About Foam Recycling

The process to recycle foam is like that of other recyclables. In the case of foam products, a special compactor – called a “densifier” – may be used in the processing of the material. Foam products are over 90% air, so densifying it allows the material to be transported more cost-effectively. To give you an example, a 48-foot truckload of baled foam polystyrene weighs only around 16,000 pounds, whereas a truckload of densified foam polystyrene weighs 40,000 pounds.

Innovative alternatives are being developed and deployed that are categorized as chemical recycling (vs. mechanical recycling). This will take the plastic resin back to its base state – in the case of foam PS, back to a styrene monomer. With chemical recycling, increased organic contamination will only impact the amount of foam for recovery (yield), but will not impact the recyclability of the plastic.

Foam Recycling Coalition Grant Program

Funding Source: Funding for the grant program comes from contributions from members of the Foam Recycling Coalition, a special interest group of the Foodservice Packaging Institute.

Grant Amounts: Funding amounts will be made on a case-by-case basis and will be dependent on equipment needs. The maximum amount per grant is $50,000.

Cash Match: No cash match is required, but additional costs by the grantee may be incurred for related items such as site preparation, provision of conveying system and electrical infrastructure, freight, and other installation costs.

The AAAAI Distinguished Layperson Award recognizes non-medical citizens for their significant contributions to the field of allergy, asthma, and immunology.

This acknowledgment reflects the growing importance of citizen volunteers in advancing the specialty and improving patient care.
