Resin Identification Codes

The Resin Identification Code was an industry invention that was carried through many state legislatures in the late 1980s during a time of increased attention on the proliferation of plastics and and an increased awareness over the need for recycling. Although the resin code is valuable in that it identifies for consumers and recyclers the types of resin being used, it is often misinterpreted to denote that all plastics with a resin code are actually recycled. In reality, generally only plastics #1 (PETE) and #2 (HDPE) are economical to recycle and thus are accepted widely in curbside programs and dropoff centers.
