As we move into Q2 2025, we're pleased to share a snapshot of what's been a strong start to the year for Celtic Renewables, commercially, operationally, and publicly. Regular shipments of our green chemicals are reaching customers, and we've seen increasing interest from both government and media.
In recent months, we've welcomed new team members, hosted high profile visits from the First Minister and the Deputy First Minister of Scotland, received multiple award nominations and wins, and gained consistent media coverage. It's been a fantastic start to the year, and there's much more ahead.
Operations Update
The manufacturing performance in terms of fermentation success, total solvent production and throughput for the period of January to early April 2025 has continued to show strong improvement.
Fermentation success has improved across the period with our standard recipe of pot ale and reject potatoes at 84.5% (above our target of 75%). Our equivalent success rate for the same period in 2024 was just over 30%. As a result we have been able to increase throughput to 6 fermentations per week, with a target of 7 per week consistently by the end of 2025. In March we achieved 9 fermentations in 9 days with 8 successful, and so we are confident of achieving this target.
With throughput increasing, so too is our production of green chemicals, with regular shipments to customers being achieved (see below).
Project Willow Report & ABE Fermentation The recently announced Project Willow Report highlights key opportunities and technologies that could position Grangemouth as a low carbon manufacturing hub, to replace the petrochemical refinery, which is closing next month. The EY-authored report commissioned by both UK and Scottish Governments, evaluated over 300 low-carbon technologies, and identified nine projects with the potential to protect the future of Grangemouth, including ABE biorefining, where Celtic Renewables is the recognised global leader. There has been considerable media coverage on the report, and with that increased profile and with support expected from both governments, work is underway on plans to develop a world-scale biorefinery in Grangemouth as part of Project Willow
Government Recognition
Celtic Renewables welcomed two Scottish Ministerial visits to the Grangemouth biorefinery during Q1. Deputy First Minister Kate Forbes toured the site in January, followed by a visit from First Minister John Swinney in March, coinciding with the release of the Project Willow Report.

Regular Shipments of Green Chemicals
Since our last update on the first tanker release, we have continued to send regular shipments of our green chemicals to customers, in partnership with our distribution partner, Caldic. The photo to the right shows one of the latest tankers being filled last week, ready for shipment to Caldic in Chesterfield.
