The new rule will apply to airport restaurants, cafes and vending machines. Travelers will need to buy refillable aluminum or glass bottles if they do not bring their own, AP reports.
The airport is following an ordinance approved in 2014 banning the sale of plastic water bottles on city-owned property, according to AP. SFO retailers already are required to provide only compostable single-use to-go containers, condiment packets, straws and utensils.
The airport also published a Zero Waste Plan last year. SFO reports that it hopes to become the “world’s first zero waste airport by 2021.” The airport’s Zero Waste Plan outlines measures the SFO needs to take to achieve zero waste by 2021 and work toward becoming a Closed-Loop Circular Campus in the years that follow to control material inputs to maximize recycling and recovery and minimize waste materials generated onsite.
