Water recovery in raw-material preparation, energy efficiency in refining and closed-loop use of by-products are part of our process design.
Silicon production depends on natural resources and energy. We therefore build sustainability into the process itself: using resources responsibly, designing the process for efficiency and keeping the supply chain traceable.
Environmental impact and long-term availability are assessed when selecting resource sites. Recovery of process water in raw-material preparation, energy efficiency in the refining stages and closed-loop use of by-products are part of the process design.
Through solar-grade polysilicon production we aim to contribute to the development of clean-energy technologies and to continuity of supply. See our Sustainability page for details.
