• Discharged approximately 19 million tons per annual, food waste gets attention as unrecyclable biomass in Japan. However, because of its high moisture contents, effective utilization is not developed and is becoming a great interest. In this study, two bio-ethanol technologies are reported: Bioethanol from food waste and orange squeeze leftover. The bioethanol production technology derived from food waste have been developing with a focus on sugar and starch in food waste. Firstly, food waste can be converted into energy such as ethanol and oil with high efficiency. Secondly, it was clarified that the combination of the ethanol plant and the gasification and melting system can greatly reduce CO_2 emission. Furthermore, the technology of bioethanol production which is derived from orange squeeze leftover has been developed. In this application, a new heat recovery system using non-recovered waste heat at an existing drying plant of juice factory has been developed. New yeast with tolerance to limonene, which is a fermentation inhibitor specific to the citrus, has also been developed.
