PGMs & Recycling
Secondary production or recycling plays an important role in lowering the environmental footprint of global PGM production. With responsible stewardship, PGMs can be recycled over and over again resulting in a continual reduction of the environmental load of each successive life cycle.
In addition, the high value of PGMs drives the recycling of other metals present in PGM-containing products that might not otherwise be recovered.
Using state-of-the art recycling technologies, over 95% of the PGM content of spent automotive catalysts (and other PGM-containing materials) can be repeatedly recovered.
The PGM industry itself repeatedly recycles PGMs from their applications with recovery efficiencies of up to 95 per cent. It collaborates with other stakeholders to increase recycling rates. Targeting the weakest link in the recycling chain provides the best opportunity for improving the recycling rate of PGMs, which in turn can help reduce the overall environmental impact of the PGM supply.
In fact opportunities for improving the recycling rate exist throughout the recycling chain:
