As much as one-third of the food intentionally grown for human consumption is never consumed and is therefore wasted, with significant environmental, social and economic ramifications. An increasing number of publications in this area currently consider different aspects of this critical issue, and generally focus on proactive approaches to reduce food waste, or reactive solutions for more efficient waste management. In this context, this paper takes a holistic approach with the aim of achieving a better understanding of the different types of food waste, and using this knowledge to support informed decisions for more sustainable management of food waste. With this aim, existing food waste categorizations are reviewed and their usefulness are analysed. A systematic methodology to identify types of food waste through a nine-stage categorization is used in conjunction with a version of the waste hierarchy applied to food products. For each type of food waste characterized, a set of waste management alternatives are suggested in order to minimize environmental impacts and maximize social and economic benefits. This decision-support process is demonstrated for two case studies from the UK food manufacturing sector. As a result, types of food waste which could be managed in a more sustainable manner are identified and recommendations are given. The applicability of the categorisation process for industrial food waste management is discussed.
有意种植供人类食用的食物中，多达三分之一从未被食用，因此被浪费掉了，这带来了重大的环境、社会和经济影响。目前，该领域越来越多的出版物探讨了这个关键问题的不同方面，并且通常侧重于减少食物浪费的积极方法，或者提高废物管理效率的应对措施。在此背景下，本文采取整体方法，旨在更好地理解不同类型的食物浪费，并利用这些知识为更可持续的食物浪费管理提供明智决策依据。为此，对现有的食物浪费分类进行了回顾，并分析了其有用性。通过一个九阶段分类系统识别食物浪费类型的系统方法，与应用于食品的废物层次结构版本相结合。针对每种确定特征的食物浪费类型，提出了一系列废物管理方案，以尽量减少环境影响并最大化社会和经济效益。该决策支持过程通过英国食品制造业的两个案例研究进行了演示。结果，确定了可以以更可持续方式管理的食物浪费类型，并给出了建议。讨论了分类过程在工业食物浪费管理中的适用性。
