Leftover solid grape waste from winemaking could be used to produce competitive alternative fuel. Researchers from the University of Adelaide, Australia, are investigating the potential of transforming waste that is left over from the winemaking industry into biofuel. The researchers showed that as much as 400 liters of bioethanol could be generated by fermentation of a ton of the solid grape waste annually, which would be beneficial on many levels, including to wineries in Australia, which currently must pay for the disposal of an estimated several hundred thousand tons of…
