Method for producing ethanol using whey, and use of the ethanol and gaseous production byproducts

Abstract

The invention addresses the problem of creating a simplified and efficient method for producing ethanol from whey, which is also sustainable and provides substantial use of the production byproducts and production residual products. 1. The invention relates to a method for producing ethanol using whey, characterised in that a sugar content of the whey is concentrated to form a thickened whey by water removal (1), in that subsequently, with addition of enzymes and yeast, the thickened whey is fermented (2), wherein the fermentation (2) takes place over at least six days, in that subsequently, the fermented thickened whey is fed to at least one distillation process (3) or at least one distillation stage (3) and is distilled to form ethanol, wherein at least one production byproduct (4) and / or at least one production residual product (5) is collected, discharged or picked up for further processing.
