To my mind this is much more justifiable than the plastic straws ban, your drink at the fast food place still comes with a plastic lid containing at least as much plastic as the straw did, but now the straw is paper and go soggy after a while, so you end up getting a second one as a spare just in case, and have you ever tried to stab a hole in a capri-sun drink with a paper straw, I struggle enough when my nephews hand me it and ask me to sort it for them, not sure how they are meant to be abale to do it, and again, straw goes soggy if they don't finish it striaght away.
On other other hand, disposable vapes usually contain a *recharagable* lithium cell in a product where it is used just once, and discarded with a significant amount of charge remaining (use of a standard component to minimise costs, etc), the issues are two fold, not only do rare earth metals get thrown away and often end up just going to landfills, but they can often cause fires in the rubbish. Where I am in lincolnshire, we have an EFW (energy from waste) plant to avoid sending so much straight to landfill (The rubbish is incinerated and the energy used for power generation, unfortunatly when it was built even though there was the idea of a district heating system floated - there wasn't interest in pushing that aspect forward - but I digress). Anyway, instead of local landfills around the place that the individual dustbin lorries would go to, it all has to come to the one plant, now lincolnshire is big county area wise - So the dust carts take the rubbish to "waste transfer stations" (basically big metal sheds) where it is stacked up and loaded into tipper lorries for transport to the efw plant. Fires in these places have become common enough that the county council is investing in automated suppression systems that monitor the area with thermal cameras (probably with some AI imagae processing...) and if an issue is detected, activates a directional jet of water aimed at the relevant area to suppress it enough until the fire service can get there. You might think that if its a metal shed filled with rubbish than a fire is not a problem, but you've got thinks like the JCB loading shovels, highbay lighting so the workers can see what they are doing, odour suppresion, etc that is all at risk of being damaged by a fire, in addition to the structure itself if it gets bad enough. Rubbish can sometimes exhibit self heating effects caused by decay etc, which can start fires on its own, but when you have crushed batteries from vapes etc, it becomes much more of a likely event. I did note that the household waste sites where you can take rubbihs to get rid of now have a dedicated bin just for disposable vapes, which is a good move forward - but how many people know it exists? and/or can be bothered to take them there
