Expanded polystyrene ban

What is expanded polystyrene (EPS)?

Expanded polystyrene (EPS) is often referred to as Styrofoam™, a trademarked version of the material. However, the correct term for this material is expanded polystyrene.

EPS foam is a lightweight cellular plastic material consisting of small hollow spherical balls that are expanded and processed through a variety of techniques. 

For the legal definition, read the expanded polystyrene definition as it is listed in the law.
 

Problems with expanded polystyrene

Expanded polystyrene materials are difficult to recycle, and it’s expensive. They aren’t accepted in most of Washington’s residential recycling programs and are treated instead as a contaminant. Because they are not readily recyclable, the materials end up in landfills, waste-to-energy facilities, or the environment. 

EPS materials are extremely brittle and break easily into tiny pieces. These small pieces scatter in the wind and contaminate the environment.

Bans on expanded polystyrene begin in 2023 and 2024

Who does the ban apply to?

This ban applies to all manufacturers and distributors of EPS in or into Washington.

Manufacturers include any person, firm, association, partnership, corporation, governmental entity, organization, or joint venture that:

• Produces the products covered under this ban, or
• Imports or distributes these products covered under this ban for sale in or into Washington.

Distributors are any entity that markets, sells, or provides an EPS product as part of a transaction, promotion, or distributions of goods. Examples of distributors include:

• Shipping and packaging establishments
• Small businesses who ship or package goods
• Retail, grocery, and convenience stores
• Restaurants or establishments offering take-out or delivery food or goods
• Temporary stores or vendors, like farmers markets or event vendors
• Health care, correctional, and institutional cafeterias, like schools.

Can my organization use up existing inventory after the ban’s effective date?

No. This law bans the sale and distribution of EPS materials, even if businesses or entities have previously purchased stocks. We encourage entities that currently distribute and sell EPS to transition to a compliant material before or by the effective date of this ban.

How will this law be enforced?

We will respond to non-compliant businesses, institutions, manufacturers, and distributors with education, resources, and technical assistance. Though we intend to provide assistance in gaining compliance whenever possible, repeated and continuous non-compliance may result in up to a $250 fine.

What’s next?

We are providing technical assistance and guidance to manufacturers of the prohibited products. Also, we are working with local governments, producers, distributors, retailers, associations, and nonprofits to develop outreach materials.
