摘要: 在垃圾分类开展及“无废城市”试点建设的背景下,对餐厨垃圾管理现状、存在问题进行系统梳理和深入分析。采用政府统计数据采集和中英文文献数据提取等方法,估算2017年我国产生餐厨垃圾约1.58×108 t,其中餐饮垃圾约0.63×108 t。结果表明各地区餐厨垃圾产生量、理化特性、处理能力和水平等存在时空差异。我国餐厨垃圾资源化利用能力与水平虽得到明显发展,但仍存在源头减量重视不足、处理能力缺口明显、水平效率有待提升、绩效评估缺乏方法等问题。建议各地区应因地制宜,结合垃圾分类和“无废城市”建设,不断提升餐厨垃圾减量化和资源化水平,弥补分类处理缺口。政府、企事业单位、居民等多方共同参与餐厨垃圾全过程管理。通过规范评估主流处理工艺和监管餐厨垃圾处理项目实际运行效果,建立多维度评价方法学体系,实现餐厨垃圾管理全过程和全周期环境—资源—成本等多维度效益的定量分析研究,为未来政府和行业有效决策提供科学依据。

Abstract: Under the background of waste classification and “zero waste city” pilot construction in China, the current management status and the existing problems were systematically sorted out and deeply analyzed. Through the collection of government statistical data and the extraction of Chinese and English literature data, it was estimated that the generation of food waste in China in 2017 was approximately 158 million tons, which included 63 million tons of restaurant food waste. The results showed that temporal and spatial discrepancies existed in food waste generation, characteristics, and treatment capability across different regions. Although the utilization of food waste in China has been significantly developed, a few problems still need to be solved, such as insufficient attention attached to source reduction, deficiency in treatment capacity, low efficiency in treatment technologies, lack of performance evaluation methods, etc. It was suggested that all regions should combine the waste classification and the “zero waste” construction according to local conditions, improve the reduction and resource utilization of food waste and make up the gap in treatment capacity continually. The government, enterprises and institutions, residents and other parties should jointly participate in the whole process of food waste management. By standardizing and evaluating the performance of mainstream technologies, and supervising the actual operation of food waste treatment projects, a multi-dimensional evaluation methodology should be established to realize the quantitative analysis of environment, resources and cost of food waste management from a life cycle perspective, so as to provide scientific basis for effective decision-making of the government and the industry in the future.
