Aluminum, or aluminum, which we call it in Australia, an extremely useful metal. While aluminium is not short delivery-it is the most abundant metal in the Earth's crust-is a resource-intensive process required to submit a form that we can use.
Compared with most other metals, aluminium is extremely difficult to extract from its ore, bauxite is called. It takes approximately 4-5 tonnes of high grade bauxite ore to produce one tonne of aluminum.It means a lot of digging and land degradation and lots of energy and all of the emissions associated with this activity.
Another important environmental issue in the production of aluminum is the emission of perfluorcarbons (PFC), a powerful greenhouse gas which remain * permanent * once released into the atmosphere.
