Ethanol Produced From Cheese


With help from a state agricultural grant, a Wisconsin company has successfully tested technology that converts cheese waste into ethanol. According to Joe Van Groll, owner of DuBay Ingredients, the process starts with the cow and ends with the cow. Two years ago, Van Groll received a $29,000 grant from the Agricultural Development and Diversification Grant program to research and develop a process for the conversion of cheese whey permeate into ethanol. The process also creates a high-nutrition cattle feed by extracting two by-products: probiotic feed supplement and salt. State agriculture officials say the cheese waste to ethanol technology could save cheese makers millions of dollars annually in disposal costs. :: Wisconsin Ag Connection
