Close to 5 million people visit Grand Canyon National Park every year, and 5 million single-use food and drink items are used for minutes, then trucked 145 miles to a landfill. Upstream is replacing that throwaway system with durable reusables that are returned, washed inside the park, and put back into service at 14 takeout and grab-and-go food locations on the South Rim. This isn’t a pilot — it’s a permanent change to how the park runs.
