Biodiesel from NYS Fair butter sculpture

Nine hundred pounds of butter will end up fueling the vehicle fleet at the SUNY College of Environmental Science and Forestry (ESF). "Thirty-seven percent of the college's fleet runs on some form of renewable energy, including biodiesel," said ESF President Cornelius B. Murphy, Jr. "Using the butter sculpture is a unique way to fuel the ESF fleet."
After the fair’s 12-day run ends on Labor Day, the butter will be brought to the ESF biodiesel production facility. The first step is to clarify the butter to remove the water and milk proteins. He said it takes about nine pounds of butter to make a gallon of biodiesel, so this year’s 900-pound sculpture should yield around 96 gallons of biodiesel.
