in that scenario why should you get anything? rip it in a way that leaves it in one piece (albeit ripped) and return it. people will get with the program soon enough. after all the entire point of what I propose is to fix the behavior.
It's not an occasional wrapper. It's the block of cheese I finished off when cooking dinner yesterday, the container of mushrooms I emptied, the bag of tortillas. Most household trash just changed from "toss in the trash and it gets dumped somewhere" to "bring to someone to check each item for completeness"?
I'm sure we'd end up with a lot less single-use packaging as a result, but we use single-use packaging for a reason and your proposal amounts to a near-ban. Let's not pretend this is a simple "just charge a deposit and littering stops". It's "charge a deposit, discover the deposit is non-viable, and single-use packaging as a whole stops".
The other commenter's "just put a QR code" helps a lot, but it still makes household trash much more burdensome than the current "put it in a bin and someone collects it" system. How much would you pay to not have to take your kitchen trash somewhere and scan each piece? That's the overhead here.
