Bioethanol or simply "ethanol", as fuel for the operation of fireplaces, is produced through the fermentation of products of vegetal origin like sugar cane, potatoes, sugar beet and cereals, among others. It is considered a renewable energy source, 100% green, which respects the environment and does not contribute to global warming. Hence the name "bio" ethanol. From the combustion of bioethanol are released carbon dioxide (CO2) and water (H2O). These are the same products produced by our breathing, they are harmless substances. This is undoubtedly one of the reasons why bioethanol fireplaces are considered as clean and innovative products.
