Food waste is a major problem in the United States, with about one-third (30%-40%) of the country’s food supply becoming waste, according to USDA 2010 estimates. That’s about 133 billion pounds of food worth $161 billion thrown away, wasting the energy, water, and other resources used to produce it and creating emissions during product transportation and processing.
Bread is the most wasted food product in the U.S., often discarded when it is still edible but simply past peak freshness. Students at the University of Minnesota developed ReToast, a cookie in the shape of toast that is made from at least 30% upcycled food products, such as bread, that would otherwise be wasted.
