Starting in spring 2023, terra mineralia will present the research project "ZauBer - Future materials from Mining Sludge" in the form of a co-growth exhibition. It is funded within the framework of rECOmine.

What is the problem? 
The "Rote Graben" (RG) is used to drain various mines. The 400-year-old artificial watercourse is part of the UNESCO World Heritage Site Mining Region Erzgebirge/Krušnohoří. It is heavily silted and its mine waters are very contaminated with heavy metals. Efficient, ecological and economical solutions are needed for this challenge in a timely manner.

What is the goal of the project? 
The sustainable and environmentally friendly utilisation of ferruginous mine sludge from Roter Graben. The main focus is on the recovery of recyclable materials and the development of new types of building materials. In this way, alternatives to disposal, conservation of landfill space, reduction of CO₂ emissions and ecological improvements for flora and fauna are to be achieved.
