"Scientists may have just made the breakthrough of a lifetime, turning discarded fruit peels and other throwaways into cheap, clean fuel to power the world's vehicles."
Dr. Henry Daniell in his lab at the University of Central Florida
"Daniell's technique - developed with U.S. Department of Agriculture funding -- uses plant-derived enzyme cocktails to break down orange peels and other waste materials into sugar, which is then fermented into ethanol. Corn starch now is fermented and converted into ethanol. But ethanol derived from corn produces more greenhouse gas emissions than gasoline does. Ethanol created using Daniell's approach produces much lower greenhouse gas emissions than gasoline or electricity. There's also an abundance of waste products that could be used without reducing the world's food supply or driving up food prices. In Florida alone, discarded orange peels could create about 200 million gallons of ethanol each year..."
