How to properly pack empty cans before scrapping: 7 steps to save time and space

Recycling empty drink cans, cans, or paint cans is a great way to make money from scrap metal, free up space in your garage, and contribute to the environment. However unprepared banks may lead to refusal, underpricing, or even injury during transportation. Sharp edges, liquid residue, rust or improper packaging all reduce the cost of raw materials by 15-30%. In this article we will look at how flatten, peel and pack different types of jars to get the maximum benefit and avoid common mistakes.

Many people think that it is enough to crush the can and throw it into a bag, but strict rules apply at collection points: aluminum and tin cans are accepted separately, and dirty or wet metal weighs more but costs less. For example, 1 kg of pure aluminum in 2026 is estimated on average at 120–150 rubles, while the polluted one is only 80–100 rubles. Proper preparation can save you up to 2–3 thousand rubles upon delivery of 50–100 kg of metal.

In the article you will find:

• 🔧 Step by step instructions for processing different types of cans (beer, canning, aerosol).
• ⚠️ List of dangers, which are not warned about at the reception points (torn edges, chemical residues).
• 📦 Comparison of packaging methods: bags, boxes, pressing - which is more profitable?
• 💰 Tips for increasing profits, including sorting by metal grade.

1. Which banks accept scrap metal: complete list

Not all empty cans are created equal. Reception points divide them into three main categories, on which the price depends:

• 🍺 Aluminum cans (from beer, soda, energy drinks) - the most expensive. Easily identified by their magnetic properties: they do not stick to a magnet.
• 🥫 Tin cans (canned food, paint, technical fluids) - cheaper than aluminum, but heavier. Sticks to a magnet.
• 🚫 Aerosol cans (from under deodorants, polyurethane foam) - accepted only empty and removed from the valve. Explosive!

Also distinguished bimetallic cans (for example, from condensed milk) - they are accepted as tin, but at a reduced price. And here are the cans from under oils, solvents or chemicals They often refuse to take it due to residues of hazardous substances. Before taking the test, check the rules on the reception site’s website - some require certificate of absence of toxic residues.

2. Preparing jars: cleaning and drying

Dirty or damp jars will lose up to 40% cost due to weight gain from debris and water. For example, 100 beer cans with residual liquid can “add” 2–3 kg of excess weight, which you will not be paid for. To avoid this:

1. Rinse the jars under running water using a brush or sponge. For canning jars with dried leftovers, soak them in warm water and baking soda (1 tablespoon per 1 liter) for 30 minutes.
2. Dry outdoors or in a well-ventilated area. Wet metal rusts faster, and rust reduces the price.
3. Remove labels. They can be soaked in water or scraped off with a knife. At some collection points, they pay 5–10% less for cans with stickers.

⚠️ Attention: Never burn leftover paint or oil in cans! When heated, toxic gases are released, and soot makes the metal unsuitable for recycling. Such cans are sent for recycling rather than melting.

3. Flattening cans: tools and safety precautions

Flattened cans occupy 5–7 times less space, which simplifies transportation and increases the volume of metal delivered in one trip. However, this must be done correctly so as not to get hurt or damage the jar (torn edges reduce the price).

Tool	Suitable for	Pros	Cons
Leg (advance)	Aluminum cans	Fast, no tools required	Rough edges, risk of slipping
Hammer	Tin and aluminum	Smooth flattening, force control	Noisy, requires skill
Can press	All types	Maximum sealing, safe	Expensive (from RUB 3,000), takes up space
Vise	Tin cans, spray cans	Smooth results, minimal effort	Needs to be fixed, inconvenient for large volumes

For aerosol cans flattening is strictly prohibited - they are only sold in their entirety with the valve previously removed (pierce a hole in the side wall to release the remaining gas).

Make sure the jar is empty and dry|

Wear gloves and closed-toe shoes|

Flatten on a flat, stable surface|

Do not point the can at yourself or other people|

For tin cans, use a hammer or vice-->

4. Can Sorting: Why It's Important

At scrap metal collection points, cans are weighed and valued according to three criteria:

1. Metal type (aluminum vs tin).
2. Cleanliness (presence of rust, paint, labels).
3. Form (flattened vs whole).

If you hand over everything in one pile, you will be paid minimum price - usually as if it were tough. Separate sorting increases profits by 20–50%. For example:

• 🍺 Aluminum cans (beer, cola) - 120–150 rub/kg.
• 🥫 Tin cans (canned food) - 30–50 rub/kg.
• 🔴 Painted cans (aerosols, paint) - 10–20 rub/kg (requires cleaning).

For convenience, use separate containers or labeled bags. Some collection points provide free sorting bags - check this in advance.

How to distinguish aluminum from tin without a magnet?

Aluminum cans are lighter than tin cans (the weight of an empty 0.5 liter can is about 14 g vs. 40–50 g for tin).

When struck, aluminum produces a duller sound, while tin produces a louder sound.

Aluminum does not rust; tin becomes covered with red spots when in contact with water.

