Sounds like they should be banning their sale and/or production then, just like many jurisdictions have been with plastics and other non-recyclable items. These devices are not an essential-to-life item where the waste produced is justifiable, especially when you consider the LiPo batteries, which are a borderline-environmental disaster from the moment the lithium is mined to the day that battery finds its way to a landfill. Why single-use disposable vaping devices exist in the first place is somewhat perplexing given permanent/re-fillable ones are also available, often right beside the disposable ones, and generally offer a significantly lower cost of ownership.

I suspect you could make the same argument for manufactured cigarettes vs pipe tobacco. It seems people will pay for convenience.
