A Scottish company turning whisky waste into green chemicals just secured £16.23 million to build a massive new biorefinery at Grangemouth. The cash will help Celtic Renewables jump from demonstration scale to full industrial production, creating jobs and proving Scotland can lead the world in low-carbon manufacturing.
Where the Money is Coming From
The £16.23 million package breaks down into three clear parts.
Scottish Enterprise is putting in £5 million fresh equity. Existing private investors are matching that with another £5 million. The biggest slice, £6.23 million, comes from the Grangemouth Just Transition Fund, money the Scottish Government set aside specifically to protect and grow jobs as the old oil refinery winds down.
This is now the largest single investment ever made by Scottish Enterprise in a cleantech company.
What the New Plant Will Actually Do
Celtic Renewables already runs Scotland’s first biorefinery next to the Ineos site at Grangemouth. That demonstrator plant, opened in 2023, takes pot ale (the leftover liquid from whisky distillation) and draff (spent grains), plus rejected potatoes, and ferments them into bio-acetone, bio-butanol and bio-ethanol using a patented ABE process.
The new facility will be ten times bigger.
Construction cost is pegged at £120 million. When it opens in 2028 it will process 100,000 tonnes of waste a year and produce 20 million litres of sustainable chemicals that can replace fossil versions in everything from paints and pharmaceuticals to aviation fuel.
Why Grangemouth Matters So Much
Grangemouth has been Scotland’s industrial heartbeat for decades, but the PetroIneos refinery is closing in 2025 with the loss of hundreds of jobs. The Scottish Government has made the area ground zero for its “just transition” promise: no community left behind in the race to net zero.
Celtic Renewables is now the flagship project showing that promise can become reality.
During her visit to the current plant, Climate Action Secretary Gillian Martin said the investment “keeps Grangemouth at the heart of Scotland’s low-carbon future” and will “create high-quality jobs and build new skills for the local workforce.”
The Man Who Made It Happen
CEO Mark Simmers started the company in 2012 after spotting that Scotland throws away half a million tonnes of whisky co-products every year.
“We’ve spent eleven years proving the technology works at commercial scale,” Simmers told reporters on site. “Every litre we produce now has customers waiting. This funding removes the last risk for investors and lets us move fast.”
The company already has offtake agreements with major chemical buyers and is in talks with airlines for sustainable aviation fuel made from the same process.
Bigger Picture for Scotland
This is not just about one factory.
Scotland produces 1.2 billion litres of whisky annually, creating roughly 2.6 billion litres of pot ale, enough to fill 1,040 Olympic swimming pools. Right now most of that goes to animal feed or is spread on fields.
Celtic Renewables has shown it can turn that waste into products worth ten times more while cutting carbon emissions by up to 90% compared to fossil alternatives.
If the model rolls out across the country, it could create thousands of rural and industrial jobs and keep hundreds of millions of pounds circulating in the Scottish economy instead of being spent on imported oil-based chemicals.
The Grangemouth plant is only the beginning. The company already has planning permission for a second site in Belgium and is looking at locations in Ireland and Japan.
One local worker who has moved from the oil refinery to the biorefinery summed it up simply: “I used to make fuels that warmed the planet. Now I make fuels that help cool it. Same skills, better future.”
Scotland just showed the world how to turn its most famous waste product into its next great export.
