US wastes 40% of edible food per year
"The United States wastes about 40 percent of its edible food each year. Food is wasted at each stage along its journey-from creation and distribution through to restaurants and cafeterias. In fact, more food reaches landfills and incinerators than any other type of waste we produce, with household food waste one key contributor."
