The thing with bottle deposits is: it really only annoys the people who generally already do the right thing anyway.
Here in the Netherlands, we expanded bottle deposits to cans and small bottles last year. A 15-25 cent deposit.
It’s causing all sorts of problems: deposit machines are breaking down in record numbers and there’s too few of them. A lot of places sell cans and bottles, but a lot of them don’t take returns. This means that it’s a giant hassle to return the cans and bottles, so a lot of people now just see it as a price increase and don’t bother with the return.
The deposit also causes MORE litter in the streets. How? Because we’ve effectively incentivised the homeless and drug addicts to break open trash bins and search for cans and bottles. They break one open, tear out the trashbag, dump the contents and take the bottles. Which attracts rats, since they leave the rest. My city now regularly looks like a garbage dump.
Meanwhile, some call it a succes because ‘there’s fewer bottles and cans on the streets’, while conveniently ignoring literally all the other trash that now gets dumped on it.
I’d honestly vote today to abolish the deposit scheme. Sounds good on paper, but in practice I’m only seeing downsides.
