ECO-EFFICIENT PROCESSING AND REFINING ROUTES FOR SECONDARY RAW MATERIALS FROM SILICON INGOT AND WAFER MANUFACTURING
Authors/Creators
Description
In the ICARUS project, 18 European partners collaborate to develop and scale innovative technologies for recovering and refining secondary raw materials from silicon photovoltaic (PV) ingot and wafer manufacturing. The production of PV modules generates significant quantities of waste, particularly silicon kerf, graphite, and silica residues. ICARUS aims to transform these waste streams into high-value secondary materials suitable for reintegration into the PV value chain and other industrial applications. Four industrial pilot-scale processes were developed, targeting the purification and reuse of these materials. Results from the pilots demonstrate both the technical feasibility and economic potential of substituting these recovered materials for virgin and critical raw materials. This work provides a viable pathway toward a more resource-efficient and circular PV manufacturing industry.
