Anyone who’s ever let leftovers languish in the back of the fridge might not be surprised to learn that a whopping third of the food produced each year—about 1.6 billion tons—goes to waste. The Too Good To Go app aims to change that by allowing users to order a “surprise bag” of excess fare from a local restaurant, café, bakery, or grocery store. (Currently the service is pick-up only, in an effort to simplify the process for businesses to participate, and to reduce carbon emissions.) Each bag costs around four to six dollars, and includes contents that are worth about three times that much. Since the Copenhagen-based company launched, in 2016, it has expanded to 15 countries and has saved more than 72 million meals through partnerships with more than 87,000 food establishments. By the end of the year, it plans to be in most major U.S. cities, and later, expand to small towns across North America.
