The issue of recycling old household appliances becomes relevant for many owners when the unit finally breaks down. Often there is a desire not only to get rid of a bulky item, but also to get at least some money for it by handing over the case to a collection point. However, few people think that inside the “white box” there are different types of materials hidden, the cost of which on the recyclables market is radically different.
A simple solution - calling movers and giving away the entire refrigerator - most often means losing a significant part of the potential profit. Reception points, when purchasing an assembled device, evaluate it as black scrap, ignoring valuable components. To get the real market value, you need to understand the structure of the unit and know which elements should be removed yourself before weighing.
In this article we will analyze in detail what exactly from the contents of the refrigerator is valuable to buyers, how to safely dismantle the components and what final amount can be expected. You will find out why copper is valued higher than aluminum and whether it is even worth bothering with disassembly for a couple of kilograms of precious metals.
Cost structure: ferrous and non-ferrous metals
The bulk of any household refrigerator is steel. This includes the body, shelves, doors and interior lining. In the recycling market, this material is classified as ferrous scrap metal (Fe), and its price per kilogram is the lowest among all recyclable materials. If you hand over the entire refrigerator, you will receive payment at exactly this rate, which rarely exceeds the cost of ordinary construction scrap.
However, inside the structure there are elements made of non-ferrous metals, whose liquidity is much higher. First of all, we are talking about copper i aluminum. The compressor, which is the heart of the refrigeration machine, contains windings made of copper wire. Heat exchangers (condenser and evaporator) can also be made of copper or aluminum, depending on the year of manufacture and model of the device.
The difference in price between black scrap and purified copper can reach five times. That is why proper sorting allows you to turn recycling into a small but pleasant bonus. It is important to understand that buyers accept mixed scrap at the price of the cheapest metal in the mixture, so separation of materials is a key step.
⚠️ Attention: Scrap prices constantly fluctuate (fluctuate) depending on stock quotes and the demand of processing plants. The exact cost per kilogram in your region must be clarified directly at the reception point before the trip.
In addition, it is worth considering the weight of each component. The steel body is heavy, but cheap. Copper coils are lightweight but expensive. Aluminum radiators occupy an intermediate position. The effectiveness of disassembly depends on how much non-ferrous metal can be extracted from a particular model.
Compressor: where to look for copper and oil
The most valuable element in a refrigerator is the compressor. This is a sealed unit, usually located at the lower rear of the device. Inside its casing there is an electric motor and a piston group. For metal testing, we are primarily interested in the motor winding, made of copper.
Dismantling the compressor requires caution. It is attached to the frame with four shock absorber legs and connected to a tube system. Before removing, you need to cut through the copper tubes going to the condenser and evaporator. After this, the unit can be removed and taken out for further cutting.
To get to the non-ferrous metal, the compressor casing must be opened. This can be done using a grinder or a hacksaw. Inside you will find a stator with copper winding. The weight of pure copper that can be extracted from one compressor varies from 0.5 to 1.5 kg, depending on the motor power.
Is it necessary to drain the oil from the compressor?
When the casing is opened, technical oil may leak out of the compressor. It is a waste petroleum product and is classified as hazardous waste. Draining it onto the ground or into a sewer is strictly prohibited. Collect the liquid in a sealed container and take it to a designated hazardous waste collection point or dispose of it in accordance with local environmental regulations.
It is also worth paying attention to the tubes that go to the compressor. They are often made of high quality copper. Their length can be several meters, which in terms of weight gives a significant addition to the final amount. Aluminum tubes are less common and are less expensive.
Heat exchangers: condenser and evaporator
The refrigerator cooling system consists of two main heat exchangers: a condenser (located at the back, often in the form of a grill) and an evaporator (located inside the freezer or refrigerator compartment). The material they are made of directly affects the final revenue.
Widely used in older models released before the mid-2000s. copper. The rear grille in such refrigerators is a solid copper coil. Its dismantling is simple: the tubes are cut at the entrance and exit, and the grille is removed entirely. The weight of copper in such a radiator can reach 2-3 kg.
To save money, modern manufacturers have switched to aluminum or coated steel. Aluminum grilles are lighter and softer, their cost at the receiving point is lower than copper, but still higher than that of ferrous metal. You can determine the material visually (copper has a characteristic reddish tint on the cut) or using a magnet (copper and aluminum do not magnetize).
The evaporator inside the chamber can also be copper or aluminum. In No Frost systems, the evaporator is often hidden behind a plastic panel and is a complex aluminum radiator with a fan. Its removal requires partial disassembly of the internal space.
Electrical and other contents
In addition to the main components, there are other components in the refrigerator that should not be thrown into the general heap of ferrous metal. Wiring, electronic control units and even some fasteners may contain valuable materials.
First of all, pay attention to the power cable. If it is long and of high quality, it can be stripped and sold as a copper core. The control unit (if it is electronic and not mechanical) contains boards that contain microcircuits. Although the content of precious metals in consumer electronics is microscopic, some buyers accept boards separately.
- 💡 Fans: No Frost systems have fan motors containing a small amount of copper in the winding.
