HB 477 Montana House · 2025 Regular Session

Phase out polystyrene single use food containers (with exceptions)

House Bill 477 aimed to phase out the use of expanded polystyrene foam, commonly known as Styrofoam, in food-related businesses. Beginning in 2028, it would have prohibited restaurants and food establishments from serving food or beverages in these containers for on-premises consumption. By 2029, this prohibition would extend to packaging prepared food by restaurants, hotels, and resorts, and by 2030, food packagers would be restricted from using them. Businesses could apply to the Department of Environmental Quality for exemptions if compliance caused undue hardship or if no acceptable alternatives were available, with the department authorized to charge a fee for such applications.
