Company Summary

Plus MAT is commercializing a novel and cost-effective system to recover photovoltaic Silicon from wafer sawing waste. With the patented technology from Plus MAT AG, presently lost Si can be recovered as feedstock at a much lower cost (<10$/kg) than the market price (20$/kg). The recovery technology transforms the waste (sawing slurry) into raw material (Si feedstock) for PV production, thus reduces the PV energy production cost significantly.
