Bioethanol (C2H5OH) is an alcohol coming mainly from biomass, exploitable as an environmentally compatible fuel that can partially be used in place of fossil fuels. Currently, a mixture of gasoline and bioethanol is commercially available, the E85, composed of 85% ethanol.
In this experiment, waste paper will be used as raw material for the production of ethanol through the digestion with a safe commercial enzyme and fermentation with regular grocery store yeast. Ethanol will be then monitored through the use of either an ethanol sensor or a dye that, reacting selectively with alcohol, will change colour revealing its presence.
