Puppy With A Beverage Can

An empty aluminium can weighs approximately half an ounce (15 g). There are roughly 30 empty aluminium cans to a pound or 70 to a kilogram.
In many parts of the world a deposit can be recovered by turning in empty plastic, glass, and aluminium containers. Scrap metal dealers often purchase aluminium cans in bulk, even when deposits are not offered. Aluminium is one of the most cost-effective materials to recycle. When recycled without other metals being mixed in, the can–lid combination is perfect for producing new stock for the main part of the can – the loss of magnesium during melting is made up for by the high magnesium content of the lid. Also, reducing ores such as bauxite into aluminium requires large amounts of electricity, making recycling cheaper than producing new metal.
Many consumers find the taste of a drink from a can to be different from fountain drinks and those from plastic or glass bottles. In addition, some people believe that aluminium leaching into the fluid contained inside can be dangerous to the drinker's health. Scientific consensus is that aluminium plays no role in the development of Alzheimer's disease.
Aluminium cans often contain an internal coating to protect the aluminium from beverage corrosion. Despite this coating, trace amounts of aluminium can be degraded into the liquid, the amount depending on factors such as storage temperature and liquid composition. Chemical compounds used in the internal coating of the can include types of epoxy resin.
