How Are Cars Recycled? The Complete Auto Recycling Process (2026)

The automotive recycling industry processes approximately 11–12 million vehicles per year in the United States, making it one of the country's largest recycling sectors by volume. A car is actually one of the most recyclable products ever manufactured — by design, because early automobile engineers chose steel and other recoverable metals as primary materials.

Step-by-Step Car Recycling Process

Vehicle Intake & Documentation

Vehicle arrives at the facility. Title is processed, VIN is recorded, and the vehicle is photographed. This creates a legal chain of custody and removes the vehicle from the previous owner's name in state records.

Depollution (Hazardous Material Removal)

Every hazardous fluid and material is removed BEFORE any cutting or crushing: gasoline, engine oil, transmission fluid, brake fluid, power steering fluid, coolant/antifreeze, freon (AC refrigerant — requires EPA-certified recovery equipment), battery acid, and mercury switches (found in pre-2003 vehicles). This step is federally regulated under RCRA.

Parts Dismantling

Skilled dismantlers remove all saleable components: engines, transmissions, catalytic converters, alternators, starters, doors, glass, headlights, taillights, rims, tires, seats, dashboards, and electronics. Parts are catalogued, cleaned, and shelved or listed for sale on platforms like Car-Part.com and eBay Motors.

Battery Removal

Lead-acid batteries are removed and sent to battery recyclers, where 99% of the battery's lead is recovered. EV batteries (lithium-ion) require specialized handling and are sent to battery recycling facilities that recover lithium, cobalt, nickel, and manganese.

Hulk Crushing

The stripped vehicle body (now called a 'hulk') is flattened by a hydraulic car crusher to roughly 2 ft tall. This makes it compact enough for economical transport. Crushed hulks are loaded onto flatbed trucks or rail cars and shipped to shredder facilities.

Industrial Shredding

Automobile shredders are massive machines (some capable of processing a car in under 45 seconds) that reduce the hulk to fist-sized pieces. The output is called 'shredded scrap' or 'zorba.'

Metal Separation & Recovery

Shredded material is sorted using magnets (ferrous metals), eddy-current separators (aluminum, copper), and density separation (heavy non-ferrous metals). Each metal stream is baled or containerized and sold to specialty smelters and steel mills.

What Each Material Becomes After Recycling

Material	Recovery Method	End Use
Steel (body, frame, engine)	Magnetic separation → electric arc furnace	New steel for vehicles, appliances, construction
Aluminum (engine, wheels)	Eddy-current separation → aluminum smelter	New auto parts, beverage cans, aerospace
Copper (wiring)	Manual removal or separation → refinery	New electrical wire, plumbing
PGMs (catalytic converter)	Cut out → precious metal refinery	New catalytic converters, fuel cells, electronics
Lead (battery)	Battery sent to lead recycler	New lead-acid batteries (99% recovery rate)
Cast iron (engine block)	Magnetic separation → foundry	New cast iron products
Coolant/antifreeze	Collected and re-refined	New coolant product or industrial use
Engine oil	Collected → re-refining plant	New base oil, industrial lubricant

Frequently Asked Questions

What percentage of a car is recyclable?

Over 80% of a modern vehicle by weight is recyclable. This includes approximately 65% steel, 8–12% aluminum, 2% copper, and smaller amounts of other metals. The remaining 20% (called 'automotive shredder residue' or ASR) includes plastics, glass, and rubber — a portion of which is being increasingly recovered through advanced separation technologies.

How is the steel from cars recycled?

Shredded auto steel is sent to electric arc furnaces (EAFs) at mini-mills, where it's melted and reformulated into new steel products. The EAF process uses recycled scrap as its primary feedstock, making it substantially less energy-intensive than traditional blast furnace steelmaking. Auto steel is used in new vehicles, appliances, and construction materials.

What happens to the plastic in a recycled car?

Plastic recovery from end-of-life vehicles is improving but still challenging. Currently, roughly 50–60% of automotive plastics are recovered. Recycled auto plastic is used in lower-grade applications (drainage products, noise barriers). Some manufacturers now use recycled plastic content in new vehicle production.

Is car recycling regulated in Georgia?

Yes. Georgia DEP and the EPA regulate junk car processing facilities. All licensed facilities must properly handle hazardous materials (used oil, coolant, freon, batteries) according to RCRA and Clean Air Act standards. Unlicensed 'backyard' operations are illegal and subject to significant fines.

Do car manufacturers use recycled materials in new vehicles?

Yes — increasingly so. Ford uses recycled denim in dashboard insulation. BMW uses recycled carbon fiber in its i-series vehicles. The steel in new cars contains a significant percentage of recycled content from end-of-life vehicles. Major OEMs have stated recycled material targets as part of their sustainability commitments.

Conclusion

Auto recycling is one of the most complete material recovery systems ever developed. Your junk car's steel, aluminum, copper, and precious metals all find new purposes — in new vehicles, appliances, electronics, and infrastructure. Selling to a licensed buyer ensures the process is handled safely and responsibly.
