Aluminum Recycling

Aluminum is everywhere in our daily life. The recycling of aluminum becomes very important to save energy and prevent pollution. Recycle waste aluminum into new aluminum products can reduce 95% air pollution and 71% energy consumption compared from making new aluminum from bauxite ore. Actually the aluminum is a kind of perfect recyclable material because it is 100% recyclable.

In the U.S., the aluminum recycling already exceeded 50% in the 1980’s, and 62.1% in 2000. In 2004, Americans has recycled enough aluminum to build thirteen aircraft carriers. Every three months, Americans discard enough aluminum to completely rebuild every single commercial airplane in America. In Japan, the recycling of aluminum rate is also very high. It has already reached 43% in 1990, and as high as 83% in 2001.

Many people must do not know that the energy saving by recycling an aluminum can will run a TV for three hours, and that it needs about 400 years for aluminum to break down naturally if do not recycle.

From recycling a waste aluminum can into a new can, it only takes 60 days. Within this short period, a drink can from the grocery’s shelf to consumer’s hands, then turn to recycling plant being melted into aluminum plate and then made into a new can. The physical property is the same as before because the aluminum’s quality will not downgrade during recycling, so aluminum recycling is an ideal recycling material.

Here are some main procedures for aluminum recycling process.
1)       Aluminum products like aluminum cans, aluminum extrusion etc. are compressed into dense bales by baling machine, which can reduce transportation, storage and handling cost. Usually vertical hydraulic baler with large pressure force above 100T is a proper choice for pressing aluminum products (e.g. Sinobaler aluminum baling press machine Model SVB2-T-1200). After this, transport the waste aluminum to recycling plant.
2)       Sort the waste aluminum for confirming the end-use and treatment process.
3)       Shredding the aluminum into small pieces by heavy duty shredder.
4)       Removing the coating or paint on the aluminum surface.
5)       Melting.
6)       Aluminum casting.

As you can see, aluminum recycling is great for environment and saving energy. When you are going to discard a drink can, please think - Recycle it instead of discarding it.
