Abstract:
In Japan, industry kitchen wastes with a high water content (up to 80 weight %) disposed from such commercial premises as restaurants and food stores have usually been treated by incineration. With a better treatment method in mind, we have developed an ethanol and methane fermentation system for the kitchen waste, in which starch is converted to bio-ethanol, whereas biogas (methane) is generated from the residue and other substances (proteins, fat, and like). Furthermore, we have verified stable system operations for both ethanol and methane fermentation processes for periods exceeding 90 and 150 days, respectively, with a total energy conversion efficiency of 79%.
