Abstract

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.
