According to some researchers from the University of Adelaide, Australia, it is now possible to produce biofuel from grapes waste. The researchers analyzed the waste of grapes such as Cabernet-Sauvignon and Sauvignon Blanc, which seem to be better than other biomasses for this purpose, because of their amount of carbohydrate in the marc, in the seeds and in the stems.
For every ton of natural material, through the fermantation process, we can obtain up to 270 liters of bioethanol, but using special acids and enzymes we can even reach 400 liters!
The big news is that the biofuel obtained from wine waste is a cheaper alternative to conventional biomass. Kendall Corbin, co-author of the study, says: “It’s complicated to produce liquid biofuel using biomass obtained from plants, because of its complex structure. Using marc, the process becomes easier and cheaper. Marc is easily available, it is cheap and it has the right type of carbohydrates that can easily ferment”.
