Three different process approaches to PV panel recycling are distinguished and detailed in the remainder of the section: physical treatment and EVA dissolution with organic solvents, thermal treatment, and chemical processes. Processes relying on the combined application of these process approaches are separately discussed. 7.1. Physical treatment
Can shredded EOL PV panels be recycled?
Volume 72, pages 2615–2623, (2020) One of the technical challenges with the recovery of valuable materials from end-of-life (EOL) photovoltaic (PV) modules for recycling is the liberation and separation of the materials.
