PROFILES IN GARBAGE:Aluminum Packaging

1.97 million tons or 0.9% by weight.*

1.59 million tons of cans per year.*

380,000 tons of foil per year.*

14.44 pounds per person per year.*

11.63 pounds of cans and 2.81 pounds of foil per person per year.*

101 billion cans or 370 per person were used in 1999.

1 can weighs less than 0.03 pounds.

Recycling Rate:

870,000 tons or 44.2%.*

840,000 tons or 54.5% for cans.*

950,000 tons or 62.1% for cans in 2000 (industry data).

30,000 tons or 7.9% for foil.*

Recycled Content:

51% for cans in 2000 (industry data).

Incinerated or Landfilled:

1.1 million tons or 0.7% of discarded MSW by weight.*

750,000 tons of cans and 350,000 tons of foil.*

Aluminum is noncombustible and can end up as a residue in incinerator ash.

Landfill Volume:

6.5 million cubic yards or 1.6% of landfilled MSW in 1997.

5.3 million cubic yards of cans and 1.2 million cubic yards of foil in 1997.

Density:

Landfilled cans weigh 250 pounds per cubic yard (lbs/cu. yd).*

Landfilled foil weighs 550 lbs/cu. yd.*

Loose cans have a density of 50 lbs/cu. yd to 74 lbs/cu. yd.

Flattened cans have a density of 250 lbs/cu. yd.

Source Reduction:

In 1972, 21.75 cans weighed 1 lb.

In 2000, 33.12 cans weighed 1 lb.

Recycling Markets:

Aluminum can sheet manufacturers are the primary market for used aluminum cans. Foil usually is bought by the same markets.

End-Market Specifications:

ISRI guidelines for nonferrous scrap: NF-98. “Old can stock” specs include non-beverage cans. “Shredded,” “densified,” “baled” and “briquetted” specs exclude non-beverage cans.

Contaminants include dirt, moisture, plastic, glass and other metals. Lead is a problem. A magnet will separate steel cans from aluminum, but other contaminants are more difficult to spot.

Foil markets generally want clean, dry foil. Because foil and cans use different alloys, they will contaminate each other in the recycling process.
