Livestock excreta requires proper treatment by Law on Promoting Proper Management and Use of Livestock Excreta, because livestock excreta causes odor problems and eutrophications problems, if it is released in environment. Compost production has been utilized for the treatment of livestock excreta, but new livestock excreta treating process is desired, because the amount of fertilizer that can be supplied to a specific farmyard area limitations. Methane fermentation process that is expected as energy recovery technology of livestock excreta has not been widely used because this process requires energy-and cost-consuming treatment of fermentation sludge and wastewater. On the other hand, supercritical water gasification process doesn't circumvents these problems by thermochemical conversion at high temperature. Thus, it is expected to be one of the new livestock excreta treating process. This paper presents our project of conducting experimental study of supercritical water gasification process by treatment of livestock excreta in a demonstration plant.
