THE RIM SUPPLY INDEX
Materials + disposal

Does a plastic type identify the right lid or straw by itself?
PET, PP, PS and PLA are material labels, not interchangeable product or service approvals.

Does compostable mean the straw belongs in every compost bin?
Commercial certification language and actual collection acceptance are separate checks.

Does food-contact language certify the whole cafe setup?
Applicable food and use conditions matter; regulator references are not a blanket finished-product certificate.
