A nice anecdote here from Fairphone, giving an example of how (unpaired!) parts can be used again and again over time in multiple devices.
This is just one of many examples that pop up through our reuse and recycle program. Your old phone is a veritable treasure trove of spare parts and resources, things that go a long way in repairing other phones and making new ones, without taxing the planet further.
Just last year alone, we recovered around 16000 parts in good and not-so-good conditions!
