Seattle has officially become the first major U.S. city to ban restaurants from giving plastic straws and utensils to customers, in an effort to help the environment. As of July 1, restaurants in the Emerald City are barred from providing customers plastic straws, cocktail picks or utensils unless someone specifically requests one. In that case, the customer should be given a compostable option, according to Seattle Public Utilities.

With 5,000 food service providers in the area, Seattle is the first major city in the U.S. to enact such a ban, KIRO-TV reported.

“Plastic pollution is surpassing crisis levels in the world’s oceans, and I’m proud Seattle is leading the way and setting an example for the nation by enacting a plastic straw ban,” Mami Hara, the general manager of Seattle Public Utilities, told KOMO News.

The National Park Service estimates Americans use 500 million straws each day.

The Seattle ban actually began with an ordinance prohibiting one-time-use food-service items in 2008, but the city has allowed exemptions on certain items every year since. For example, polystyrene food packaging was banned in 2009, according to the Seattle Times. But because of the market, plastic utensils and straws have been exempted in Seattle’s ban until now, the newspaper reported.

Restaurants were encouraged to use up existing supplies of plastic straws and utensils before July. If that deadline could not be met, restaurants were asked to check in with Seattle Public Utilities to come up with a different schedule.

Aside from the ban, Seattle food service businesses are also required to use collection bins for compostables and recyclables, a law that went into effect in 2010. Restaurants that do not comply with Seattle’s regulations could face a $250 fine.

Duke Moscrip, founder and CEO of Duke’s Seafood and Chowder, told KIRO his restaurant switched to compostable straws and utensils about three years ago. Then, the products were “30 to 40 percent more expensive,” he said. “Now it’s about 10 percent. But we did it anyway, just because it’s the right thing to do.”

According to the Seattle Times, flexible plastic straws will still be available for customers who need to use them for a medical reason.

Bon Appétit Management Company became the first U.S. food service company earlier this year to ban single-use plastic straws in its eateries, according to Greenpeace.
