Abstract

LCA (life cycle assessment) is an environmental evaluation tool for a product system based on life cycle thinking. After ISO14040 established in 1997, seven years have passed, and LCA has begun to be use in business. However, it is difficult to evaluate an open-loop recycling system or a system which produces several kinds of products. It seems to be a cause that a conventional LCA is an evaluation tool for a product system with single function unit, In this study, a new LCA method for a system with multi-function units was developed, which was based on matrix LCA method.
