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.
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....
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.
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.
