How to dispose of Styrofoam (Polystyrene) in California

California rules

California restricts EPS food service ware under SB 54. Check current CalRecycle guidance and local disposal rules; a sale restriction does not establish recycling acceptance.

General steps

1. Check if your local recycling program accepts expanded polystyrene (EPS) — most curbside programs do NOT.
2. Search for Styrofoam drop-off locations at recycling centers or shipping stores.
3. Clean food-contaminated Styrofoam cannot be recycled — place in regular trash.
4. Packing peanuts can be returned to UPS stores and shipping centers for reuse.
5. Break into smaller pieces before trashing to save space.
