Scotland toasts new whisky-powered bioenergy plant

Contracts have been awarded to construct a biomass combined heat and power plant at Rothes in Speyside, Scotland. By 2013 the plant will use the by-products of the whisky-making process for energy production. Of Scotland's 100 whisky distilleries, 50 are based in Speyside. Spent grains ('draff') and pot ale residue are usually transported off site by whisky distilleries. The 7.2MW Rothes project will instead burn the draff with woodchips to generate enough electricity to supply 9,000 homes. The pot ale will be made into a concentrated organic fertiliser and an animal feed for use by local farmers.
