Mechanische Aufbereitung von Feinfraktionen aus Abfallströmen

In nearly all processing and recycling pathways for waste, alongside products that can be reused as raw materials, residual materials are also generated, which are usually sent to landfills. In the spirit of a circular economy, it is desirable to create meaningful utilization options for these materials as well. However, the more heterogeneous and finer these fractions are, the more challenging their processing becomes.
The project „Mechanisch-thermochemisches Recycling von Feinfraktionen“ (short: MeteoR; project number: FO999897764), within which this master's thesis was developed, focuses on investigating precisely these fractions. The aim of this work is to process specific material streams, such as demetallized incineration bottom ash, municipal and commercial waste, as well as fractions from mechanical-biological waste treatment, using equipment like screens, magnetic separators, eddy current separators, and density sorters. This should produce concentrates that can be used specifically in metallurgical processes, the cement industry, and other industrial sectors. This approach reduces the consumption of primary resources as well as the required landfill volume, thereby making a contribution that is both economically and ecologically valuable for the environment.
