Simi Valley FAQ
Is expanded polystyrene foodware banned in California?
Yes. SB 54 prohibits sale of expanded polystyrene foodware because it failed to achieve the 25 percent recycling rate by January 2025 required under Public Resources Code 42040-42081.
Can California cities still pass their own foam bans?
Yes. Many cities have stricter local foam bans, and they remain valid. State law sets a floor that cities can exceed but not undermine.
Thousand Oaks FAQ
Are foam cups banned in Thousand Oaks restaurants?
Effectively yes, after January 2025 SB 54 implementation. Producers cannot meet the recycling threshold, so foam foodware is no longer commercially available for restaurant use.
Does Thousand Oaks have its own foam ordinance?
No. Unlike many coastal California cities, Thousand Oaks did not pass a local foam ban before state action. The city relies on CalRecycle's SB 54 enforcement.
