Scotland’s first biorefinery is well on its way to being built now, with the arrival of six purpose-built 130,000 litre fermentation vessels. These were constructed in the Netherlands for Celtic Renewables’ new plant in Grangemouth. The construction project was thrown off kilter by the Covid-19 pandemic, but it is now back on track to produce high-value low carbon biochemicals, and next generation biofuel from biological waste and residues. It is perhaps the first sign that Scotland’s goal of a low carbon green economy is closer to reality. Celtic Renewables will use microbiology expertise and modern process technology to produce around 50,000 tonnes of residues each year. And they will obtain the residues from the whisky industry, so adding value and sustainability to one of Scotland’s most important sectors. The whisky industry produces 1.6 billion litres of pot ale and 500,000 tonnes of draff which previously were used in animal feed. Professor Martin Tangney OBE, Founder and President of Celtic Renewables, was acclaimed for his process for producing biobutanol, a sustainable advanced biofuel and renewable chemical, from the by-products of the malt Whisky industry – a process he is commercialising as the Founder of Celtic Renewables. Professor Tangney set up the first centre for sustainable biofuel development in the UK – The Biofuel Research Centre – at Edinburgh Napier University in 2007.
