INTRODUCTION
The metal that can be recycled over and over again and in turn saves energy and natural resources – Aluminium, is silver and soft metal which belongs to the 13th group and is a part of p – block elements.
It was first isolated by Friedrich Wohler in 1827 and then named by Humphry Davy in 1807.
The atomic number of Aluminium is 13 and it has electronic configuration – [Ne] 3s² 3p¹.
HISTORY
Aluminium salts was used by Greeks for dyeing and dressing wounds in ancient times. Later on, Hans Christian Orsted produced an impure form of Aluminium in the year 1825. Further, Pierre Berthier discovered the metal Aluminium in bauxite ore.
FACT : In the late 19th century aluminium became more valuable than gold.

FACT : On replacing a few Aluminium ions by chromium ions in Aluminium oxide, ruby gemstones can be obtained.
RECYCLING
Theoritically, Aluminium is said to be 100%recyclable without losing its natural qualities. Until 1960s, recycling was a low profile activity but the growing use of Aluminium cans has now seen the setup of aluminum recycling industries.
Recycling aluminium includes simple steps from melting the scrap (requires really less energy) to extracting aluminium.
The secondary aluminium that is obtained after recycling is said to maintain the same physical properties as primary aluminium.
FACT : Recycling one aluminium can saves enough energy that can be used to run the television for 3 hours.
HEALTH CONCERNS
Aluminium, till date, is seen to have no known function in biology. Aluminium salts are observed to be non – toxic or can also be said to have very low toxicity.
Acute toxicity is traced when it deposits on bone and central nervous system which in turn reduces the renal function of the patient. High dosage of aluminium leads to neurotoxicity and osteopenia.
Aluminium has controversially been stated to be one of the factors in Alzheimer’s
