Physical and chemical treatment of end of life panels: An integrated automatic approach viable for different photovoltaic technologies

Autor: Emanuela Moscardini, Tomas Havlik, Thomas Abo Atia, Francesca Pagnanelli, Luigi Toro, Pietro Altimari, Giuseppe Granata

Publikováno v: Waste Management. 59:422-431

Different kinds of panels (Si-based panels and CdTe panels) were treated according to a common process route made up of two main steps: a physical treatment (triple crushing and thermal treatment) and a chemical treatment. After triple crushing three
