To develop the full potential of recycled concrete to bind CO2 and to reuse it as a building material is the primary ambition of the transdisciplinary research project C2inCO2. By developing optimized treatment processes and efficient carbonation methods, the project aims at closing the CO2 and material cycles in concrete production and thus significantly reducing CO2-emissions from the cement and concrete industry.
The CO2-LiPriSek project aims to develop and evaluate a universal, economical process for the extraction of marketable lithium from lithium-containing ores and industrial waste. By means of direct carbonation, different raw materials (e.g. lithium-containing ores, battery residues) are to be converted into lithium carbonate of battery grade quality (bg-Li2CO3 >99.5 %).
The NuKoS project aims to increase the resource efficiency of the industry by using CO2. To this end, raw gases containing CO2 are to be used in slags from steel and metal production that have not yet been subjected to high-grade material recycling. On the one hand, CO2 can thus be recycled and on the other hand the amount of materials to be landfilled can be significantly reduced. The generated products are to be used as high-quality secondary raw materials (e.g. carbonates) in various branches of industry.
