If the overhead is zero, it's merely charging people for the externality. If the overhead is prohibitively high, it's effectively a ban. I don't see any explanation of how to keep the overhead—in this case, the cost (time or money) of managing returns—low enough to be viable. 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.
