Catalytic converter recycling is the process of harvesting valuable metals from used catalytic converters, which are components in a vehicle's exhaust system that help reduce emissions. The process typically involves removing the catalytic converter from the vehicle, breaking it down into its component parts, and extracting valuable metals such as platinum, palladium, and rhodium. These metals can then be melted down and re-used in the production of new catalytic converters or in other industries. The goal of catalytic converter recycling is to reduce waste, conserve resources, and promote sustainability.
