Utforskning av mulighetene rundt superkritisk CO2 ekstraksjon for utvinning av PGM fra kretskort

Offentlig prosjektsammendrag

Recycling PCBs is economically beneficial due to their valuable metal content. Recovering these metals, especially platinum group metals (PGMs) like palladium, is crucial as they are in high demand but scarce globally. Europe faces challenges due to limited PGM resources. This research explores sustainable metal recovery methods from PCBs, focusing on advanced extraction processes like supercritical CO2. The method will be tested for feasibility and efficiency in extracting PGMs, optimizing conditions such as pressure, temperature, and flow rate. It is cost-effective, non-toxic, and ideal for heat-sensitive materials, making it an environmentally friendly option for in-plant recycling. In conclusion, this study highlights advanced extraction methods as a green alternative for metal recovery from waste PCBs, emphasizing their economic and environmental benefits. Optimizing these processes is key to sustaining precious metal supplies and addressing resource limitations.
