RESIN IDENTIFICATION CODE

The Society of the Plastics Industry introduced the Resin Identification Code (RIC) system in 1988 as a growing number of communities were implementing recycling programs. In order to address the concerns of recyclers across the U.S., the RIC system was designed to make it easier for workers in Materials Recovery and Recycling facilities to sort and separate items according to their resin type. Plastics must be recycled separately, with like materials, in order to preserve the material’s value and enable its reuse in other products after being recycled.
