I'm a student at Telecom Paris, a school of Paris-Saclay University in France and I'm working on the environnemental cost of phones and SIM cards.
And I'd really like to ask you three questions. It could really help my work !
What's the weight of a micro and nano SIM card, it's my first question.
I know these cards have a plastic part and a chip part. What is the material of this chip and what is its weight itself ?
To what extent these chips are recyclable and reusable ?
Thank you very much in advance,
Best regards,
