Aluminium Can Recycling in Sweden – Facts and Environmental Impact

Aluminium cans are the backbone of Sweden's deposit system. With over a billion cans recycled annually, Sweden demonstrates how effective a well-designed return system can be. Here's what makes aluminium recycling so important — and so impressive.

Why Aluminium Recycling Matters

Aluminium is one of the most recyclable materials on the planet:

• Infinitely recyclable — aluminium never degrades in quality through recycling
• 95% energy savings — recycling aluminium uses 95% less energy than producing it from scratch
• 60-day turnaround — a recycled can can be back on store shelves in just 60 days
• Valuable material — aluminium retains significant economic value even after use

The Recycling Process

Step 1: Collection

When you return a can to a reverse vending machine, it's compacted and stored. Returpack collects these compacted cans from retailers across Sweden.

Step 2: Sorting

At processing facilities, cans are sorted using magnets and eddy current separators to remove any non-aluminium contaminants.

Step 3: Shredding

Sorted cans are shredded into small pieces, increasing surface area for efficient melting.

Step 4: De-coating

Paint, labels, and lacquer are removed through a controlled heating process.

Step 5: Melting

Shredded aluminium is melted in large furnaces at approximately 660°C. Impurities rise to the surface and are removed.

Step 6: Casting

Molten aluminium is poured into large ingots or rolled into sheets.

Step 7: Manufacturing

Aluminium sheets are stamped and formed into new cans, ready to be filled and sold.

Sweden's Aluminium Recycling Numbers

| Metric | Value | |---|---| | Cans sold annually | ~1.5 billion | | Return rate | ~86% | | Cans recycled annually | ~1.3 billion | | Energy saved annually | Equivalent to powering a small city | | CO₂ avoided annually | Tens of thousands of tonnes |

The Environmental Cost of NOT Recycling

When aluminium cans are not recycled, the consequences are significant:

• Bauxite mining — extracting aluminium ore destroys habitats and uses enormous water resources
• Smelting energy — producing new aluminium from ore requires vast amounts of electricity
• Carbon emissions — virgin aluminium production is one of the most energy-intensive industrial processes
• Landfill waste — aluminium takes 200–500 years to decompose in landfills

Fun Facts About Aluminium Cans

• The average aluminium can weighs just 15 grams
• Every minute, over 100,000 aluminium cans are recycled worldwide
• A stack of recycled cans the height of the Washington Monument would weigh about 3 tonnes
• Aluminium was once more expensive than gold (in the 1800s)
• The energy saved by recycling one can could power a TV for 3 hours

How PantDela Helps

Every can that doesn't make it to a reverse vending machine is a missed opportunity. PantDela ensures more cans enter the recycling stream:

• Givers post their available cans on PantDela
• Collectors pick them up and return them
• Result: more aluminium recycled, less waste, and income for collectors

If you have cans at home that you haven't gotten around to returning, share them on PantDela today. It takes just two minutes — and every can makes a difference.
