I'm still not convinced that phone and laptop ewaste is a real problem. They're tiny. I've never actually thrown one away, they're just sitting around, taking less combined space than a nightstand drawer.
These perfectly good machines will likely be sold off eBay or similar, and / or go in bulk to poorer countries somewhere in Asia, where they are going to replace yet more ancient machines.
reminder that you can get a 10 year old pc with an SSD and any linux disto that will perform as good or even better for most basic office work than modern windows 11 on modern hardware....
I don't throw away phones or computers myself either, but a cursory Googling should be informative. From what I understand, it's a lot of "out of sight, out of mind" in wealthy countries.
