You are reading this text looking through a transparent conductive material called indium tin oxide (ITO). It is used in electronic screens and also solar cells as a thin coating on the surface. During the manufacturing of these devices, 30 - 70% of the material becomes production waste. Indium is critical raw material. In the technology, the recycling of this waste is integrated into the reproduction process of ITO material which is a CO2 emission-free process and reduces the processing stages.
