TL;DR
An old appliance is mostly steel, and nearly all of it gets recovered. Before anything is shredded, the refrigerant, compressor oil, mercury switches, and capacitors have to come out. That de-manufacturing step is what separates real appliance recycling from dumping a fridge in a pile.
Homeowners rarely see any of it. What you see is a truck taking a washer away. What happens next is a short, well-defined industrial process.
Step One: Refrigerant Recovery
Any appliance with a sealed cooling loop holds refrigerant. That means refrigerators, freezers, air conditioners, dehumidifiers, wine coolers, and heat pumps. Releasing that refrigerant to the atmosphere is illegal, and recovery has to be done with a machine by a technician who is certified for it.
The technician taps the line, pulls the charge into a recovery cylinder, and logs it. The recovered gas is either reclaimed and resold or destroyed, depending on the type and its condition. Older units may hold refrigerants that are no longer manufactured, which are more valuable to reclaim.
The process itself is short. What it is not is optional, and it is the reason a fridge costs more to handle than a dryer. The mechanics are covered in how refrigerant recovery works.
Step Two: Oil, Switches, and Capacitors
After the refrigerant, the compressor comes off and gets drained. Compressor oil holds dissolved refrigerant and has to be handled as a regulated liquid, not poured off.
Then the processor pulls the small hazardous components. Older units may contain mercury tilt switches in the door light or lid, and older capacitors and ballasts can contain PCB-bearing oil. Both go into separate containers with their own downstream chain.
Glass shelving, plastic bins, and gaskets come out at this point too. They are low value, but leaving them in contaminates the metal stream and drops the price of the load.
Step Three: Shredding and Metal Separation
What is left is a steel shell with a wiring harness and a motor. That goes to a shredder, which reduces the whole thing to fragments in seconds.
A drum magnet lifts the steel out. An eddy current separator throws the aluminum and copper into a different bin. Air classifiers blow off the residual foam and plastic, which is the fraction with the least value and the most disposal cost.
The steel goes to a mill and comes back as new steel. Copper windings from the motor are worth more per pound than everything else in the appliance combined, which is why motors are often pulled and sold separately.
What an Appliance Is Actually Made Of
Rough composition varies by type, but the pattern holds across the category.
| Component | Share of weight | Where it goes |
|---|---|---|
| Steel shell and frame | Most of the unit | Electric arc furnace, back into new steel |
| Motor and wiring copper | A small but valuable slice | Copper refiner |
| Aluminum condenser and trim | Small | Aluminum remelt |
| Plastics and insulation foam | Moderate on refrigerators | Energy recovery or landfill |
| Glass and rubber | Small | Mostly disposal |
The economics tell you something useful. A washer or dryer is nearly all steel, so it has real scrap value and low processing cost. A refrigerator is heavy on foam insulation and requires refrigerant work, so it costs more to handle even though it weighs more. That difference shows up in pricing, and it is the same dynamic described in scrap value in a junk load.
Recovery Certificates and Why They Exist
Utilities that run appliance turn-in rebates, and commercial customers with disposal reporting requirements, often need proof. A recovery certificate documents the unit, the refrigerant type and quantity recovered, and the certified technician who did it.
For a homeowner replacing a fridge, nobody is going to ask. For a property manager clearing twenty units, or a business with a sustainability report, that paperwork is the difference between a documented diversion and a claim nobody can back up.
If you need documentation, ask for it before the pickup, not after. Once a unit is on a shredder floor, the chain of custody is gone.
When an Appliance Is Worth More Working Than Scrapped
Scrap value on a household appliance is modest. Resale or donation value on a working unit is much higher, so the first question is always whether it still runs.
A working appliance under roughly ten years old, clean, with all its shelves and a cord, is usually worth listing or donating. Utility rebate programs sometimes pay for working second refrigerators specifically because a running spare fridge in a garage uses real electricity. Donation intake rules are strict about age and function, which is covered in donating a working appliance.
A dead unit, a unit with a bad compressor, or anything that has sat outside is a recycling job. There is no shame in that outcome, and the material recovery is genuinely high.
FAQ
Can I put an old appliance out at the curb?
Almost never as regular trash. Most municipal programs require a separate bulky item pickup, and units with refrigerant are frequently banned from garbage entirely because the gas has to be recovered first. Check your city's bulky waste rules or use a hauler.
Do I have to remove the doors from an old refrigerator?
If the unit is going to sit anywhere accessible before pickup, yes. Removing the door or the latch prevents a child from getting trapped inside, and many jurisdictions require it. If a crew is loading it directly onto a truck the same day, ask what they prefer.
Does anyone pay you for an old appliance?
Scrap yards pay by weight for clean steel, but the amount for a single household unit is small and rarely covers the trip. Some utilities run rebate programs for working refrigerators and freezers they want off the grid. A dead appliance is a cost, not a payday.
Is it legal to scrap a fridge myself?
You can take a refrigerator to a scrap yard, but you cannot legally vent the refrigerant, and most yards will not accept a unit until the charge has been recovered and tagged. That means paying a certified technician first, which usually costs more than having a hauler take the whole thing.
What happens to the foam insulation in a refrigerator?
It is the hardest fraction to recycle. Some processors capture the blowing agents trapped in the foam, which are themselves greenhouse gases, but capacity for that is limited. Otherwise the foam is separated during shredding and goes to energy recovery or landfill.
Getting the Old Unit Out
Appliances are heavy, awkward on stairs, and easy to damage a doorframe with. A crew that does it daily can have a washer out of a basement in the time it takes to find your dolly. Ask how working units are routed and whether the rest goes to a processor that recovers the refrigerant. If you are weighing your options, start with the best way to dispose of old appliances, then book junk removal or get a quote with the model and location.
