Although scrap catalytic converter prices vary according to the brand and model, refining systems provider Proses Makina notes that the precious metals contained in the catalytic converter influence the price and monetary value, meaning that the price of a catalytic converter could vary from between $6 up to $800. “Logically, this means that the more precious metals it contains, the higher the scrap metal price. However, increasing platinum, palladium and rhodium prices also influence the price,” the company says.
