Polysilicon Recycling




In the course of polysilicon production as well as during wafer -manufacture and -processing, a considerable amount of scrap and waste in granular and bigger form is unavoidable.


DECKER’s equipment recovers this valuable material down to the fracture of 50μm. The silicon granule is cleaned by acid etching, rinsed , dried and packed. Now it can be sold or directly returned to the production process for new polysilicon.

The system has demonstrated its ability over several years of operation. Poly silicon recycling unit for broken wafers and small particles or granules, recovers this valuable material down to the fracture of 50μm. The silicon granule is cleaned by acid etching, rinsed , dried and packed.
