  "abstract": "In electroplating processes, palladium makes plastic surfaces conductive for subsequent metal plating. During the production process, small amounts of this precious metal end up in the rinse water. Due to the very low palladium concentrations in the presence of significant amounts of interfering ions, recovering excess palladium from these waste streams using conventional methods is labour-intensive and expensive. An alternative is the use of polyelectrolyte-functionalized adsorbent textiles, which are capable of concentrating palladium from aqueous solutions. Through consistent further development of the associated process technology, it is now possible to selectively adsorb palladium from rinse water with very low concentrations—less than 1 mg/L—even in the presence of a high tin load of more than 200 mg/L, and to recover it. As a result, at our production facility in Germany, approximately 5 kg of palladium—currently with a material value of about $200,000—can be recovered annually from process water and returned to the raw material cycle. At the same time, compared to primary palladium production, this achieves a reduction potential of about 140 metric tons of CO2 equivalents per year. Our R&D work highlights the significant economic and environmental potential of closed-loop raw material cycles in industrial production processes. Furthermore, this approach offers prospects for additional applications in surface engineering and the recovery of critical raw materials.",
