Over 90% of the glass can be recovered for use in new products and 95% of the semiconductor materials for use in new solar modules. The energy of the polymer incineration could be used in other processes or for pre-heating new charges in future productions. The thermal process recovers 0–98% intact cells depending on prior damage to the modules, type of module structure and the solar cells used. If the cells have edge chippings, micro-cracks, etc., they can normally not be recycled into an intact wafer, and would instead be allocated for obtaining silicon raw material.
