Foam Plastic Products: A View from an Environmental Perspective

Plymouth Foam is committed to operating in a manner which adheres to known, environmentally sound manufacturing practices. The foam products used in our molding operations contain no CFCs, HCFCs or HFCs.

When disposed of, molded foam products remain stable in landfills and pose no threat of groundwater contamination or the production of ozone depleting gasses. They are an extremely clean and efficient fuel source when used in waste-to-energy applications.

Recycling: The Right Thing to Do, Now More Convenient Than Ever

Plymouth Foam is helping to lead an industry wide effort toward increased recycling opportunities. In an effort to minimize the volume of foam materials entering the waste stream, we adhere to a strict source reduction design philosophy. To accommodate increasingly comprehensive recycling initiatives, we are expanding our capacity to process post-consumer EPS. Foam plastics are clean and economical to recycle and can be reprocessed into a wide variety of products.

Shape-molded foam products provide a proven and economical solution for all your packaging and material handling applications. Our ongoing commitment is to provide you with products and service of the highest quality. Your continued satisfaction is our top priority. In planning for the future, as opposed to simply reacting to it, Plymouth Foam is capable of meeting all your shape molded foam requirements.

With a growing network of recycling collection facilities nationwide, disposal of EPS for recycling is now more convenient than ever. To determine the collection facility nearest you, contact the Association of Foam Packaging Recyclers (AFPR) at 1-800-944-8448, or visit

The plastic recycling codes and what they mean:

The Plastics Industry has developed a uniform coding system which identifies the type of resin used in plastic packaging (like bottles, packages, etc.). These "plastic codes" now appear on most forms of plastics, and Plymouth Foam products fit into one of three categories:

The "4" code tells you that the plastic material is Low Density Polyethylene (LDPE). Used predominately in film applications due to its toughness, flexibility and relative transparency, making it popular for use in applications where heat sealing is necessary. The "6" code indicates that the plastic is Polystyrene (PS) or Expanded Polystyrene (EPS). Polystyrene is a versatile plastic that can be rigid or foamed. General purpose polystyrene is clear, hard and brittle. It has a relatively low melting point. Use of the "7" code indicates that the plastic in question is made with a resin other than the six listed above, or is made of more than one resin listed above, and used in a multi-layer combination.
What happens when you recycle Plymouth Foam products?

EPS is 100 percent recyclable, and can be recycled in various ways. The rigid product can be mechanically broken apart, making a lightweight, granular product that has many uses. EPS is also thermally processed to make a resin that is used in a number of valuable products for use in homes, schools and offices.

Additional Environmental benefits to using Plymouth Foam Protective Packaging:
  • No CFCs - EPS has never been made with any CFC, HCFC, or HFC gases. CFCs have been shown to be harmful to the earth's ozone layer.
  • Landfill Safe - EPS is inert and stable. It will not leach out toxic chemicals, heavy metals or create dangerous decomposition gases such as methane, a "greenhouse" type gas. In landfills, EPS helps to keep the ground stable, important when the area is reclaimed for development.
  • Waste to Energy Safe - EPs provides a clean source for WTE inceneration systems. The simple chemical make-up of EPS is carbon and hydrogen, elements found in wood and other organic materials. EPS ash is therefore non-toxic - no unsafe chemicals or heavy metals are produced when burned as a fuel.
