Abstract

Material flow analysis is a powerful method for achieving a zero emission society goal. It applies the concepts of industrial ecology to study how materials and energy flow into, throughout, and out of a system. The aim of this study is to estimate the material flow in Yamanashi Prefecture from the viewpoint of time-series using physical distribution census data. The census has been improved through nationwide researches by government organizations every five years. The author calculates the input, output and throughput of material with reference to other statistics, e.g. census of manufactures, input output tables, industrial wastes, final energy consumption and carbon dioxide emission. etc. The mass balance of Yamanashi Prefecture changed from the plus 4, 145 kiloton into the minus 4, 218 kiloton in ten years. Especially, the amount of the mining goods i.e. gravel, sand and stone shipped outside the prefecture has decreased. In addition, this study proposes the factor analysis on a change in the amount of waste referred to as the Kaya Identity Equation. The amount of the waste in 1995 increased because the third industry became active while the second industry stagnated. On the other hand, it was an effect of reduce that the amount of waste in 2000 decreased with a core of the second industry, and was related most the change in the production activity of mining. It is useful to analyze the material flow from the viewpoint of the time-series.
