A framework for a more efficient approach to food waste management

A considerable amount of waste is generated in the food supply chains of both developing and developed countries. In an increasingly resource constrained world, it is imperative to reduce the high environmental, social and economic impacts associated with this type of waste. This necessitates the development and implementation of improved, targeted management practices. This paper discusses the various definitions and categorizations of food waste according to different international organizations, reviews the most up-to-date data on waste generated in the food supply chains as well as its environmental impact and assess the applicability of current waste management options. This analysis provides the basis for the development of a framework for increasing the effectiveness of food waste management practices through structured assessment and better informed selection of waste management methodologies for each food waste category. The usability of this novel framework is discussed.
