COLUMBIA – Green Energy Biofuel made a second annual donation to the University of South Carolina’s Sustainable Carolina on April 17. The company collects used cooking oil from USC and other organizations and upcycles it into useable biofuel. Green Energy Biofuel, located on Congress Street in Winnsboro, graduated from the University of South Carolina’s Incubator Program in 2012. By donating 25 cents for every gallon collected, Green Energy Biofuel gave a total of $2,100 back to Sustainable Carolina to help fund new butterfly and vertical gardens on campus.
