The start-up
ROSI valorizes the high quality Silicon contained in the industrial waste in order to re-integrate into its original PV production line.
The need
As an active material for PV, purified silicon (with a purity of 99.9999%) is obtained through a process which is energy-intensive and emits a significant amount of CO2.
The solution
ROSI SAS offers a complete and innovative solution for recycling and revalorising silicon, either from “kerf”, a waste product from the production of solar wafers, or from solar modules at the end of life, in order to reintegrate the waste back into its original PV production value chain. By doing so, ROSI activates a circular economy for the PV industry.
The value proposition
- Revalorises raw materials (silicon and silver) from end-of-life modules for recycling companies.
- Lower production cost for PV and PV silicon producers.
