Why Scrap Catalytic Converters Are Valuable
Catalytic converters are among the most valuable single components on a scrap car, and the reason is what's inside them: platinum, palladium, and rhodium.
These three precious metals coat the honeycomb core and trigger the chemical reactions that clean your exhaust gases.
All three are rarer than gold - and rhodium, at its market peak, has traded at many times gold's price. Because catalytic converter values are tied directly to these metal markets, prices change daily, which is why two identical-looking cats can be worth very different amounts on different days - scrap car prices move with the metal markets.
When you scrap your car with Remove My Car, the catalytic converter's value is included in your scrap car price - you don't need to remove it, sell it separately, or do anything at all.
What Affects a Catalytic Converter's Scrap Value
Not all cats are worth the same. The main factors are the type of vehicle it came from (larger engines generally carry more precious metal loading), whether it's an original equipment manufacturer unit or a cheaper aftermarket replacement (OEM cats contain significantly more recoverable metal), the age and condition of the unit, and above all - the current market prices of platinum, palladium, and rhodium, which move daily on global commodity markets.
Hybrid vehicles deserve a special mention: their catalytic converters often work less hard and corrode less, which is why they tend to hold higher value - and why hybrids have been disproportionately targeted by converter thieves.
Should You Remove the Catalytic Converter Before Scrapping Your Car?
No - and this matters. Your scrap quote assumes a complete vehicle, and a car arriving at the ATF with its catalytic converter missing will be worth substantially less; in most cases the deduction outweighs anything you'd make selling the cat separately.
There's a safety issue too: the inside of a catalytic converter is classed as hazardous waste once opened, and breaking into one without specialist equipment exposes you to toxic material.
And if you do sell a converter to a scrap metal dealer, the same rules apply as for your car - payment must be traceable, never cash, under the Scrap Metal Dealers Act 2013. The simple version: leave the cat on the car, and its value comes back to you through your quote.
How Catalytic Converters Are Recycled
When your scrap car reaches an Authorised Treatment Facility, the catalytic converter is removed as part of the depollution process, stored, and passed to a specialist recycling company.
The recyclers extract the platinum, rhodium, and palladium from the ceramic core and recycle the metal casing.
The recovered metals go on to be used in medicine, dentistry, electrical components, jewellery — and new catalytic converters.
If you'd like to see this happen first-hand, SAR Recycling Ltd in Immingham has a public viewing area where you can watch the processing.
Hazardous Waste or Controlled Waste?
An intact catalytic converter is classed as controlled waste at an ATF, because sealed units pose no significant risk. But the moment a converter is opened and its ceramic bricks are exposed to the air, it becomes hazardous waste and must be handled and disposed of accordingly — one more reason this is a job for trained specialists, not a hacksaw in the driveway.
Catalytic Converter Theft: Why Thieves Want Them
The same precious metals that give your cat its scrap value have made converters a target for thieves, who can cut one from under a parked car in under a minute.
If your car's converter has been stolen, it will affect your scrap quote - but the car is still worth scrapping and doing it through a licensed ATF ensures what remains is recycled properly and legally.
