Extracting platinum ores from the earth is expensive. A more efficient option is recycling scrap catalytic converters. Recycling is always a winner. Reusing expensive platinum, palladium, and rhodium housed in the honeycomb structure of the catalytic converter is most cost-effective. These metals are needed in the manufacture of jewelry, new converters or other industrial applications. The platinum metals are essential because they are the catalyst component for converting the toxic exhaust particles into water and carbon dioxide substances which are natural to our environment. Therefore, there is less pollution going into the atmosphere.
