In Australia, The solid waste left over from wine-making could make a competitive biofuel, University of Adelaide researchers have foundPublished 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 (the leftover skins, stalks and seeds from wine-making).

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. The solid waste left over from wine-making could make a competitive biofuel, University of Adelaide researchers have found.
