Abstract
The invention relates to a method for treating waste material. The method comprises the steps of: a. converting the waste material into a slurry, e.g., by adding water; b. adding enzymes to the slurry and allowing the enzymes to extract sugars from the slurry by enzyme saccharification; c. separating the liquid content of the slurry from the solid waste content to give a liquid; d. converting the liquid to an ethanol-water mixture; and e. concentrating or separating the ethanol-water mixture to give ethanol. An apparatus for treating waste material according to the method is also provided.
