Recycling will have an strong increasing energy demand.
To illustrate this, I say "Maybe we will throw in some decades a smartphone into a gas centrifuge, only to obtain with 500 kWh electric power all raw materials perfect separated".
Now I am here in this group for this question.
How many kWh would be necessary to separate in a gas centrifuge a smart phone in all used sorts of atoms?
BTW the new record low price in solar energy is 2,9 Cent per kWh.
So even my wild estimation with 500 kWh would be only US$ 15 for the energy.
