Tangential question: is it ok to recycle any PET, or just bottles? Where I'm from, the recycling spots at stores emphasize they're taking bottles only, but PET is used in a lot of other packaging as well. To me it's a no brainer any PET should go to the recycling, but they seem strict about having bottles only.
