November 7th 2023 the kick-off meeting of the AG Baustoffe took place at the Helmholtz Institute Freiberg for Resource Technology, set up by the four recomine-projects:

• RepNEU - "Remining by fine particles processing of tin tailings from the Erzgebirge with innovative pNEUmatic flotation technology, more sustainable processing strategies and recycling potential of silicate residues in stones and cobbles"; 
• LiDoVa - "Sustainable Recovery of Vanadium from LD Slags";
• ResuS - "Recycling of Subhydric Sediments";
• Walue - "Holistic Recovery of Recyclable Materials from Rolling Slags".

All four projects have a strong research focus on remining and recycling the mining residues, creating an efficient technology process and the further implementing the result for use in construction products.

Many thanks to all the participants from the Helmholtz Institute Freiberg for Resource Technology, TU Bergakademie Freiberg as well as partners from Chemnitz University of Technology and PICON GmbH, who took part in the discussions on common goals towards a circular economy.
