Video: silicon waste inventory

During the production of solar panels large resource flows are generated. Currently some largely end up as waste. Here the challenge in re-use is connected to the material properties: the composition, purity and morphology will determine how the current waste should be processed in order to realize the value potential. SINTEF has therefore performed a waste inventory for three important material flows occurring from silicon-ingot and wafer manufacturing in the PV production value chain: silicon kerf from sawing of wafers, silica from crucibles used in crystal pulling and graphite from crystal growth furnaces. Here silicon is presented.
