The invention discloses a method for producing ethanol fuel from kitchen waste, belonging to the technical field of biology. The invention aims to reduce the environmental pollution of kitchen waste, and change wastes into valuable substances, thereby recycling the kitchen waste. According to the method, the kitchen waste, which contains rich starch, cellulose, fat, protein and the like, is comprehensively utilized with a biological bacterial liquid and an enzyme preparation. The biological bacterial liquid contains Bacillus licheniformis, Bacillus megaterium, Bacillus natto, Bacillus subtilis, Lactobacillus plantarum, Lactobacillus delbrueckii subspecies bulgaricus, Saccharomyces cerevisiae and Pichia pastoris. The enzyme preparation comprises amylase, cellulase, lipase, protease, pectinase and saccharifying enzyme. The method comprises the following steps: fermenting the kitchen waste, biological bacterial liquid and enzyme preparation in a fermentation tank at the constant temperature of 25-32 DEG C for 48-80 hours, distilling the fermentation broth, and rectifying to obtain the ethanol fuel.
