1. A method comprising:
milling a used solar module to create a feedstock comprising polymer and metal; and
sieving the feedstock to obtain a first fraction comprising the polymer, and a second fraction comprising the metal,
wherein sieving the feedstock results in a third fraction comprising metal, polymer and glass, the method further comprising:
subjecting the third fraction to electrostatic separation to create an electrically conducting fraction and a non-electrically conducting fraction.
