To realize the biomass energy systems which is characterized as one of the pillars of the sustainable society is greatly significant, because of the multiple advantageous effects, such as global warming countermeasures, rising self-sufficiency ratio in the energy supply, national land conservation, regional development and biomass industry structural improvement. In this paper, we designed the hybrid systems of DME and electric power generation using biomass for a rural area and evaluated the system from the viewpoint of LCA and economics. The analysis shows that the system using only barks as fuel cannot economically viable. The system using both barks and plastic wastes as fuel reduces CO_2 emissions in comparison with the present system, and is also economically possible because of the inverse onerous contract of the plastic wastes. The plant scale, distance of conveyance of ingredient, and circulation income of energy do not have large effects on the economics of the system.
