Photovoltaic panel treatment plants must be carefully designed and equipped with dedicated machinery for shredding and screening the waste: CAMEC has developed various solutions for the treatment of category 4 WEEE.
All the components of a photovoltaic panel — the various metals, the aluminium of the module frames, the glass, the cables and the plastic — can be treated by mechanically separating them and reusing each part. This breakdown process yields ferrous metals, non-ferrous metals, glass, silicon and plastic, each of which can be reused to create new products.
The process automatically removes the junction box and aluminium frame, separates and screens the front glass, and then shreds the residual laminate to release the various material fractions. A densimetric table separates copper, metals and plastic granulate by density, while a dedicated system extracts the cell/silicon dust; a bag filter completes the air treatment, ensuring a clean and safe working environment.
