The joint research project ZeroCO2 with Mall Umweltsysteme GmbH aims to develop energy-efficient cement substitute building materials based on geopolymer materials from recycled construction waste in order to sustainably reduce CO₂ emissions in the building materials sector. As part of the 8th Energy Research Programme for Applied Energy Research ‘Research Missions for the Energy Transition’, the project is thus making an important contribution to the transformation of the construction industry towards resource-saving and climate-friendly materials.
The use of mineral residues as raw materials reduces both the burden on construction waste landfills and the extraction of natural primary raw materials. At the same time, the recyclability of geopolymer building materials opens up the prospect of long-term closed material cycles in the construction industry, thereby supporting the development of a sustainable circular economy in the building materials sector.
