I didn't know chatGPT could spit out sources, that's neat. I'll have to give it a shot some time. Did you specifically ask for that or did it do that on its own?

The PET vs Glass study is fascinating, especially since the result favors PET by a significant margin. That's a massive disconnect from the findings of the OP study. It basically makes PET out to be a fantastic option, but assuming it can be so clean, it's even more infuriating that so little plastic gets recycled. I also wonder what the breakdown of PET recycling is, vs plastics in general? Is it just a tiny portion of plastic waste overall, or does it fail to reach the recycling stream? Something about that situation stinks, and not just of uncleaned bottles.

Considering that we have to reduce virgin material use in every sector, the more recyclable option should be the clear winner. Its frustrating to see this level of waste.
