Aluminum Can Recycling

  • The aluminum can recycling rate for 1996 was 63.5%.

  • In 1996 the industry paid out $1.08 billion to recyclers for aluminum cans.

  • 62.8 billion cans were recycled in 1996.

  • It takes approximately 31 aluminum cans to make one pound.

  • It takes about 60 days for an aluminum can to be recycled, made into a new can, filled with a beverage, and back on your grocer's shelf.

  • It takes four pounds of bauxite to make one pound of aluminum, and all of it must be imported from other countries.

Aluminum comprises 10% of the average car's weight, but it represents 35 percent to 50 percent of the recycled material value.

A) SAFETY

All grades shall exclude:

1) pressurized closed or insufficiently open containers of all origins which could cause explosions. Containers shall be considered as insufficiently open where the opening is not visible or is less than 10 cm in any one direction.

2) dangerous material, inflammable or explosive, fire- arms (whole or in part), munitions, dirt or pollutants which may contain or emit substances dangerous to human health or to the environment or to the steel production process.

3) hazardous radioactive materials:

  • material presenting radioactivity in excess of the ambient level of radioactivity

  • radioactive material in sealed containers even if no significant exterior radioactivity is detectable due to shielding or due to the position of the sealed source in the scrap delivery.

B) STERILES (cleanliness)

All grades shall be free of all but negligible amounts of other non- ferrous metals and non- metallic materials, earth, insulation, excessive iron oxide in any form, except for nominal amounts of surface rust arising from outside storage of prepared scrap under normal atmospheric conditions.

All grades shall be free of all but negligible amounts of combustible non-metallic materials, including, but not limited to rubber, plastic, fabric, wood, oil, lubricants and other chemical or organic substances.

All scrap shall be free of larger pieces (brick- size) which are non-conductors of electricity such as tyres, pipes filled with cement, wood or concrete.

All grades shall be free of waste or of by- products arising from steel melting, heating, surface conditioning (including scarfing) grinding, sawing, welding and torch cutting operations, such as slag, mill scale, baghouse dust, grinder dust, and sludge.
