Sonoma County Jurisdictions are Taking Steps to Ban Styrofoam and Disposable Food Ware

Sebastopol leads the way for Sonoma County Cities and Towns to adopt a Disposable Food Service Ware and Polystyrene Foam Ban

The Disposable Food Service Ware and Polystyrene Foam Model Ordinance was developed by Zero Waste Sonoma staff in 2018. City Councils from many jurisdictions were presented the ordinance in 2019 and 2020, and some are expected to delay ordinance readings until 2021 due to COVID-19. For those jurisdictions that have adopted the ordinance, enforcement will begin as scheduled, but understanding the significant impacts of the pandemic particularly to restaurants, the focus will be on technical assistance first before punitive action is taken. Following adoption, businesses will have a grace period to sell or use their existing stock of disposable food service ware and polystyrene foam products.

More information and details about the ordinance can be found on this webpage.
