Aluminum Riches Hidden in Soda Cans

How Much Aluminum is in 100 soda cans? Not just what do 100 empty soda cans weigh, but how much useful aluminum is there in these cans? There is a lot of paint and plastic that goes into a beverage can. A can without the aluminum is basically a fragile, thin plastic bag. That coating is totally necessary because aluminum is a very active metal. You can’t use the paint, or plastic liner coatings, as those will burn off in melting. Some metal oxidizes in the melting process. A lot of a can’s weight will end up as useless dross – the scum floating on the molten metal.
So how much of it is actually useful aluminum? – Take a look at this video to see the numbers I got.
