During the manufacturing of photovoltaic panels, a challenging step is the sawing of silicon ingots into very thin wafers. The diamond-wire saw can reach thicknesses below 150 μm but also creates a massive flow of wasted silicon powder in the sawing water called kerf.

With deep roots in silicon purification processes, advanced cleaning and remelting technologies recover highly pure silicon contained in the kerf and reintroduce it into the photovoltaic value chain.

Recycling kerf lowers raw material consumption, reduces energy use in polysilicon production, strengthens supply chains, and significantly decreases the carbon footprint of solar panel manufacturing.