5. Packaging cans: what to choose for transportation

Incorrect packaging may result in refusal of admission (if the cans fall apart) or injuries (cuts from sharp edges). Let's look at the pros and cons of each option:

• 📦 Cardboard boxes - suitable for flattened cans. They are cheap, but they get wet in the rain and tear when they weigh too much.
• 🎒 Thick bags (big bags) — the optimal choice for 50–100 kg. They cost from 200 rubles and can withstand up to 500 kg.
• 🔗 Wire bundles - used for whole cans. Saves space but takes time.
• 🚛 Pallets — for wholesale quantities (from 500 kg). Some reception centers provide them free of charge.

⚠️ Attention: If you use bags, choose polypropylene (labeling PP) - they do not tear due to sharp edges. Bags from PVD (low-density polyethylene) will pierce tin cans in 5 minutes.

For transportation in the trunk of a car, place cans flattened side downto avoid displacement. If you are carrying more than 100 kg, secure the load with ropes - during sudden braking, the bag can move and damage the car.

6. Where to hand over the cans: choosing a collection point

Scrap metal prices vary by region and company. In 2026, average prices in Russia:

Region	Aluminum (rub/kg)	Tin (rub/kg)	Painted metal (rub/kg)
Moscow and region	140–160	45–60	15–25
St. Petersburg	130–150	40–55	10–20
Regions (average)	100–130	30–45	5–15

To find a good deal:

1. Use price comparison services: Metallolom.ru, Lom.ru or 2GIS with the “scrap metal acceptance” filter.
2. Call and ask if they accept small scrap (banks) - some work only with large quantities (from 1 ton).
3. Ask about bonuses: some points give discounts on your next change or free delivery over 300 kg.

Avoid "black" acceptors without a license - they may underestimate weight (using uncertified scales) or pay "black cash" without documents. Legitimate companies issue receipt order indicating the weight and amount.

7. Common mistakes and how to avoid them

Even experienced scrap metal dealers lose money over small things. Here TOP-5 errors and their solutions:

• 🗑️ Unpeeled jars — food or paint residues increase the weight, but are not paid. Solution: wash the jars in a soda solution (100 g per 5 liters of water).
• 🧲 Mixing aluminum and tin — the price drops to the level of tin. Solution: use a magnet to sort.
• 🩹 Cuts from sharp edges — flattened cans with torn edges are accepted at a reduced price. Solution: flatten in a vice or press.
• 💧 Wet jars — they rust in 2–3 days, losing up to 30% of their value. Solution: dry in the sun or with a fan.
• 🚫 Aerosol cans with gas - may explode during pressing. Solution: puncture the hole and release the gas in advance.

Another common problem is underweight. To avoid being scammed:

• Weigh the jars at home on household scales (accuracy up to 100 g).
• Request the weighing to be repeated if the result seems suspicious.
• Hand over the metal in the presence of employees - some points “lose” part of the cargo during unloading.

FAQ: Answers to frequently asked questions

Can I recycle cans of paint or oil leftovers?

Banks with leftovers oils, paints or chemicals Not all items are accepted. Those that agree pay 2-3 times less due to the need for cleaning. It is better to air dry the jars for 2-3 days or rinse them with a solvent (for example, white spirit for oil cans). Some items require certificate of absence of hazardous substances - check in advance.

How many cans do you need to earn 1,000 rubles?

Depends on the type of cans and region. Approximate calculation for Moscow:

• 🍺 Aluminum cans (0.5 l): 1 can ≈ 14 g → 1 kg ≈ 70 cans. For 1,000 rub. you need ~5 kg (350 cans).
• 🥫 Tin cans (canned food): 1 can ≈ 100 g → 1 kg ≈ 10 cans. For 1,000 rub. you need ~20 kg (200 cans).

Tip: collect cans in offices, cafes or from neighbors - this way you will accumulate the required amount faster.

What to do with aerosol cans?

Aerosol cans are handed over only empty and with the valve removed. Algorithm:

1. Use the can all the way (press the nozzle until no more gas comes out).
2. Poke a hole in the side wall with a screwdriver (away from your face!).
3. Remove the valve with pliers.
4. You cannot flatten it - hand it in whole.

⚠️ Attention: Do not throw cans into a fire or puncture the valve - this may cause an explosion!

How to store jars until delivery so that they do not rust?

Optimal storage conditions:

• 🏠 Dry room (garage, storage room) with ventilation.
• 📦 Pallet or shelves — do not store jars on the ground (they absorb moisture).
• 🧂 Silica gel - Place desiccant bags in containers.
• 🔄 Regular inspection - check the jars for rust once a month.

If the cans are already rusty, clean them wire brush or soak in a vinegar solution (1:1 with water) for 10–15 minutes.

Is it profitable to buy a can press?

Abs pays off if you give in more than 200 kg of cans per month. Calculation example:

• Press cost: ~3,000 rub.
• Space saving: 1 bag (50 kg) of flattened cans vs 3 bags of whole ones.
• Time saving: flattening 100 cans by hand - 30 minutes, by press - 5 minutes.
• Extra Income: Some locations pay 5-10% more for neatly flattened cans.

For rare deliveries (once every six months), a hammer or vice is sufficient. If you collect scrap metal regularly, the press will pay for itself in 3-4 months.
