Green biotech firms to open factories in Grangemouth

Two green biotechnology firms have announced they will build new factories at Scotland’s Grangemouth site which will employ up to 460 people, in the first phase of projects to replace hundreds of jobs lost when the PetroIneos refinery closed down.

The projects by MiAlgae, a start-up based in Edinburgh which uses whisky waste to make fish-free Omega 3 oils, and Celtic Renewables, which uses whisky and agricultural byproducts to make chemicals, have won £10m in funding from the Scottish and UK governments to build new plants at Grangemouth.

MiAlgae’s founder and chief executive Douglas Martin said their Omega 3 plant would start production in the second quarter of 2026, employing 75 people. It uses whisky wash, a byproduct, of whisky production to produce plant-based Omega 3 for pet food and fish farm feed.

Martin said their modular plant, which has been given £3m by the UK and Scottish governments, can be rapidly expanded to eventually create up to 310 jobs. Celtic Renewables, which uses agricultural byproducts to make acetone, butanol and ethanol used in cosmetics, chemicals and has been given £6.23m to build a plant expected to employ 149 by 2030.

The projects are being funded by the Grangemouth just transition fund and are linked to the Project Willow programme run by Scottish Enterprise to replace the 400 jobs lost when Grangemouth’s refinery closed down earlier this year, fueling a political storm over mounting job losses from North Sea industries.

Its closure is believed to affect up to 4,200 other jobs in the wider supply chain, intensifying pressure on both governments and Scottish Enterprise to quickly bring in high value jobs.

Jan Robertson, Scottish Enterprise’s director of Grangemouth transition, said both firms were expected to be part of a closely integrated supply and production chain which connected waste and byproducts from farms, food producers and whisky distilleries with bio-energy and bio-technology companies.

The investment agency has been in talks with 140 firms interested in investing at Grangemouth: the long-term goal is to see a sustainable aviation fuel refinery and plastics recycling plants built there.

Hopes for more green industries to move to Grangemouth

Gillian Martin, the Scottish government’s net zero secretary, said she expected other green, low carbon industries such as plastics recycling and sustainable aviation fuel to set up in Grangemouth following the decision by the Scottish and UK governments to fund two bio-technology factories there (see earlier post).

She said the new MiAlgae plant at Grangemouth, which expects to employ 75 people making omega 3 oils for animal and fish farm feed from whisky waste from spring next year, was additional to the types of industries proposed by the Project Willow programme to attract major new employers to Grangemouth, published after PetroIneos announced it was closing its oil refinery there.

Speaking at the site of MiAlgae’s new plant, she said:

“The projects we are announcing today are outwith what we anticipated would be the main outcomes of Project Willow and that’s actually really exciting.

“Today we’re able to make announcements about tangible operations that are going to be here that are going to be providing highly skilled jobs. But I think the most exciting part of it is its future industries.

“It’s industries that are going to be displacing an awful lot of carbon intensive processes, like MiAlgae are doing today – meaning that we’re not importing fish oil from around the world, and we’ve actually got a more sustainable product, but highly skilled work as well.

“The only way to turn the terrible negativity – because people are losing their jobs in traditional industries like PetroIneos, who have made decisions that are outwith government control – is to step in and do what you say you’re going to do, and that’s actually facilitate replacement jobs happening in that area. And that’s what we’re doing here today. We’re only at the start of this.”
