Overview of Composting and Plastic Bans

The City aligns local obligations with California organics diversion mandates and restrictions on certain single-use plastic items. Businesses that generate food or green waste must segregate organics for collection under state and local programs, and many common disposable plastics are prohibited or restricted in retail and food-service settings.
