Hence, the optimal treatment technology needs to be investigated further to solve this critical food waste problem in the urban areas. The first purpose of this study is to investigate the quality and quantity of food waste produced from the household in the Taipei and New Taipei cities. Real food waste samples were collected and analyzed here and the amount of food waste produced from the household were also calculated with various approaches. In addition, the relationship between the food waste amount and some social-economic indicators were examined in this study. The second purpose of this study is to establish the assessment system of food waste treatment technology selection. The Analytic Hierarchy Process (AHP) was used to collect the experts’ opinions to establish the system and to determine the weight of each indicator. Various food waste treatment technologies were evaluated according to this assessment system developed here. Finally, anaerobic digestion with sewage sludge was selected as the optimal food waste treatment technology in the Taipei and New Taipei cities.廚餘再利用分析層級程序法厭氧消化臺北市新北市food waste treatmentAnalytic Hierarchy Processanaerobic digestionTaipei CityNew Taipei City
