Zusammenfassung:	The following disclosure relates to a method for separating fluoropolymer layers from a substrate, the method comprising: contacting the substrate with an ionic liquid comprising an organic acid and an organic base to dissolve at least one layer of the fluoropolymer from the substrate. The disclosure further relates to a method of dismantling solar panels for recycling using said method, as well as a method for producing glass fines from photovoltaic glass, comprising: milling the photovoltaic glass to produce glass fines, wherein at least half the glass fines have a particle size of less than 83 µm, and optionally using said glass fines in building materials. La présente divulgation porte sur un procédé de séparation de couches de fluoropolymère d'un substrat, le procédé consistant à : mettre en contact le substrat avec un liquide ionique comprenant un acide organique et une base organique pour dissoudre au moins une couche du fluoropolymère du substrat. La divulgation concerne en outre un procédé de démontage de panneaux solaires en vue d'un recyclage à l'aide dudit procédé, ainsi qu'un procédé de production de particules fines de verre à partir de verre photovoltaïque, comprenant : le broyage du verre photovoltaïque pour produire des particules fines de verre, au moins la moitié des particules fines de verre ayant une taille particulaire inférieure à 83 µm, et éventuellement l'utilisation desdites particules fines de verre dans des matériaux de construction.
