If a documentary about global food waste and its remedies doesn’t sound mouthwatering, think again, for this is a rousing good story of mind-boggling foodie innovations, high-tech initiatives pioneering in Europe and Asia, and unusual gastronomic delights that include a British beer brewed from stale bread and more than 50 varieties of designer pork from happy Japanese pigs fed on diets of specially targeted food waste. The film’s executive producer, chef Anthony Bourdain, a leader in creative solutions to a worldwide dilemma that encompasses everything from agricultural overrun to home kitchen scraps, joins a coterie of chefs and food critics including Dan Barber, Mario Batali, Danny Bowien, and Massimo Bottura, to provide a shocking, enlightening, and entertaining look at the problem and an abundance of innovative solutions.
