Segmentation by type distinguishes the physical and procedural forms of rhodium recovered, each contributing uniquely to the market’s volume. Primary rhodium—directly reclaimed from spent catalytic converters—forms the bulk of supply, estimated at 65% of total recycled output, because it retains high purity suitable for resale to catalyst manufacturers. Secondary rhodium—derived from jewelry plating waste and electronic scrap—accounts for 25%, offering a lower‑grade material that often requires additional refining but serves cost‑sensitive end‑users. Alloyed rhodium, recovered from mixed‑metal alloys in industrial residues, makes up the remaining 10%; its value lies in specialty applications where alloy composition is critical. By differentiating these types, analysts can assess processing costs, recovery efficiencies, and downstream pricing, thereby refining the market taxonomy and informing investment decisions across the recycling ecosystem.
