Environmental Impact Evaluation of Zero Emission System: A case study of Cement Production

Various zero emission systems have been recently constructing in Japan as a proactive approach for creation of a recycle-oriented society. It is indispensable to evaluate the environmental impact quantitatively to promote these zero emission businesses. Municipal waste treatment systems with two different scenarios of landfill and recycling in cement production were used as case study. Overall environmental impact of these scenarios was quantitatively evaluated by using life cycle impact assessment method namely "LIME" in this research. The results indicated that the use of municipal wastes in cement production could reduce the overall life cycle impacts
