1s1a: Navigating food waste utilization options to support a circular bioeconomy – A systematic review of existing decision support tools and frameworks

Abstract

Food loss and waste (FLW) represents a significant loss of resources and economic opportunity. Globally, it’s estimated that more than one third of all food produced for human consumption is wasted. In the U.S., most of the food waste ends up in landfills, contributing to 14.1% of the country’s greenhouse gas emissions (GHGs); and approximately 8% of the global GHGs are due to the FLW. Even though several biological FLW diversion cycles exist, it is challenging to determine the most appropriate pathway for a given context with optimal economic, environmental, and societal advantages.
