That 1.3 number is generally accurate, it varies a bit by type of plastic and end-item requirements.

BUT, that 30%, it’s not post-consumer recycled plastic.

It’s the manufacture grinding up the runners, sprues, and bad parts. In the industry it’s called “regrind”. [0]

So if they were trying to tell you it was post-consumer, that was probably misleading.

(Products that use post-consumer recycled plastic will almost always say so, as it is a marketing angle)
