碩士 === 國立臺灣大學 === 環境工程學研究所 === 95 === The subjects of this study are the material flows of general waste treatment in Taipei City, Taipei County and Taoyuan County which account for around 36% of total population and garbage production of Taiwan. By analyzing the procedures of general waste treatment in the three major city/counties of northern Taiwan, material and energy flow directions in the whole treat procedure are described. In combination with the concept of recycling-based society, this study also assess if the three city/county meet the developing trend of a recycling-based society, in aspects of waste reduction, reusing, recycling, energy renewal and proper treatment. The study results suggest that in respect of material flow analysis, Taoyuan County showed the best performance that 92.57% of garbages were turned into energy by incineration treatment. In respect of the energy flow analysis, the study results suggest that all the main productivities of the general waste treatment in all these three city/counties were the recovery of heat produced by incineration treatments, wherein the heat recovery productivity of Taipei County was the highest, followed by Taoyuan County. In respect of the establishment of recycling based society, it was assessed by the stage of recycling treatment. According to the index of material recycling, Taipei City performed the best. In the promotion for kitchen waste recycling, all these three city/counties, no matter by making compost or feeding pigs, not only obtained economical benefits directly, but also decreased lots of processing costs on the incineration treatment and efficiently lower the dioxin pollution which may caused by the incineration treatment to kitchen wastes. As a whole, comparing the strategies of waste treatment, in the view of the establishment of a recycling-based society, of these three city/counties, it was Taipei City that performed better. The main reason is that the way of waste treatment in Taipei City was mainly recycling thus conformed to the concept of the establishment of a recycling-based society. In respect of the index of the establishment of a recycling-based society, moreover, procedures of waste treatment were not comprehensively considered in this study, continuing studies can construct representative index system for use.
