The food Hierarchy is depicted in this Food Hierarchy Chart. This focuses on providing the most environmentally friendly waste disposal option. 'Prevention' is thus at the top of the inverted pyramid as the best option, and 'disposal' is at the bottom as the least good option. The Food Hierarchy Chart's guiding principle is to keep food products at the highest possible tier, redefining waste as a potential resource rather than an unwanted burden. However, a growing international agreement is that a food use hierarchy is required to shift the focus to reusing food, first for human consumption and then as animal feed, to keep food in the food chain for as long as possible.
