The Disposable Food Service Ware and Polystyrene Foam Model Ordinance was developed by Zero Waste Sonoma staff in 2018, and approved by the Agency Board of Directors. City Councils were presented the ordinance in 2019, 2020, and 2021. Most jurisdictions opted to delay ordinance enforcement until 2022, due to COVID-19. In 2024, Zero Waste Sonoma will be conducting a technical assistance project to provide education and outreach to many of the impacted businesses throughout Sonoma County.
