Closed-Loop Recycling to Slash PGM Demand by 40% in 2024, Industry Report Finds

PGM Recycling Revolutionizes Metal Demand with Close to 60% of Platinum Group Metals Being Recycled

In 2024, platinum group metals (PGMs) demand will see a significant reduction of nearly 40% due to the rise in closed-loop recycling, according to a report from UK-based chemicals company Johnson Matthey. With over 60% of PGMs used in new products now coming from recycled metal, the shift towards circularity in the PGM industry is transforming how metals are sourced and used.

Understanding Closed-Loop vs. Open-Loop Recycling

Recycling PGMs is categorized into two pathways: open-loop and closed-loop. Open-loop recycling occurs mainly in consumer markets, where metal ownership is passed along with the product's lifecycle, allowing the metal to be reused for different purposes. In contrast, closed-loop recycling, which dominates industries like chemicals and pharmaceuticals, involves the original buyer maintaining ownership of the metal, reusing it for the same purpose throughout its lifecycle.

This process greatly reduces the need for new PGMs, as the original purchaser reclaims and reuses the metal. In fact, Johnson Matthey's research shows that a substantial 15.7 million troy ounces (toz) of PGMs were recirculated globally in closed-loop systems last year, cutting down the net demand for primary PGMs to 35.4 million toz in 2024.

PGM Recycling Shifts the Industry Landscape

Recycled PGMs, whether through closed or open loops, now make up the majority of materials used in new and replacement products. As primary mining becomes supplementary to the increasing urban PGM mines, it’s clear that recycling is becoming the backbone of the global PGM supply chain. The well-established closed-loop system has proved to be an efficient, sustainable model for metal recycling, potentially setting a precedent for other metals in the industry.

Ryan from Johnson Matthey highlighted that the long-established network of PGM recycling has reached economies of scope and scale through decades of market-driven optimization. This model could serve as a roadmap for other sectors, where the international approach to recycling has not yet reached similar maturity.

Recycling efforts should not be confined within national borders. To ensure efficiency, scrap must be collected and recycled globally, transcending domestic limitations. Ryan advocates for a broader, global collaboration to boost recycling effectiveness and reduce dependence on newly mined metals.
