I know that Fairphone is supposed to follow some ethical and environmental principles, but I would like to know the followings questions:
- Does Fairphone includes Coltan or any rare metal that are extracted outside Europe?
- If yes, from which countries are obtained?
- Aren’t any alternatives metals to Coltan?
- Do you know if regular cellphones also include Coltan and other rare metals?
This should answer most of your questions: https://www.fairphone.com/roadmap/mining/ (coltan is the ore from which tantalum is extracted). As far as I know, there are no alternatives.
As far as I know, capacitors made with tantalum (coltan) instead of aluminum or other alternatives have a longer lifespan and less electrical losses. A better capacitor would be made of ceramics but these are simply too big for use in a phone.
