Old Newspapers + Secret Ingredient = Cheap Biofuel
The benefits of the newspaper-bacteria biofuel production process are many. Because it is based on natural fermentation, it needs less energy than conventional biofuel operations. Aside from the simplicity of the process, the use of a recycled material rather than a food crop such as corn is a big plus. Since butane is a drop-in fuel, it can be substituted for gasoline without needing any engine modifications, which gives it an edge over ethanol. According to writer Kathryn Hobgood Ray at Tulane, butane also contains more energy than ethanol and it is less corrosive to fuel pipelines, and it has a far lower carbon footprint than gasoline.
