The platinum group metal (PGM) that was most used to manufacture catalytic convertors worldwide in 2021 was palladium, with demand amounting to nearly *** metric tons. In comparison, platinum demand for catalytic converters amounted to ** metric tons worldwide that year, while rhodium demand amounted to ** metric tons.
Catalytic convertors are installed in automobiles to convert harmful gases from exhaust systems into more benign gases, such as steam.
