I'm pretty sure the majority of them are not disposed of safely in battery recycling, and even that's imperfect because it does nothing for the other materials and isn't 100% efficient even for batteries.
For that matter we have #RechargeableBatteries now, why are we still selling products require single use batteries or even developing new ones like the disposable phone chargers I've seen for sale in newsagents at train stations?
@afewbugs Totally agree.
I quit smoking early this year, replacing it in favour of vaping. It's honestly so much cheaper, and healthier (degree of health is variable), but these things have sprung up everywhere.
I will always prefer using my own vape, because it's reusable, refillable, reconfigurable, and I like the style. Once it dies, it goes in the tech box to recycle.
These just seem horribly inefficient and like you say, wasteful beyond belief.
