We provide Nano Filters for the Precision Separation of Critical Metals from waste and wastewater. Sunchem is a nanotechnology organization based out of Lawrence Berkeley National Laboratory. Our mission is to develop Nano Filters for selective metal capture from complex water mixtures to replace inadequate separation technologies in high-value markets such as water purification, energy, and critical metal extraction. Water contamination resulting from extractive operations and manufacturing systems is a worldwide problem, but Sunchem’s Nano Filter technology can provide industries with a cost-effective and energy-efficient approach to improving water quality while also capturing value from their waste streams. This technology has the potential to revolutionize how critical metals are sourced and purified while it protects downstream communities from toxic water pollution.
