The ordinance includes a ban of expanded polystyrene (aka Styrofoam) containers at restaurants along with a requirement for restaurants to only offer straws upon request and utensils for takeout orders only upon request. The ordinance also includes a retail ban on coolers, beach toys, egg cartons, food service ware (plates, cups, etc), or food trays made, in whole or in part, from polystyrene foam that is not wholly encapsulated or encased within a non-polystyrene foam material. (Those flimsy white foam coolers that easily break into smaller pieces are out but the durable Igloo-type coolers are still allowed.)
The Surfrider Foundation San Diego County Chapter has worked with a coalition of groups to raise public support, get endorsements from dozens of neighborhood councils, host community rallies, and rally at the various City Council meetings along the way.
Plastics are the most common marine litter worldwide. They don't biodegrade in our lifetimes; instead, they break up into smaller particles that persist in the ocean, release toxins, and enter our food chain through fish and other marine life. Polystyrene in particular poses human health risks, and is a known animal carcinogen and is reasonably anticipated to be a human carcinogen. Styrene is derived from petroleum or natural gas and the process of making EPS foam has an impact on climate change through increased greenhouse emissions.
Like other single-use plastics, EPS is a primary contributor to litter in San Diego because of its ability to fragment into smaller pieces. In San Diego County, volunteers removed 20,883 pieces of polystyrene from our beaches in 2017. Additionally, plastic straws are one of the most common items found during beach clean-ups and are detrimental to marine wildlife.
