The short answer
How car recycling works: a licensed recycler reports the junk car's VIN to the federal NMVTIS database, then drains the fluids and removes the battery, refrigerant and any mercury switches. Parts that still sell are pulled. The rest is crushed and shredded, the steel is sorted from other metals, and mills melt it down into new steel.
Once a junk car reaches a licensed recycler, the yard logs it and reports its VIN to a federal database, drains the fluids, takes out the battery and other hazardous parts, and pulls anything it can resell. What's left is crushed, shredded and sorted, and the metal is melted down and used again. Knowing how car recycling works also tells you what a buyer is paying for, and what to leave in the car.
Car recycling runs at a big scale. The Recycled Materials Association (ReMA) says more than 15 million tons of steel are recovered each year from about 12 million cars, through a North American network of over 7,000 vehicle dismantlers and 350 shredders (ReMA).
How does car recycling work, step by step?
It happens in six steps, from the paperwork to the steel mill:
| Step | What happens | What it means for you |
|---|---|---|
| 1. Intake | The yard checks ownership and reports the VIN to NMVTIS | Have the title and your ID ready |
| 2. Depollution | Fluids are drained; the battery, refrigerant and mercury switches come out | You don't need to drain anything |
| 3. Parts | Working parts are pulled or sold off the lot | A complete car is worth more |
| 4. Crushing | The stripped body is flattened | Anything left inside is gone for good |
| 5. Shredding and sorting | Steel, other metals and residue are separated | This is why price follows weight |
| 6. Melting | Metal goes to mills, smelters and refiners | Scrap markets move your offer |
What happens when a junk car arrives at the yard?
The first job is paperwork. Federal rules (28 CFR 25.56) require auto recyclers, junk yards and salvage yards to report the vehicles they take in to the National Motor Vehicle Title Information System at least once a month. Each report lists the VIN, the date the yard got the car, who it came from (that part is visible only to law enforcement and government agencies), whether the car was crushed, disposed of or offered for sale, and whether it's headed for export. The rule also covers scrap shredders, scrap metal processors, pull-apart yards and salvage auctions.
That's why a licensed yard asks for the title and your ID before it pays. If there's still a loan on the car, the lender's lien has to be released before the title can change hands. If you can't find the title, deal with that before pickup; some states let older cars be sold without one. On your side, keep a photo of the signed title and file your state's notice of sale. Our guide to the release of liability after selling a car explains what to file and when.
How are fluids and hazardous parts removed?
Before a car can be crushed, the recycler drains its fluids and removes the parts that would pollute: the battery, the air conditioning refrigerant and any mercury switches. North Dakota's guideline for auto salvage facilities is a typical example. It says batteries, mercury switches and all liquids must be removed before vehicles are crushed or shredded, and recommends draining fluids shortly after a car arrives. Other states set their own rules, but the steps look much the same.
- Fuel, engine oil, transmission and brake fluid, coolant and washer fluid are drained into containers. Used oil is recycled or burned for energy, and antifreeze is recycled where possible. The Automotive Recyclers Association (ARA) estimates its industry collects and reuses or recycles about 24 million gallons of motor oil and 8 million gallons of engine coolant a year (ARA).
- The battery comes out early because lead is toxic. North Dakota bans lead-acid batteries from landfills, and ARA estimates the industry collects and reuses or recycles 96% of all lead-acid batteries.
- Refrigerant has to be recovered, since federal law bars venting it. EPA says the last person in the disposal chain, such as a scrap metal recycler, is responsible for making sure the refrigerant in a car's air conditioner is recovered before final disposal. If a car arrives with an empty system, the recycler keeps a signed statement from whoever brought it in (EPA).
- Mercury switches were used in some older cars for trunk and under-hood lights. In 2006, EPA and its partners launched a program to pull those switches from vehicles built before 2002 before the cars are dismantled, crushed, shredded and melted to make new steel. More than 635,000 switches came out in its first year (EPA).
- Tires come off for recycling or disposal. Tire piles can breed pests and are a fire hazard, so states regulate them. North Dakota, for example, allows up to 1,300 tires under a permit-by-rule and requires a formal permit for bigger piles.
