- Celtic Renewables renewed a three‑year pot ale supply agreement with Rosebank Distillery.
- Over the prior three years Rosebank supplied over 4,600 tonnes of pot ale to Celtic's Grangemouth biorefinery located under four miles away.
- Celtic's demonstrator converts pot ale into 500 t/yr of bio‑based chemicals that deliver >60% lifecycle carbon savings vs fossil equivalents and can reduce manufacturers' Scope 3 emissions.
- Celtic secured more than £16M (£5M Scottish Enterprise, £5M private investors, £6.23M Grangemouth Just Transition Fund) toward planning a £120M industrial‑scale biorefinery in Grangemouth.
Partnership extension
Celtic Renewables renewed its three-year supply agreement with Rosebank Distillery, under which Rosebank sends pot ale from its Falkirk operations to Celtic’s biorefinery in Grangemouth, located less than four miles away; over the prior three years Rosebank supplied more than 4,600 tonnes of pot ale from the production of a few thousand casks.
Conversion process and benefits
At its commercial demonstrator, Celtic converts pot ale into roughly 500 tonnes per year of bio-based chemicals that are chemically equivalent to fossil-derived alternatives and suitable for consumer and industrial products; using pot ale feedstock yields lifecycle carbon savings of over 60% compared with fossil equivalents and supports reductions in indirect Scope 3 emissions by replacing fossil inputs.
Scale-up funding and plans
Celtic secured more than £16 million in public and private funding toward planning and constructing a proposed £120 million industrial-scale biorefinery in Grangemouth: £5 million from Scottish Enterprise, £5 million from existing private investors and £6.23 million from the Grangemouth Just Transition Fund awarded by the Scottish Government.
