Closed-Loop Recycling Slashes PGM Demand by 40% in 2024

Johnson Matthey Highlights a Game-Changing Shift in the Platinum Group Metals Industry

Global demand for new platinum group metals (PGMs) dropped sharply in 2024 due to a surge in closed-loop recycling. According to a white paper released by UK-based Johnson Matthey, nearly 60% of PGMs used in new production now come from recycled sources.

Closed-loop recycling plays a critical role in this reduction. In this model, the original buyer retains ownership of the metal, recycles it after product use, and reuses it for the same application. This contrasts with open-loop systems, where the metal changes hands and often shifts purpose across industries. Because closed-loop PGMs never re-enter the broader market, they are not counted as secondary supply — yet they substantially reduce the need for newly mined metal.

In 2024, an estimated 15.7 million troy ounces of PGMs circulated through closed-loop systems globally. This recycling process slashed net demand for new PGMs by nearly 40%, reducing it to just 35.4 million troy ounces. As a result, recycled materials from both open- and closed-loop sources now dominate the PGM supply chain. Primary mining serves as a supplement rather than the main source.

Urban mining is now central to the industry’s survival. Without it, the sustainability of PGM production would falter. Johnson Matthey’s Advocacy Manager for PGMs, Marge Ryan, emphasized that the industry’s closed-loop model could serve as a blueprint for broader metals recycling initiatives.

Despite its success, this global recycling network is not yet mirrored across other metal sectors. Many nations still focus heavily on domestic circularity efforts. Ryan argues for a broader, cross-border system. “Scrap collection and recycling don’t need to be confined by national borders,” she said. A coordinated global framework could unlock similar benefits for aluminum, copper, rare earths, and more.

The evolution of the PGM recycling ecosystem underscores a pivotal shift — not just in metals demand, but in how the world approaches sustainability, material ownership, and industrial efficiency.
