Iowa Code §455B.302 also preempts local bans on polystyrene foam food containers; Des Moines cannot prohibit Styrofoam takeout boxes or cups regardless of environmental concerns.
The same auxiliary-container preemption that bars plastic bag rules (Iowa Code §455B.302) extends to expanded polystyrene foam containers. Cities like New York, Seattle, and Berkeley have banned foam takeout containers, but Des Moines has no legal authority to enact such a ban under current Iowa law. Restaurants and retailers in Des Moines may voluntarily switch to compostable or paper alternatives, and many do as part of sustainability commitments. The Des Moines Climate Action Plan (2024) encourages voluntary reduction, but cannot mandate it. Foam recycling remains limited because Metro Waste Authority does not accept foam in curbside recycling.
No local violations because the city cannot regulate foam containers; littering laws still apply to discarded foam under Ch. 78 Solid Waste.
