Description
Margery Ryan and co-authors reassessed in 2026 how much platinum group metal recycling really happens, using the market models of Johnson Matthey. Published recycling figures rest on open-market data, which miss metal that loops straight back inside a company. Their estimate counts that closed loop for the first time in print.
Closed-loop volumes turn out far larger than the open-loop flows usually reported as secondary supply. Between half and three fifths of the metal going into new products now comes from recycling, on global average. Because recycled metal carries a far smaller climate footprint than mined metal, the correction matters for sustainability models. Their scenarios show the warming impact of these metals dropping by about tenfold when a closed loop operates. The authors urge routine recovery that keeps metal in use.
