The fibre mats contained within catalytic converters (and diesel particulate filters) can contain hazardous fibres. Refractory Ceramic Fibres (RCF) are classified as a Category 1B carcinogen and end of life catalytic converters should therefore be treated as hazardous waste.
This means that suppliers and users must be aware that products contain RCF when selling on or sending for recycling (extraction of precious metals). Without testing, large numbers of converters containing RCF could be sent for recycling or sold on to third parties without the appropriate precautions being taken.
