Description

In order to establish a material recycling oriented society to achieve zero emission, analyzing current regional material flow is needed. The analysis is an important key to optimize regional material cycle to make efficiency of resource consumption rise and to minimize environmental load. Various methods in estimating industrial material balances have been tried However, those methods are not very realistic because they require a lot of time and effort. In our study, we developed a simplified method when analyzing regionally, the current material flow using an Input-Output table, and we applied this method to the industries in Aichi prefecture, Japan Because the input output table shows cash flow among industries, making a proper parameter could convert cash flow to material flow. This method is used to estimate input, output and waste generation of all industries. Results show that this method also estimates waste generation and waste ice of each industry. Then we discuss some measures to encourage the recycling of waste.
