Adelaide researches are converting grapes into biofuel
The University of Adelaide released findings yesterday that indicate the solid waste left over from winemaking could make a competitive biofuel. Published in the journal Bioresource Technology, the researchers showed that up to 400 litres of bioethanol could be produced by fermentation of a tonne of grape marc. Global wine production leaves an estimated 13 million tonnes of grape marc waste each year. Nationally it is estimated that several hundred thousand tonnes are generated annually and it is generally disposed of at a cost to the winery.
