FAQS about How is the treatment in photovoltaic panel manufacturing plants

How to deal with solar PV waste material?

Therefore, the methods of dealing with solar PV waste material, principally by recycling need to be established by 2040. By recycling solar PV panels EOL and reusing them to make new solar panels, the actual number of waste (i.e., not recycled panels) could be considerably reduced.

How are PV panels treated?

In some cases, PV panels are treated in WEEE recycling plants that are not specialised in the treatment of PV waste. This implies that the frame is disassembled, while the remaining parts are treated by undifferentiated shredding together with other WEEE.

What is the current treatment of waste PV panel?

(1) Current treatment of waste PV panel is mainly based to the dismantling of aluminium frame and cables, and the further undifferentiated shredding of the panel. The LCA identified some hot-spots of the recycling process.

What materials are expected to be recovered from photovoltaic waste?

Several materials are expected to be recovered from photovoltaic waste after going through the material separation processes as developed in the PV waste treatment. Energy is expected to be recovered from the incineration of EVA and back-sheet layer. The calorific value of these polymers refers to the calorific value of mixed plastics.
