Abstract

In this paper, we studied the present situation of refuse recycling in Ube City and analyze the collection cost by scenario-analyses. Resource recovery has been done mainly by the volunteer works of children circles and so forth. However, the activity has been suppressed by the low price of resources nowadays. Almost 1/3 of community circles has not been involved in the volunteer works for refuse recycling. In new residential areas with many children, the frequency of the volunteer works and the recovery rate of resources tend to be high. As the result of scenario-analyses, the collection cost of refuse recycling by the municipality amounts to be 4 times of the cost for recycling by volunteer works. In case of newspaper refuse, the collection by municipality was estimated to be feasible only if the recovery rate was higher than 70%, otherwise it is more advantageous for the municipality to collect and incinerate the newspaper refuse together with garbage.
