San Francisco International Airport (SFO) announced that it’s banning the sale of plastic water bottles on its premises. It is part of the airport’s goal of becoming the world’s first zero-waste airport by 2021 and will go into effect on Aug. 20. The ban addresses “one of the major sources of waste generated at the Airport,” SFO said in its announcement. Vendors will need to offer reusable bottle options, such as metal or glass containers, or single-use compostable cups for water.
The San Francisco airport has long encouraged passengers to bring their own reusable water bottles to the airport, and it made news in 2011 for installing water bottle refill stations in a newly renovated terminal. There are now nearly 100 of those stations throughout the airport, up from just 36 in 2016.
