The CNN film crew spent two days filming in various locations in Edinburgh and the surrounding area, including The Scotch Whisky Experience, Kingsbarns Distillery and Edinburgh Napier’s Sighthill campus, home of Celtic Renewables.
While at Sighthill, Nick Glass met with Prof Tangney and the Celtic Renewables scientists who are striving to revive a century-old technology to create a new biofuel using the byproducts from the whisky industry.
The company celebrated an exceptional year in 2015, producing the world’s first samples of an advanced biofuel – biobutanol – from the production residues of the Scottish malt whisky industry.
Prof Tangney said: “This international exposure shows the tremendous interest in what we are trying to accomplish at Celtic Renewables, but the interest from CNN also reflects the global attraction that Scotland holds and we are proud to be playing our small part in shaping the country’s future.”
