So much this, in NYC (less available now since Covid), there are dump sites for all this stuff (Batteries, Paint, Heavy Metals) as long as its personal amounts (ie cant come with a dump truck) it is at no cost. If you are a business and can not handle disposal fees, well you are unsustainable and should not exist.
The pi 5 and cm4* have pci-e lanes available. On pi5 you need a daughterboaed to use it.
