Platinum-Group Metals as Critical Industrial Materials

What this topic covers

Why concentrated supply and essential catalyst uses matter to resilience.

Core catalyst ideas

PGMs combine important industrial functions with geographically concentrated primary supply.

Recycling and material efficiency can reduce exposure to supply disruption.

Substitution is possible in some applications but limited by technical performance in others.

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.
