Scottish green chemicals firm, Celtic Renewables, has secured £16.23 million in public and private funding to scale its production of high-demand green chemicals.
The funding comprises £5 million in new investment from Scottish Enterprise, Scotland’s national economic development agency, and £5 million from Celtic’s existing private investors, alongside £6.23 million from the Grangemouth Just Transition Fund that was awarded by the Scottish Government in December.
The latest investment was announced by Scotland’s Secretary for Climate Action and Energy Gillian Martin on a visit to Celtic Renewables’ biorefinery at Grangemouth today.
Celtic Renewables will use the fresh investment to fund the planning and development of a new £120 million industrial-scale biorefinery at Grangemouth with 10x the production capacity of the company’s current facility.
Celtic currently operates a commercial demonstrator biorefinery at Grangemouth. It uses ABE fermentation to produce bio-acetone, bio-butanol, and bio-ethanol from locally sourced waste and by-products including pot ale from whisky distillation and rejected potatoes.
Commenting on the news, Ms Martin said, “Celtic Renewables is an outstanding example of the innovation and ambition that is driving our move towards net zero, and this further investment by Scottish Enterprise will help the company scale up, create high‑quality jobs and build new skills for the local workforce.
“During Scottish Apprenticeship Week, it is also particularly important to highlight how this package – including new support for pathways into employment – will open up opportunities for people across the area. By backing pioneering technologies and investing in our future workforce, we are laying the foundations for a more sustainable, resilient and prosperous Grangemouth.”
Celtic Renewables CEO Mark Simmers said, “Our demonstrator facility in Grangemouth is Scotland’s first biorefinery and has been operational since 2023. In that time, we’ve proven that our patented ABE fermentation process is scalable and commercially viable, de-risking future projects.
Mr Simmers went on, “Today, demand for our bio-based chemicals far outstrips current production capabilities at our demonstrator plant. Companies globally are seeking to switch to green chemicals to cut their indirect Scope 3 emissions and meet increasing customer demand for more sustainable products.
“With this latest investment, we’re now poised to take the knowledge gained at our demonstrator plant and scale to full industrial-level operations in Grangemouth.”
Celtic Renewables was founded in 2012 as a spinout from Edinburgh Napier University. With this latest investment, the company has secured more than £90 million in total private and public funding.
