What we do
Silicon is the raw material for modern solar cells and a sustainable production of silicon the foundation for renewable energy. Recycling silicon is the first step to a carbon-neutral silicon production. The second step is using renewable raw materials.
Recycling Silicon Kerf
During production of solar cells half of the silicon is lost as silicon waste. We up-cycle this low-quality waste to high-quality silicon metal. This can be used as a fresh feedstock for production of solar silicon and subsequently solar cells.
Renewable Solar Silicon
Production of silicon consumes quartz and coal. Every solar cell is thus connected to the consumption of fossile resources. We work on a technology to produce silicon from renewable raw materials – rice hulls and sugar.
