Once the tow truck pulls away, most people never think about their old car again. But what happens next is actually pretty interesting, and it’s a big part of why junking a car is a sensible, responsible way to get rid of it.
Here’s a step-by-step look at what happens to junk cars after they leave your driveway.
What Happens to Junk Cars: The Short Answer
Most junk cars are recorded by the yard, drained of fluids and hazardous parts, stripped of anything resellable, and then crushed and shredded so their metal can be sorted and sold to mills. The details are below.
Step 1: Pickup and Paperwork
The process starts when the buyer picks up your car. You sign over the title (or other ownership documents your state accepts), get paid, and the car is loaded onto the truck.
Behind the scenes, the buyer or yard records the vehicle. Under federal rules, junk yards, salvage yards, and auto recyclers must report the vehicles they take in to the National Motor Vehicle Title Information System (NMVTIS) at least monthly, including the VIN and whether the car was crushed or offered for sale. States add their own requirements, and the title may be marked as junk, salvage, or something similar. These rules help keep stolen cars from being scrapped and keep junked vehicles from being resold as roadworthy.
Step 2: Inspection and Sorting
When the car arrives at the yard, it’s evaluated. Staff look at:
- The overall condition of the car
- Which parts might be worth removing and reselling
- Whether the car should go to a parts yard or straight to scrap
A car with a good engine and clean body panels might spend time in a salvage yard where parts are pulled. A car that’s heavily damaged or very old might go almost directly to processing.
Step 3: Draining Fluids and Removing Hazardous Materials
Before a car can be crushed or shredded, it has to be “depolluted.” Cars contain several materials that can harm the environment if not handled properly, including:
- Gasoline or diesel
- Motor oil
- Transmission fluid
- Coolant (antifreeze)
- Brake fluid and power steering fluid
- Refrigerant from the air conditioning system
- The battery, which contains lead and acid
- Mercury switches, used in hood and trunk lights and some anti-lock brake systems in many vehicles built before 2003
- Tires
Responsible yards drain and capture these fluids and send them for recycling or proper disposal. Some fluids, like oil, can be re-refined. Batteries are commonly recycled for their lead and other materials (see our car battery recycling guide). Tires may be recycled, reused, or processed into other products.
Environmental rules govern much of this process, which is one reason it matters that your car goes to a legitimate, licensed facility.
Step 4: Salvaging Usable Parts
This is where a junk car can get a second life, at least in pieces. Usable parts may be removed and sold to repair shops, mechanics, and do-it-yourselfers. Commonly salvaged parts include:
- Engines and transmissions
- Alternators, starters, and other components
- Doors, hoods, fenders, and bumpers
- Headlights, taillights, and mirrors
- Wheels and tires
- Seats and interior pieces
- Electronic modules
Some yards pull parts themselves. Others operate as “you-pull-it” yards, where customers bring their own tools and remove the parts they need. Either way, reused parts help keep other cars on the road at a lower cost.
The Catalytic Converter
The catalytic converter is usually removed separately. It contains small amounts of precious metals that can be recovered by specialized processors. That’s a big reason why the converter often has an outsized effect on a junk car’s value, as we explain in how much your junk car is worth.
Step 5: Crushing
Once the useful parts and hazardous materials are out, what’s left is mostly a metal shell. Many yards flatten it with a car crusher. Crushing makes the car much smaller, so more of them can be stacked and loaded onto trucks for transport to a shredding facility.
Step 6: Shredding
At a shredding facility, the flattened car is fed into an industrial shredder that tears it into small pieces in a matter of moments. The shredded material then goes through a sorting process.
Step 7: Separating the Materials
The shredded mix contains many materials, and they’re separated using different methods:
- Magnets pull out steel and iron, which make up much of a car’s weight.
- Other separation systems recover non-ferrous metals such as aluminum and copper. Our guide to the scrap metal in cars breaks down what’s recovered.
- Leftover material, such as plastics, foam, glass, and fabric, is sorted further. Some of it may be recovered, and the remainder is typically disposed of.
Step 8: Recycling the Metal
The recovered metals are sold to steel mills, foundries, and other manufacturers. There, they’re melted down and made into new products, which can include new cars, appliances, building materials, and countless other items.
Recycling metal generally takes less energy and fewer raw materials than producing it from mined ore. That’s a big part of why junk car recycling is considered a good thing for the environment, and why scrap metal has real market value in the first place.
Why It Matters Where Your Car Goes
Not every operation handles cars the same way. Choosing a reputable buyer or licensed yard helps make sure:
- Fluids and hazardous parts are handled properly
- The car is reported correctly under your state’s rules
- The title transfer is done right, so you aren’t on the hook for the car later
You can find licensed yards and buyers near you in our junkyard directory or on our service area page.
Your Part in the Process
You don’t need to do any of the recycling yourself, but you can help things go smoothly:
- Remove personal belongings before pickup.
- Tell the buyer about any leaks or damage, especially flood or fire.
- Handle plates, registration, and insurance after the sale. See our guide on license plates and insurance when junking a car.
- Keep your receipt or bill of sale as proof the car left your hands.
FAQ
Will my car be resold instead of scrapped? Sometimes. If a car is repairable, it may be sold rather than scrapped, depending on its condition and your state’s title rules. Many junk cars, though, are parted out and recycled.
Do I need to drain the fluids before pickup? No. Yards handle that. Just let the buyer know about any major leaks.
How much of a car can be recycled? A large share of a typical car, especially its metal, can be recovered and reused. The exact amount depends on the vehicle and the facility.
Is my personal information safe once the car is gone? Clear out paperwork, garage openers, and toll tags. If your car has a built-in infotainment system, consider deleting paired phones and saved addresses before pickup.
