Resin Codes

Wonder what those symbols on or near the bottom of a plastic container mean? They are plastic resin codes and identify the resin. These codes do not necessarily mean that a container is recyclable since there may not be a recycling market for a particular code. The following list will help you learn about the codes so you know which items to include in your local curbside or drop-off recycling program.
