Biomass utilities for high water content have very important signifi cance close future in Japan. Especially, London treaty for ocean disposal of wastes in 2007-6 has big problems to keep of sustainability provisions supply for our lives. We could calculate to exist total caloric thermal energy 124TJ⁄y (340GJ⁄dZ) in Pig wastes as domestic biomass energy. This study is doing fundamental experimental by thermal decomposition and combustion for Pig wastes. Thermal decomposition analysis investigates for gasifi cation and fi xed carbon combustion characteristics. Fundamental combustion experiment shows time dependent combustion process, ignition process, fl ame process and char combustion process.
