UTILIZATION OF BIOMASS FOR FUEL AND ENERGY PRODUCTIONS WITH SUBCRITICAL WATER
Utilization of large amount of waste biomass is very important in 21st century. Environmentally friendly sub-and supercritical water was used for the conversion of waste biomass to useful fuels and clean energy with large-scale plants. The first topic is the production of thermal energy from bad-smelling waste biomass. 2-step subcritical water oxidation process was developed to incinerate large amount of livestock excrement or sewage sludge completely and safely to carbon dioxide, water and nitrogen gas. The thermal energy was recovered using high-pressure heat exchanger efficiently. The second topic is the production of bioethanol from paper sludge. Effective bioethanol production was developed using combined process of subcritical water hydrolysis and enzymatic saccharization. This process realized more than 80 ％ of high glucose yield and no production of furfural compounds, which are inhibitors of ethanol fermentation. The last topic is the production of powdery fuel from the mixture of garbage and waste plastics. New technique using subcritical water was developed to convert refractory waste mixture to high quality and sulfur-free fuel with high heat of combustion.
