Membrane mining: Sustainable extraction of high-tech metals

The Audi Environmental Foundation has joined forces with the Freiberg University of Mining and Technology to research new ways of mining high-tech elements. These metals and so-called rare earths are indispensable for modern technologies such as fiber optics, photovoltaics, and semiconductors. Membrane technology is used to mine the raw materials underground in an environmentally friendly and sustainable manner.
