11 Nov 2014 --- Food waste has become a serious problem in the United States and other countries. Approximately 34 million tons of food waste is deposited in landfills each year in the United States alone (EPA, 2014). The U.S. Environmental Protection Agency has recognized the use of food waste as animal feed as one of the best means to add value to food waste, while reducing landfill costs and greenhouse gas emissions, and at the same time improving food security.
