A study was conducted on a system to refine biogas generated from a biogas plant, which uses cow slurry as its main ingredient, and use the bio-methane as a regional energy supply source. Based on the data obtained by the demonstrative operation of the biogas plant and bio-methane production experiments, a bio-methane production plant that can process waste from 1,000 dairy cows was assumed, and optimization of plant operation was attempted using the linear programming method with maximum environmental friendliness (reduction of greenhouse gas emissions) and economic efficiency (management balance of the plant) as the target functions. The results revealed that plant operation methods varied according to the target of optimization. Environmental friendliness and economic efficiency were in a trade-off relationship with each other, but in the case where the greatest importance was placed on economic efficiency, greenhouse gas emissions were equivalent to that in the case where the greatest importance was placed on environmental friendliness itself. However, the values of economic efficiency were negative in both cases, indicating that it is difficult to make the plant management economically feasible under the current circumstances. To make the plant management balance positive, it is necessary to take measures, such as reduction of plant construction costs and exemption from interest costs. In addition, as a future direction for such regional bio-methane use, a micro grid system with a dispersed power source using bio-methane as raw fuel was presented.
