It seems that wine is much more than tasting it. Besides being delicious and offering several benefits for the body, now also serves as fuel. Yes, as you read it, let’s see how grapes can be gasoline.
A research from the University of Adelaide in Australia concludes that it is feasible to produce up to 400 litres of bioethanol through the fermentation of one ton of grape waste. That is to say, most of the carbohydrates present in these grape residues could be transformed into ethanol through a fermentation process, with a production of up to 270 litres per ton of grape waste.
But this study is not the only one that determined that grapes have this power, as a Gironde company has developed a fuel based on grape waste. That is why, after the study and its application in the company, there are those who predict that bioethanol could become a clear alternative to gasoline and diesel.
Grapes as fuel
Specifically, Citram Aquitaine has the Interlink LD Euro 6 bus from Scania, and is committed to a vehicle adapted to long distance travel that works with bioethanol produced by Raisinor France Alcools. The bus of this company does not work with diesel, like many others present in the market, but with fuel made from grape waste, that is, the solid part of the berry after the extraction of juice.
The alcohol contained in this residue will be extracted and distilled to obtain ED95, which is translated into bioethanol, which emits 95% less CO² than a conventional fuel. This way, we also obtain a type of sustainable fuel that does not harm the environment, something that has long been pursued as an alternative to other energies.
In addition, it is a “km 0” biofuel because the waste is collected in the vineyards of the Gironde, in the same area. This month of November the bus already will circulate with this bioethanol and will operate between the areas of Mont-de-Marsan and Dax.
As explained by the company, its production potential would supply 1,000 vehicles locally. And they comment that by using the waste products of the local wine industry to manufacture the fuel that is used in some of their vehicles, they are joining the green intelligence movement.
A vehicle with ED95 consumes more because the production of ethanol is half that of diesel, and it is more expensive to buy compared to a vehicle of such characteristics. The bioethanol-diesel comparison is important because it represents 50% less nitrogen oxides and 70% less particles.
