The Problem With Styrofoam for Packaging
Polystyrene packaging, commonly known as Styrofoam, has significant environmental drawbacks due to its production, use, and disposal.
Firstly, it is non-biodegradable, taking hundreds of years to break down in landfills. This persistence contributes to the rapid filling of landfill space, where polystyrene accounts for a substantial portion of waste.
Additionally, it is rarely recycled because of its lightweight nature and the high cost of processing. As a result, large quantities end up as litter in urban areas and waterways. In marine environments, polystyrene fragments into microplastics that wildlife ingests, causing choking, starvation, and toxic exposure; these microplastics can also enter the food chain, posing risks to human health.
The production process of polystyrene further exacerbates its environmental impact. It involves using toxic chemicals such as benzene and styrene, which harm human health and contribute to air and water pollution.
The manufacturing process is energy-intensive, releasing greenhouse gases and hydrofluorocarbons (HFCs) that damage the ozone layer and contribute to climate change. Moreover, polystyrene releases additional pollutants into the environment when disposed of through incineration or degradation in landfills. These combined factors make polystyrene one of the most environmentally damaging materials used in packaging.
As part of ongoing attempts to reduce the damage caused by plastics in packaging, a number of states have enacted rules to ban or limit the use of Styrofoam.
Which States Have Styrofoam Bans?
California: A full ban on most polystyrene foam food containers began January 1, 2025, under SB 54, targeting clamshell containers, cups, and trays.
Colorado: Ban on ready-to-eat food containers (including plates, cups, and trays) took effect January 1, 2024.
Delaware: Food service packaging ban starts January 1, 2025, excluding coolers for raw meat/seafood.
Maine: Implemented in 2021, covering retail food containers; expanded to include foam egg cartons and raw meat trays in 2025.
Maryland: First statewide ban enacted in 2020, prohibiting foam food containers and egg cartons (with exemptions for seafood coolers).
New Jersey: Ban effective May 2022, including food containers, cutlery, and foam egg cartons.
New York: Ban started January 2022, covering food containers and packing peanuts.
Oregon: Prohibits single-use polystyrene coolers and food containers starting January 1, 2025.
Rhode Island: Disposable polystyrene serviceware ban begins January 1, 2025.
Vermont: Implemented in 2021, targeting food containers and foam egg cartons.
Virginia: Large businesses will be fully banned from using polystyrene food containers in July 2025, and smaller businesses will follow in 2026.
Washington: Foodservice products banned starting June 2024, following a 2023 prohibition on packing peanuts.
Why Not a National Ban on Styrofoam Packaging?
There is currently a bill in Congress, The Farewell to Foam Act of 2023, a proposed federal bill introduced by Senator Chris Van Hollen (D-MD) and Representative Lloyd Doggett (D-TX) in December 2023.
The legislation aims to phase out the sale and distribution of single-use expanded polystyrene (EPS) products, including food containers, loose-fill packaging (e.g., packing peanuts), and disposable coolers, by January 2026. The bill is designed to address the environmental and health harms associated with plastic foam.
As you’d expect, the bill faces opposition from industry lobbyist groups like the American Chemistry Council, and its likelihood of becoming law is questionable.
