【摘要】：餐厨垃圾是城市生活垃圾的重要组分,其末端为主的处理方式造成占用土地、环境污染、资源浪费等环境负荷日益严重,其外部性令政府不堪重负。文章基于绿色供应链生命周期管理的思想,对城市垃圾减量过程管理的研究系统进行重新界定并研究食品垃圾减量管理模式。构建了以食品物质流过程环节及其主体感知和行为的影响因素构成的垃圾减量分析和管理框架模型,提出并定义了行为主体对垃圾减量管理的绿色感知强度指数和减量行为绿色强度指数,以北京市餐厨垃圾现状调研数据为例,实证分析垃圾减量绿色感知强度和主体绿色行为之间的互动关系及规律,以此揭示在食品物质流过程从外部管理、基础设施等手段内化为主体的资源减量认知、态度和行为的内在规律,为垃圾减物质化管理及其模式的形成提供科学依据。研究发现:(1)食品物质流垃圾减量管理系统呈现两端环节的净菜和分类行为减量管理薄弱的特点,其中社区居民垃圾分类问题尤为严重,需探讨完善系统化的过程资源减量化管理模式;(2)深层次的环境认知和环保自觉意识以及垃圾减量化行为约束的外部机制薄弱,因此呈现出较高的垃圾分类认识与较低下绿色自觉行为之间存在显著缺口的现象,深化普及绿色价值观和规范行为是推动垃圾减量管理的重点举措;(3)厨余垃圾减量系统是消费、排放、回收以及管理模式协同联动的有机整体,需促进消费、经营、管理模式协同的绿色转变,并建立资源和垃圾减量化管理的短期、长期激励关联机制,逐步建立城市垃圾减量化管理模式。
[Abstract]:Kitchen garbage is an important component of municipal domestic waste. The main disposal method at the end of it causes serious environmental load such as occupation of land, environmental pollution, waste of resources and so on. The externality of the waste is unbearable to the government. Based on the idea of life cycle management of green supply chain, this paper redefines the research system of urban waste reduction process management and studies the mode of food waste reduction management. A model of MSW reduction analysis and management framework is constructed, which is composed of the food material flow process and the factors affecting the perception and behavior of the main body. The green perceptual intensity index and the green intensity index of decrement behavior of MSW are proposed and defined. The investigation data of the status quo of the food waste in Beijing are taken as an example. This paper empirically analyzes the interactive relationship between the green perceived intensity of garbage reduction and the green behavior of the main body, thus revealing the cognition of resource reduction as the main body in the process of food material flow from the external management, infrastructure and other means. The internal law of attitude and behavior provides scientific basis for waste dematerialization management and its mode formation. The study found that the waste reduction management system for the flow of food substances showed the characteristics of weak reduction management of net dishes and classified behaviors at both ends of the chain, especially the problem of garbage classification for community residents. It is necessary to explore how to improve the systematic management model of process resource reduction. (2) the deep level of environmental awareness and awareness of environmental protection, as well as the external mechanism of waste reduction behavior constraints are weak. Therefore, there is a significant gap between higher awareness of garbage classification and lower green conscious behavior. Deepening the popularization of green values and standardizing behavior is a key measure to promote waste reduction management.) the kitchen waste reduction system is consumption. The organic whole of emission, recovery and management mode, which need to promote the green transformation of consumption, management and management mode, and establish the short-term and long-term incentive linkage mechanism for reducing the management of resources and garbage. Gradually establish the urban waste reduction management model.
