The Leipzig-based company Ceritech is pushing ahead with the goal of producing rare earths without mining. They are going to be able to produce quantities equivalent to a serious conventional mine. To this end, Ceritech is developing an unconventional method for extracting rare earths from plasters. The gypsums are produced in large quantities in the production of fertilizers and, depending on the location, have good levels of rare earths. The approach is environmentally friendly and economical.

For Ceritech, TRADIUM is active in an advisory capacity with regard to product design and market needs in the German and International areas. Managing Director Matthias Rüth also sits on the Supervisory Board of Ceritech.
