These days, the shortage of final disposal site is one of the most serious problem in Japan. Waste derived from households is to be disposed by local government and industrial waste by the sectors in the district, while the waste is released due to provide goods and services with various final demand beyond the district. This causes inter-regional environmental dependence. In this study, patterns of interdependent structure of industrial waste induced by final demand is evaluated by using Input-Output Analysis. First, the interrelation between internal and external demand in domestic 8 regions is estimated using waste intensity of each industry. As a result, various sectors' inducement in sludge waste which has great share in final disposal was observed reflecting inter-regional economic transaction. Second, reducing volume and costs of treatment and disposal of the sludge waste were examined taking consideration of polluter's pay principle.
