I mean, watching a guy in a muscle car throw trash out his car at the intersection near my home, I’m for it. It ain’t so much the littering, it’s the type of people who litter. Lol
Even if it was scattered everywhere you would definitely have people pick it back up for the deposit. That works with bottles in Germany and the deposit for them gets as low as 8ct.
Because the deposit is tied to inflation. Older products might end up with way outdated deposits if you print the sum on the packaging, so it would have to be token based. The token is then inflation safe.
