Abstract

The local authorities are worried about the increase in waste generation. Therefore, our work was geared up towords a guideline for getting waste reduction and the promotion of waste recycling in all areas. At first, we surveyed the waste generation rate per capita and the resource recovery rate per capita in all elementary school districts, and mapped out the data. The characteristics of waste generation in all areas as clarified through our survey are summarized as follows: The generation rates of incombustible wastes in residential districts, commercial areas and resort areas were high. The resource recovery rates in the residential districts were high and the generation rates of incombustible waste were low. The highest resource recovery rate accounted for 30% of the incombustible waste generation rate. The generation rates of incombustible waste in the commercial district was 1.7 times higher than that in the residential district. From the above mentioned results, it can be suggested that the minimization of incombustible waste generation can be achieved by the promotion of resource recovery, while the increase of it is caused by the contamination of domestic incombustible waste by commercial waste.

Key words: domestic incombustible waste, resource recovery rate, mapping, minimization, solid waste management
