## What it means

The most widely collected plastic in the world and one of the few recycled back into its original use: bottle-to-bottle PET is routine, and the FDA has cleared recycled PET for food contact under specified processes. It is designed as a single-use container. Repeated washing scratches the surface, which gives bacteria somewhere to sit, and PET softens around 70 °C, so it deforms with boiling water. Rinse and empty; leave the cap on, because loose caps are too small for most sorting lines to catch.

> Defined by ASTM D7611. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.
