Aluminum is a lightweight, malleable that is metal often used as an alloy. Copper, manganese, magnesium and silicon are the most common aluminum alloys.
Recycling aluminum is very cost effective – the metal is simply separated into categories and then melted down. A sample is drawn from the metal to see if any adjustments need to be made before it is cast. Once this is done, the furnace is tapped and poured into moulds. After cooling, the recycled aluminum is stacked and sold to various industries for re-use.
This whole process requires only 5% of the energy needed to create new aluminum.
