中国餐饮业食物浪费的资源环境问题综述

近年来食物浪费以及食物浪费的资源环境问题越来越成为全球关注的焦点，尤其是在发展中国家，食物浪费成为威胁食物安全的另一关键因素。尽管如此，在中国，人们仍然对食物浪费缺乏认识，尤其是餐饮业中消费者的食物浪费。因此，基于国内主流媒体报道的大量餐饮业食物浪费的案例数据资料，本研究针对餐饮业中的食物浪费做了系统的阐述。针对餐饮业食物浪费的初步估计，本研究揭示了我国餐饮业食物浪费的严重性。通过分析国际上大量食物浪费的相关文献资料，本研究具体阐述了食物浪费的资源环境代价。最后，本研究基于生命周期评价方法提出了针对餐饮业食物浪费及其资源环境效应研究的概念框架，以便更有效地减少食物浪费。

An Overview of the Resources and Environmental Issues from Wasted Food in Urban Catering across China

There is growing global concern over food waste and its impacts on resources, environmental issues and food security, especially in developing countries. However, knowledge of food waste, in particular, the food wasted by consumers in restaurants, is entirely inadequate in China. Here, based on media reports and documents about food waste we provide an overview of food wasted by consumers in restaurants in China. We roughly estimated total food waste in order to uncover the seriousness of this large issue. We collected international literature referring to food waste and provided a detailed explanation of the resources and environmental costs associated with food waste. Ultimately we propose a conceptual diagram on research into catering food waste by consumers to evaluate resources and environmental costs based on life cycle assessment in China. This work will stimulate interdisciplinary research in this field.
