You finish a fizzy drink and drop the empty can into the recycling bin. That is not the end of the can's story. It is the start of a new one.
First, a truck collects the recycling and takes it to a sorting centre. There, machines separate the materials. A giant magnet pulls out steel cans. Aluminium cans (aluminum in the US) are not magnetic, so a different machine pushes them aside.
Next, the aluminium cans are squashed into huge blocks and taken to a factory. The cans are shredded into small pieces, cleaned, and melted in a furnace. The hot liquid metal is poured into moulds and cooled into long bars.
Then the bars are rolled out into thin sheets, like dough under a rolling pin. The sheets are cut and shaped into brand-new cans, filled with drinks, and sent to the shops. A recycled can can be back on a shelf in about sixty days.
Recycling aluminium is a big help to our planet. Making a can from old cans uses about 95 percent less energy than making one from new metal dug out of the ground. Aluminium can be recycled again and again without getting worse, so the can in your hand might once have been part of hundreds of other cans.
