Dallas County Single-Use Items: Polystyrene Foam Rules Rules (2026)

Texas Health and Safety Code 361.0961, the Solid Waste Disposal Act preemption clause interpreted by City of Laredo v. Laredo Merchants Association (2018), bars Texas cities and counties from regulating containers and packages, including polystyrene foam. Dallas County has no expanded polystyrene ordinance and is preempted from enacting one. Restaurants, school cafeterias, and grocery stores across Dallas County freely use foam clamshells, cups, and trays. The Texas Restaurant Association cites the ruling whenever local proposals surface. Federal FDA rules still govern food-contact safety of polystyrene. Dallas County HHS and Public Works pursue voluntary recycling and litter education only. Some commercial recyclers accept clean expanded polystyrene from restaurants and offices.
