Minerit urban

Cele mai de valoare sunt aurul si iridiul dar telefoanele mobile contin mult mai multe elemente reciclabile decat am crede. Japonezii de la Yokohama Metal Co Ltd au calculat ca o tona de gunoi in standard GSM contine, in medie, 150 de grame de aur, 100 kg de cupru si 3 kg de argint. Activitatea celor care sapa prin gropile de gunoi dupa circuite integrate se numeste minerit urban.
