GRANADA, Spain, Nov. 3 (UPI) -- Spanish scientists say olive pits, also know as stones, can be turned into bioethanol and used as an alternative power source for gasoline or diesel.
The researchers from the Universities of Jaen and Granada said their finding presents the olive processing industry with an opportunity for recycling the 4 million tons of olive waste generated annually and sets a precedent for the recycling of waste products as fuels.