- 💡 Fasteners: aluminum or brass mounting elements for tubes and panels can be assembled into a separate container.
- 💡 Freon: the refrigerant has no value for the dealer, but its release into the atmosphere is harmful to the environment. During professional disposal, freon is pumped out.
Do not forget about plastic elements. Shelves, drawers, door handles are plastic that can also be returned, but in special containers for PET or plastic, and not metal. Mixing plastic with metal will reduce the weight of useful scrap, since the receiver will subtract the mass of non-metallic inclusions.
Tools and safety precautions during disassembly
Disassembling a refrigerator is a process that requires certain preparation and compliance with safety precautions. The design of the unit is sealed, and some parts are energized until switched off. Incorrect actions can lead to injury or property damage.
Before starting work, you must unplug the refrigerator and let it stand for several hours. This is necessary not only to defrost the ice, but also to ensure that the refrigerant and oil in the system come into balance, and the capacitors in the electronics are discharged.
☑️ Preparation for disassembly
For work you will need: wire cutters or side cutters for cutting pipes, screwdrivers (Phillips and flat), pliers, possibly a grinder or a hacksaw for opening the compressor. Be sure to use thick gloves to avoid cutting yourself on the sharp edges of the steel body and internals.
⚠️ Attention: When cutting through the copper pipes of the cooling system, residual freon pressure may escape. Although modern refrigerants (R600a, R134a) are not toxic in small doses, inhaling their stream is not recommended. Work in a ventilated area or outdoors.
Take special care when working with an angle grinder. Sparks from the tool may ignite residual oil or insulation. If you open the compressor, do it carefully so as not to damage the winding that you plan to remove.
Economic calculation: is it worth the candle
Before embarking on the labor-intensive disassembly process, it is worth conducting a simple economic analysis. Handing over the entire refrigerator takes 10 minutes: they take it out, weigh it, and receive the money. Self-cutting can take from 1 to 3 hours, requiring physical effort and the presence of tools.
Consider an approximate calculation for a standard two-chamber refrigerator weighing 60 kg. When you hand it in complete, you will receive payment only for 60 kg of ferrous scrap. If you disassemble the device, the picture will change.
| Component | Approximate weight | Type of metal | Liquidity |
|---|---|---|---|
| Case, doors | 45 kg | Steel (black scrap) | Low |
| Compressor (copper) | 0.8 kg | Copper | High |
| Grid (capacitor) | 2.5 kg | Copper/Aluminium | Medium/High |
| Wiring, motors | 1.0 kg | Copper/Aluminium | Average |
As can be seen from the table, the bulk still constitutes steel. The benefit from disassembly consists of the difference in price per kilogram of non-ferrous metals. If you have an old refrigerator with a copper grill and a powerful compressor, profits can increase by 30-50% compared to selling it completely. In the case of new models, where everything is made of aluminum and steel, the difference will be minimal.
It is also worth considering logistics. Unloading 5kg of copper and 50kg of steel separately can be more difficult than unloading 55kg of mixed cargo alone. Some collection points have a minimum weight threshold for non-ferrous metals or do not accept small lots from individuals at high prices.
Environmental aspect of disposal
By disassembling the refrigerator yourself, you take responsibility for the correct disposal of all its components. You cannot simply throw the compressor with oil or plastic parts into a common container. This is harmful to the environment.
Oil from a compressor is a petroleum product that pollutes soil and water bodies. Freon, although in small quantities, is a greenhouse gas. Plastic takes hundreds of years to decompose. A competent approach involves handing over each type of waste to the appropriate container or collection point.
By handing over metals for recycling, you contribute to the conservation of natural resources. Melting scrap requires significantly less energy than mining and processing ore. Thus, even old household appliances can become a source of raw materials for new products.
In conclusion, it is worth noting that selling a refrigerator for metal is not a way to get rich, but an opportunity to wisely get rid of old property. If you approach the matter wisely, you can cover the cost of removing new equipment or simply get a nice amount of pocket money, while clearing your space and conscience.
Is it possible to return a refrigerator for free?
Yes, in many cities there are recycling programs or promotions from household appliance stores. When purchasing a new refrigerator, the store may offer removal of the old one for free or at a discount. There are also municipal services that remove bulky waste, but often you have to pay for it yourself.
Do they accept refrigerators with rust?
Yes, rust is not an obstacle to acceptance. On the contrary, rusty metal is easier to recycle in some processes. However, severe corrosion can reduce the weight of the product, since iron oxides weigh differently than pure metal, but in practice this rarely affects the price significantly.
Is it necessary to remove freon before delivery?
For individuals, when delivering metal to collection points, removal of freon is usually not required - this is already done at a factory or specialized enterprise. However, releasing freon into the atmosphere yourself is not recommended for environmental reasons. When disassembling the compressor, the gas will come out on its own if the system was sealed.
Where can I find current prices for scrap?
Current prices are published on the websites of large scrap metal collection points in your city. Information can also be found on specialized portals that track stock quotes of non-ferrous metals. Remember that the price in the advertisement and the price on the scales may differ.
