Revalorising silicon from production and product waste to contribute to a circular economy in PV
ROSI Solar is a company offering innovative solutions for recycling and revalorisation of raw materials in the solar photovoltaic industry. The technologies allow to recover ultra-pure silicon and other metals currently lost during the production of photovoltaic cells and at the end-of-life of solar panels.
The need
As an active material for PV, purified silicon (with a purity of 99.9999%) is currently obtained through a laborious process which is both energy-intensive and emits a significant amount of CO2.
The solution
ROSI offers a complete and innovative solution for recycling and revalorising silicon. It does so either from “kerf”, a waste product from the production of solar wafers, or from solar modules at the end of their life. What was once considered waste is reintegrated back into its original PV production value chain, activating a circular economy for the PV industry.
The value proposition
- Revalorisation of raw materials for recycling companies, including silicon and silver from end-of-life modules.
- Lower production costs for PV panels and PV silicon producers.
- A treatment capacity of 3,000 tonnes of photovoltaic panels from 2023 set to reach 50,000 tonnes by 2027.
