I work on the utilization of sensor based sorting equipment in order to separate valuable particles (e.g. metals or plastics) from landfill material during mechanical processing. Thereby the defilements complicate the sorting in particular. Therefore I will study the influence of defilements on sensor based sorting and work on wet-mechanical treatment in order to reduce defilements, creating high quality recyclable material. Any questions or wishes? You can write me an e-mail at email@example.com.
