Rhodium Recycling: Current State and Potential

Recycling of Rhodium from end-of-life products and manufacturing scrap represents an important secondary supply source. The current global end-of-life recycling rate for Rhodium is approximately 25%, reflecting both technical challenges and economic factors in recovery.

Recycling Rate Context

With a recycling rate of 25%, Rhodium recovery is moderate but has significant room for improvement. Collection infrastructure and processing economics are the primary constraints on higher recovery rates.

Recycling Technologies

Current and emerging recycling technologies for Rhodium include mechanical separation, pyrometallurgical recovery, hydrometallurgical extraction, and direct recycling approaches. These processes mirror primary production techniques such as pgm base metal refinery, adapted for secondary feedstocks. Research efforts focus on improving recovery rates and reducing energy consumption.

Key Recycling Sources

• End-of-life three-way catalytic converters products - Recovery potential varies based on product design, Rhodium concentration, and collection infrastructure.
• End-of-life chemical process catalysts products - Recovery potential varies based on product design, Rhodium concentration, and collection infrastructure.
• End-of-life glass manufacturing products - Recovery potential varies based on product design, Rhodium concentration, and collection infrastructure.
• End-of-life electrical contacts products - Recovery potential varies based on product design, Rhodium concentration, and collection infrastructure.
• Manufacturing scrap - New scrap from fabrication and processing typically has the highest recovery rates due to known composition and controlled collection.

Circular Economy Opportunities

Given the high supply risk for Rhodium, developing robust recycling infrastructure is a strategic priority. The 80% concentration of primary production in South Africa makes secondary supply from recycling an important hedging strategy for consuming nations. Regulatory frameworks such as extended producer responsibility and recycled content mandates are being developed in multiple jurisdictions.
