Photovoltaic panels contain materials worth recovering from an energy and environmental standpoint. The full value of this material stream is not realized as end-of-life (EOL) panels are disposed of in landfills. Overburden of EOL panels is currently not an issue as most lifetimes are 15~20 years. By 2050, 78 Mt of EOL panels are expected, worth billions of dollars. Current panel designs do not permit reprocessing of entire or broken modules. Subsequently, milling is required for valuable material liberation. Studies focusing on the comminution and separation of PV materials are limited in the literature to date. In this work, comminution and particle separation studies of various types of PV panels are carried out. The effects of various treatments on the particle size distribution and composition are analyzed to determine the degree of comminution and energy requirement. Based on these findings, suitable methods can be applied for a desired separation.
