Block Foam

Block foam can be recycled at any of our Clark County transfer stations: West Vancouver Materials Recovery Center, Central Transfer & Recycling Center, and Washougal Transfer Station.

Block foam is made of expanded polystyrene, commonly known as Styrofoam™. This material cannot be placed in standard curbside recycle carts or containers. Doing so causes the small, lightweight material to break into small pieces, rendering the material unrecyclable. The small fragments can also contaminate other recyclable materials and litter our streets and environment. So it is important to recycle block foam properly.

Accepted Materials

Polystyrene (#6): We accept large pieces of clean, white polystyrene foam that was used as packaging material. This material is stiff and breaks with a snap. We do not accept packing peanuts, or food service products like egg cartons or trays.

At this time, we are not accepting other types of block foam, including polypropylene (#5) or polyethylene (#4). These foams may be white or colorful, and their texture may be spongy or feel similar to polystyrene foam. Be sure to look for the number 6 on the packaging to be sure that your block foam can be recycled.

We do not accept squishy foam such as cushions or insulation. Foam should be clean of any food residue, stickers, tape, laminate, paper, cardboard or other materials. We do not accept packing peanuts or popcorn. We do not accept food service products such as foam egg cartons or foam trays from meat and seafood.


Bring your block foam to a transfer station for recycling. At the transfer station, you will need to separate your foam into two categories: (1) polystyrene, and (2) polypropylene and polyethylene. If you have large volumes of block foam, such as 5 yards or more, please call the transfer station for instructions.


Residents do not pay to recycle block foam.

Block foam produced by businesses is charged at a rate of $5 per yard. If your business creates large volumes of block foam, such as 15 yards or more, you may be interested in a temporary or permanent container service. Please contact our customer service department for rates and more information.
