This paper analyses the food waste collection and transportation (C&T) system in a pilot project in Suzhou by using a novel performance evaluation method. The method employed to conduct this analysis involves a unified performance evaluation index containing qualitative and quantitative indicators applied to data from Suzhou City. Two major inefficiencies were identified: a) low system efficiency due to insufficient processing capacity of commercial food waste facilities; and b) low waste resource utilization due to low efficiency of manual sorting. The performance evaluation indicated that the pilot project collection system's strong points included strong economics, low environmental impact and low social impact. This study also shows that Suzhou's integrated system has developed a comprehensive body of laws and clarified regulatory responsibilities for each of the various government departments to solve the problems of commercial food waste management. Based on Suzhou's experience, perspectives and lessons can be drawn for other cities and areas where food waste management systems are in the planning stage, or are encountering operational problems.
本文运用一种新颖的绩效评估方法，对苏州一个试点项目中的食物垃圾收集与运输（C&T）系统进行了分析。开展此项分析所采用的方法涉及一个统一的绩效评估指标，该指标包含定性和定量指标，并应用于来自苏州市的数据。识别出了两个主要低效问题：a）由于商业食物垃圾处理设施处理能力不足导致系统效率低下；b）由于人工分拣效率低导致垃圾资源利用率低。绩效评估表明，试点项目收集系统的优点包括经济性强、环境影响小和社会影响小。本研究还表明，苏州的综合系统已制定了一套全面的法律，并明确了各政府部门解决商业食物垃圾管理问题的监管职责。基于苏州的经验，可以为其他处于食物垃圾管理系统规划阶段或遇到运营问题的城市和地区提供思路和借鉴。
