In this paper, environmental and economical evaluation of the excess biogas transport, storage and the utilization system from biogas plant in the individual dairy farm was carried out. The results of the analysis for the S town, Hokkaido, are following.1. As a result of comparing the environmental loading in the influence to global warming, the PSA method, and the system for transporting the methane was the most predominant.2. The system for transporting the biogas without refining concerning the economical efficiency, is the most predominant. Only in this case, balance for 10 years is surplus.The most appropriate alternative in the current is an option transported without refining the biogas. The methane gas concentration and gas yield of the biogas greatly influences this result.The future problem is more accurate examination of gas transport, storage and future prospect of utilization system by using actual data such as gas yield of biogas plant which constructed in the S town.
