Why a plastic resin number does not guarantee recycling

A resin code identifies plastic type but not local collection eligibility; check rules and clean food residues.

The triangle-like resin code is often mistaken for a promise that an item is recyclable. The US EPA explains that it identifies plastic type but does not guarantee a local collection program accepts it. Local guidance takes priority.

Your try-it-at-home checklist

0 / 6 done

Read current municipal or building recycling rules for accepted plastic items.
Treat the resin number as material information only; acceptance can also depend on shape and mixed materials.
Empty packaging and scrape or lightly rinse food residue as local rules require.
Check plastic bags, films and foam separately because collection programs may handle them differently.
Do not mix compostable plastics into conventional recycling; check whether an approved composting stream exists.
If uncertain, consult the local collector rather than placing a questionable item in the recycling bin.
