Abstract
Waste treatment creates relations of interdependence between waste treatment sections and production sections. The Waste Input-Output table（WIO）analyzes the relations of such interdependence. Considering the product goods from the construction industry, there is a time lag between production and disposal. However, a static model like WIO is unsuitable for the analysis
of durables with several years of life. The purpose of this study is to dynamically extend Waste Input-Output Analysis.

Key words: Waste Input Output Analysis, dynamics, fixed capital stock, durables
