Secondary PGM Supply

What this topic covers

Recycled automotive, industrial and energy-system materials as sources of platinum-group metals.

Core catalyst ideas

Secondary PGM supply comes from collected products and industrial residues.

Recovery economics depend on metal content, collection efficiency and processing cost.

Different scrap streams require different sampling and refining systems.

System tradeoffs

Representative sampling and assay are critical to metal accounting because spent catalyst is often heterogeneous.

Performance evidence

Recycling reduces primary-material demand but still involves collection, processing losses and energy.

Lifecycle perspective

Extraction and refining methods are hazardous industrial operations and are outside this site's procedural scope.
