As mentioned above, the most extensively studied methods for the removal of resin from glass in silicon-based PV panel recycling involve heating or chemical additives , , . However, we developed a mechanical separation technology to rapidly effect the separation with low environmental load and low energy consumption.
Selective grinding during the initial stage of grinding is effective for removing resin from glass in silicon-based PV panels. Many previous studies on the separation of glass from resin have investigated the applicability of chemical processes, but we achieved separation by brief physical processes.
The selectivity was high at a high rotation speed and during the initial stage of grinding. We found that 97% of the glass in a PV panel can be recovered with less than 1% C contamination for particles smaller than 5.6 mm by grinding at 2500 rpm for 5 min. The resulting glass particles are suitable for use as raw material for glass fiber.
Most silicon-based PV panels have a three-layer structure consisting of flat glass, a cell sealed with ethylene–vinyl acetate (EVA), and a back-sheet made of a multi-layer film comprising polyvinyl fluoride (PVF), polyethylene terephthalate (PET), polyethylene (PE) , and other components.
Selective grinding was used to remove resin from glass particles as a secondary grinding process for the recycling of glass from silicon-based PV panels.
Panels without frames are crushed by the roll crusher, cover glass (broken into small pices) are separated from other components, and rough glass cullet are collected without contamination. Solar cells are remained on a plate form without a damage.
