Abstract
Components and quantities of commericial waste generated vary according to the source and the nature of the commercial activity. In this study business establishments are classified into 11 groups according to business activity. A simple method for estimation of waste generation, recycling, and its composition for each group was then developed. Unit waste amounts per worker are determined for each group by modifying the exising results obtained already through a survey carried out by the city of Sapporo. By multiplying the number of workers, which is easily accessible through general statistics on business activity, waste stream is then calculated. The unit values used in this study and estimated amount or composition were confirmed by comparing these results with those of other studies. The accuracy of the model was checked by the estimated disposal amount for 104 cities. As an example to show the usefulness of the model, an application for a recycling plan is also demonstrated.
