABE fermentation technology. Their product portfolio includes biobutanol, bioacetone, and bioethanol, which serve as sustainable alternatives to fossil-derived chemicals. The company operates Scotland’s first biorefinery in Grangemouth, which became operational in 2023. Celtic Renewables focuses on providing green chemical supplies to manufacturers across various sectors, including cosmetics, cleaning products, pharmaceuticals, and automotive. Their mission is to lead in ABE fermentation and promote a sustainable, circular economy by transforming waste into valuable products, thereby supporting the transition away from fossil fuels.
