Samenvatting:
Preliminary Environmental Life Cycle Assessment of solar grade silicon production via gas- and metallurgical route indicates that environmental impacts can be reduced by:
• making efficient use of the metallurgical silicon,
• installing waste heat recovery systems,
• using a clean source of electricity.
The metallurgical route has the advantage of a lower energy consumption compared to the traditional routes with purification via the gas phase resulting in lower environmental impacts.
