Abstract

An evaluation method of environmental loads that occurs with the phase of recycle is behind with the evaluation methods for the other phase. This is caused by that a grasp of the actual situation of a recycle industry is difficult with that a process of recycling is complicated. Therefore we suggest the evaluation method for calculating the environmental impact on the phase of recycle. The evaluation method has three new concepts that are “Agreement an evaluation range around the phase of recycle and the phase of disposal”, “Taking the transportation distance and the way of transportation into consideration”, “Taking the waste reduction ratio around a transportation into consideration”. As we evaluate an influence to an environment at a process of PSP TRAY recycling by this evaluation method, we obtained a result that applies. If we evaluate it while being careful of this point, we can evaluate social system such as waste collection, processing-disposal and recycle in aspect of environmental impact.
