食物浪费占工业化国家废物流的很大一部分，造成生态破坏和营养损失。本研究以系统方法为指导，对 1998 年至 1999 年美国一个县的食物浪费进行了量化。出版物和个人访谈被用来量化食品生产、加工、分配和消费中的浪费。该社区粮食系统每年产生约 10,205 吨食物垃圾。在所有食物垃圾中，生产垃圾占 20%，加工垃圾占 1%，分销垃圾占 19%，而 60% 的食物垃圾是由消费者产生的。不到三分之一 (28%) 的食物垃圾总量通过堆肥 (25%) 和食物捐赠 (3%) 进行回收，超过 7,000 吨 (72%) 被填埋。超过88亿大卡的食物被浪费，足够该县居民1.5个月的食物。本案例研究提供了量化和比较整个社区食品系统中食物浪费的程序示例。
Food waste comprises a significant portion of the waste stream in industrialized countries, contributing to ecological damages and nutritional losses. Guided by a systems approach, this study quantified food waste in one U.S. County in 1998-1999. Publications and personal interviews were used to quantify waste from food production, processing, distribution, and consumption. Approximately 10,205 tons of food waste was generated annually in this community food system. Of all food waste, production waste comprised 20%, processing 1%, distribution 19%, and 60% of food waste was generated by consumers. Less than one-third (28%) of total food waste was recovered via composting (25%) and food donations (3%), and over 7,000 tons (72%) were landfilled. More than 8.8 billion kilocalories of food were wasted, enough to feed county residents for 1.5 months. This case study offers an example of procedures to quantify and compare food waste across a whole community food system.
