A couple of months ago I joined in the hand wringing
that the increasing demand for bio-fuels was driving up the cost of beer because former barley fields were growing crops destined for ethanol plants. Now it appears that this doesn't have to be and either/or sort of proposition. Researchers in Abertay’s School of Contemporary Sciences have received a grant
to investigate the possibility of using the spent grains from brewing in the production of bio-fuels. Adds a new dimension to self-proclaimed beer activist Chris O'Brien's
advice: "Drink beer. Save the world." In fact in an entry from last April
he mentioned that Coors is already using some of its waste in ethanol production.
