Celtic Renewables

In uniquely combining the whisky by-products, Celtic Renewables Ltd adapt the traditional Weizmann Fermentation process (also known as ABE fermentation) to a brand new and entirely sustainable novel substrate - not only providing a sustainable disposal route for the by-products of one of the UK’s largest and most iconic industries, but also integrating renewable energy production with environmental sustainability and carbon reduction, by producing sustainable biobutanol as a direct replacement for fossil road fuel to help meet the EU mandated biofuel targets, together with a sustainable source of other high value products. Celtic Renewables Ltd is initially focused on the £4 billion Scottish Malt Whisky industry as a ripe resource for developing biobutanol.  The pioneering process combines the two main by-products of whisky production (Pot Ale and Draff) to produce high value renewable products, including biobutanol. In a distillery, only 10 percent of what flows out of the distillery is future whisky- the rest is Draff and Pot Ale. The whisky industry annually produces 1,600 million litres of pot ale and 500,000 tonnes of draff which could be converted into biofuel as a direct substitute for fossil-derived fuel, thereby reducing oil consumption and carbon dioxide emissions, while also providing energy security – particularly in remote/rural areas where the whisky industry is prevalent. The Celtic Renewables Ltd production process also produces other sustainable chemicals, acetone and ethanol, as well as high grade sustainable animal feed.
