In recent years, major fast food chains have actually aimed to reduce disposable packaging.And now, Burger King is joining that club; they plan to rest reusable cups and containers beginning next year.The test run will begin sometime in 2021 at locations in New York City, Portland, and Tokyo.The pilot program will feature a cup for hot and cold beverages, and a box similar to the kind burgers come in.The all-brown packaging has a sort of a 1970s vibe in its design.And they can be returned to receptacles to be re-used.Burger KIng is also collaborating with Kraft-Heinz to share resources and insights to further sustainability
