Milwaukee FAQ
Can Milwaukee restaurants stop using foam clamshells?
Yes voluntarily, but the city cannot require it. State preemption blocks any local mandate, so restaurant choice depends on cost and customer preference.
Does Milwaukee city government use foam?
City facilities have moved toward non-foam alternatives under voluntary sustainability procurement, but this applies only to city operations, not private businesses.
