Research Studio Austria „CarboResources“

Project description

Carbon dioxide emissions are the main driving force of global warming, whereas mineral waste constitutes the largest waste stream in Europe. Consequently, the Chair of Waste Processing Technology and Waste Management participates together with the Chair of Mining Engineering and Mining Economics in the Research Studio Austria (RSA) “CarboResources” which is led by the Chair of Process Engineering and follows the approach of Carbon Capture and Utilization (CCU).  Ca and Mg rich mineral resources of primary and secondary origin are dissolved in an acid, impurities are removed and Ca and Mg carbonates for industrial applications are produced.

Project results

The main product of the developed recycling route, precipitated calcium carbonate (PCC),  consists mainly of the CaCO3 modifications calcite und vaterite and has a purity between 79 und 97 % - dependent on the secondary raw material used – and a significantly decreased heavy metals contents comapred to the input material (e.g.Ba, Pb).
