FAQ

Resin Identification Codes Explained — questions we get

What does code 7 mean?

Code 7 is “Other”, covering polymers such as ABS, polycarbonate and multi-material items not in codes 1–6.

Does a code mean it is recyclable locally?

The code identifies the polymer; actual recyclability depends on local collection and processing capability.
