(STACKER) — Americans waste about 40% of the food we purchase, statistically equivalent to an average consumer buying five bags of groceries and immediately dumping two bags in the trash upon leaving the store.

Read on to find out the industrial and business sectors that contribute most to excess food waste. The information was compiled based on data from the 2018 Wasted Food Report from the Environmental Protection Agency, released in the fall of 2020. Although the COVID-19 pandemic impacted each of these sectors’ contributions to food waste, this data examines how these industries contribute to food waste when operating at normal capacity.
