Two broiler chicken industries have been growing in the two districts in Japan. One is South Kyusyu and the other is Northern Japan. South Kyusyu district has been operating some chicken waste power generations with successful operation result, but not experience in Northern Japan. Chicken waste is to subject on environment issue such as foul smell and polluted water, and expected to utilize it as biomass energy. In this circumstance, a feasibility study in this district was conducted to show how it was feasible or not using IRR (Internal Rate of Return) method. This feasibility study shows us that less than 80,000 ton per year of chicken waste (mixture of broiler litter and lying egg litter) is high potential commercialization of the power generation system under the some of the conditions. Several findings are reported in this paper on cost of the reasonable treatment fee, and recent market trend of phosphorus fertilizer which is generated from ash of chicken waste as fuel of the plant.
