Bio ethanol is a product of the sugar fermentation process. What is more, it can be also obtained thanks to the reaction of ethylene with steam. The sources of sugar to produce ethanol are derived from fuel or energy crops, such as wheat, corn, willow, sawdust, Jerusalem artichoke and not only. It is a clear liquid with no colour, which is low in toxicity and causes almost no environmental pollution. For this reason, it perfect to use in a biofuel fireplace.
