When we think of sustainable practices and green efforts, recycling and reducing usage of materials and power sources are among the first things that spring to mind. However, there is one waste problem that is commonly overlooked. Two billion dollars a year: the amount of money that American consumers, businesses and farms spend on growing, transporting and disposing of food that is never eaten. This equates to over 50 million tons of food that is sent to landfills annually—over 40% of all food produced goes to waste. This food is the single largest component of U.S. municipal solid waste and accounts for a large portion of the U.S. methane emissions.
