I thought the point of making them like this was that they technically are reusable, so they can sell them (to people who for some reason keep buying them and throwing them away!) in places where disposable vapes are banned.
One the liquid is low enough, the coil will burn a bit, and the whole thing should be disposed of.
One shop near me would take used ones and send them off to be properly taken apart and what not, but most people just toss them I suspect.
I would be more fine with disposable vapes like this if almost all of them were recovered somehow, for the amount it subsidises production of Li-ion batteries.
On the other hand at least in the US, a deposit of a buck or two wouldn’t do much. California has that for cans and bottles, yet only maybe 10% of people turn them in. Most end up in curbside recycling (which doesn’t refund) or the garbage, indicating people don’t care about getting their nickel or dime back.
