Malt-O-Meal knows how to deliver a timely wakeup call. Through its new Bag The Box movement, the cereal maker wants America to digest some jaw-dropping figures: It takes 345 million pounds of paperboard to make a year’s supply of cereal boxes. That’s equivalent to the weight of 734,747 jumbo jets. And every year, the United States produces 2.3 billion cereal boxes. That’s enough cardboard to build almost three great pyramids. And there’s no reason for redundant packaging that comes with a bag of cereal inside of a box, says the company that packages most of its ready-to-eat cereals in resealable bags.