Which parts get pulled and resold?
Anything that still works and still sells is pulled for resale or left on the car for customers to pull themselves at a self-service yard. Engines, transmissions, alternators, starters, doors, lights, mirrors, wheels and electronics are typical. What a yard keeps depends on demand for that model in its area and on the car's age and condition. Parts that can be rebuilt, like starters and alternators, often go to rebuilders as cores.
The catalytic converter is usually removed at this stage and sold for the platinum-group metals inside. Our guide to catalytic converter scrap prices covers what sets its value and why it's worth more left on the car when you sell.
All told, ARA says about 86 percent of a vehicle's material content is recycled, reused or used for energy recovery.
What happens when a car is crushed and shredded?
Once the useful parts are gone, the stripped body is flattened in a crusher so more cars fit on a truck, then hauled to a shredder. The shredder tears the car into small pieces. Big magnets pull out the iron and steel, which is the ferrous metal. Other sorting equipment separates the nonferrous metals, such as aluminum and copper. The leftover mix of plastic, foam, glass, rubber and fabric is called shredder residue, and whatever can't be used goes to a landfill.
This is also why junk car prices follow weight: most of what comes out of a shredder is steel sold by the ton. A complete midsize sedan has about $310 worth of metal at $186 a ton (November 2026), and our junk car value calculator estimates the figure for your car.
Where does the metal from junk cars go?
The steel goes to steel mills, where it's melted to make new steel. ReMA says automobiles lead the recovery of steel from discarded consumer products, with a recycling rate near 100%. According to ARA, every ton of new steel made from scrap saves about 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone.
Aluminum and copper go to their own smelters, and the precious metals from converters go to refiners that recover them. Some scrap, and some whole vehicles, are shipped overseas, which is why the NMVTIS report asks whether a car is intended for export.
What does car recycling mean for you as a seller?
The buyer is paying for a car it can take apart, so the way to get a fair price is to hand over a complete car, empty of your things, with the paperwork ready. Our step-by-step guide on how to junk a car covers the whole sale, and the junk car removal page explains how pickup works when you sell through us.
- Leave it complete. The engine, battery, wheels and converter are part of the price, and pulling them usually costs you more than they'd bring on their own.
- Take out everything personal: the glove box, center console, trunk, the space under the seats, toll tags and garage remotes. Once the car is crushed, anything inside is gone.
- Handle the plates the way your state says. In Florida the plates stay with the seller. In California, standard plates generally stay with the vehicle.
- Leave the fluids in. The recycler is set up to drain them and recycle what comes out.
- Tell the buyer about anything missing or damaged, such as the engine, converter or wheels, so the offer matches the car the driver finds.
- Sign the title where the seller signs, keep a photo of it, and file your state's notice of sale if it has one.

Frequently asked questions
What do junkyards do with cars?
They log the car and report its VIN, drain the fluids, remove the battery and other hazardous parts, and pull parts they can sell. The stripped body is then crushed and sold to a shredder, which separates the metal for recycling.
Do junk cars end up in landfills?
Most of the car doesn't. The Automotive Recyclers Association says about 86 percent of a vehicle's material is recycled, reused or used for energy recovery. What's left after shredding, mostly plastic, foam, glass and fabric, is what goes to a landfill.
Do I need to drain the gas and oil before junking my car?
No. Recyclers drain fuel and fluids as part of the process and have the containers and outlets to recycle them. Just tell the buyer if the car is leaking so the driver comes prepared.
Can a junk car be put back on the road?
Sometimes. A licensed yard reports whether each car was crushed or offered for sale, and some repairable cars are resold or rebuilt instead of scrapped. Once a car has been crushed, it's gone. Either way, file your state's notice of sale so you aren't tied to the car after it leaves.
Can you get paid to recycle your car?
Yes. A junk car still has value in its metal and in any parts that can be resold, so recyclers and junk car buyers pay for it. How much depends on the car's weight, age and condition and on what's missing. The junk car value calculator gives a rough estimate before you ask for an offer.
