ABSTRACT
To establish a household appliance disposal and recycling strategy, it is required to accurately estimate changes in the types and quantities of end-of-life appliances that will be disposed from homes and offices in the present through the future. Note that periods of time from their procurement (demand occurrence) to disposal are not constant, and future demands for every product cannot be predetermined. In countries that have a high population and have shown significant improvement in living standard levels corresponding with economic development, quantities of disposed products are expected to increase significantly in the future as demands for products continue to increase. However, the aforementioned conditions prevent us from accurately predicting future quantities of disposed products by only observing the statistical data obtained thus far. Therefore, we need an effective tool that numerically estimates the future waste quantities (i.e., quantities of end-of-life products) by modeling the product lifetime, including the occurrence of demand, a period of use, and product disposal.
