Okla. St. professor turns soda waste into ethanol
STILLWATER, Okla. (AP) - An Oklahoma State University professor says she's found a way to turn byproducts from the production of soda pop into ethanol. Biosystems and agricultural engineering associate professor Danielle Bellmer says that by adjusting the pH levels she has found that the leftover materials from soda manufacturing can be converted into ethanol. She said she's been testing process since last spring. The pH is a measure of acidity. Companies currently must remove the acidity from the byproduct before sending it to a wastewater treatment center. Bellmer said she's been working with students in the biosystems and agricultural engineering departments to conduct the testing.Â
