Used catalytic converters, which are devices in a vehicle’s exhaust system that reduce harmful emissions by converting pollutants like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances such as carbon dioxide, water, and nitrogen through chemical reactions facilitated by catalytic materials including platinum, palladium, and rhodium. These converters are imported for the purpose of extracting precious metals and rare earth elements
