IIS MATERIALS

Our recycle process is "Refining".

“Heavy-doped” silicon contain high impurities concentrations. It is not be able to reuse as raw material for semiconductor and solar cell. Our refining process can remove the impurities from heavy-doped silicon scrap. Refined silicon can use as raw material for solar cell.

Our domination is that low purity silicon scrap can be refined to high purity silicon.

This refining technology cannot be easily achieved by the other companies. Most of the silicon recycling business that belongs to “Reuse“ of high purity scrap to solar cells. Our process is involving refining process, then the meaning of recycle is totally different from other silicon recycling companies.

This business model is patent fillings.
