Using massive butter sculptures from the annual Pennsylvania farm show,
the USDA partnered with Philadelphia's Black Gold Biofuels to repurpose
the butter as biodiesel, the New York Times reports.
The impetus was an 800-pound sculpture of Benjamin Franklin and the Liberty Bell. Each year the Pennsylvania Farm Show, held in Harrisburg, commissions a masterpiece made out of butter. In 2007, the organizers solicited suggestions for what to do with the work after the farm show ended.
Dr. Haas submitted the idea of making biodiesel fuel out of it, and that is what was done. “It had never been reported in the scientific literature,” he said.
