INDUSTRY PROFILE - BY SANDRA DICK
whisky waste. Scottish biofuel start-up Celtic Renewables Ltd has just secured the go ahead to build a commercial demonstrator plant, which will produce over half a million litres of biofuel each year from whisky waste.
Working with Tullibardine Distillery, Perthshire, it will turn draff and pot ale into Biobutanol, a replacement biofuel for petrol and diesel.
While the whisky industry is powering ahead with a shift towards AD plants – much to the concern of farmers who fear the impact it will have on supplies and costs of whisky by-product related animal feed – Scotland as a whole has embraced the new world of bioenergy.
Spurred on by Scottish regulations that require most food producers to separate their food waste, plus a new Scottish Energy Strategy, AD plants are thriving.
There are currently more than 50 across the country, around half of which have gone online in the last four years. As coal and gas takes a back seat, Scottish food waste is, excuse the pun, stepping up to the plate, partly aided by Scots homes and businesses disposing of around 1.35m tonnes every year.
Paragon-e and Shanks Waste Management’s Energen Biogas plant in Cumbernauld alone generates enough renewable energy to power 5000 homes, while SSE’s Barkip plant in Ayrshire is the largest combined organic waste treatment and energy generating facility in Scotland, capable of processing up to 75,000 tonnes of organic and food waste annually, and producing 2.2MW of renewable electricity.
As a whole, the AD sector delivers 45MW of power and 11,000 cubic metres per hour of heat in Scotland. Charlotte Morton, Chief Executive of the Anaerobic & Bioresources Association, believes it can help the Scottish Government achieve its energy plans, and bring other benefi ts.
“Renewable heat and energy produced through AD can make an important contribution to the Scottish Government’s Energy Strategy goals, as well as reducing emissions from landfi ll, creating rural jobs and helping to restore degraded soils,” she said.
“Farmers, businesses and government are increasingly seeing fi rst-hand the multiple benefi ts that green gas delivers”.
