Why do we recycle metal?                                                                                                                       

Steel and Aluminium exists in the large quantities throughout Australia. Their uses and usefulness were discovered hundreds, if not thousands of years ago. Longevity, malleability, strength and conductivity - their properties have been used over the ages to provide us with  the many goods we see today. they may be found in the items as varied as cars, computers, buildings and packaging. although consumption of steel has dropped since 1970's, aluminium use is still growing. Metals may remain for many years as viable products and so the environmental effects of their production will be lessened relative to using less durable materials.

World primary production of aluminium is around 24 million tonnes on average a yaer. The largest producer of aluminium is Australia, althoug other producer countries include Jamaica, Brazil, Guinea, China and parts of Europe. World crude steel production stood at over 1.1 billion tonnes in 2006. This represented a worldwide increase in production of over 9% campared to 2005. Excluding China, world production rose by 4.5% - 5% in 2006.

WHY BOTHER TO RECYCLE?

Metals can be recycled indefinitely without loosing any of their properties. They make up around 8% of the average household rubbish yet in 2006 the recycling rates for aluminium and ferrous metals as a percentage of their consumption were only 33% and 26% respectively.

Aluminium

Alumium is produced from bauxite, a clay-like  ore that is rich in aluminium compunds. The aluminium combined with oxygen. This alumina has to be stripped of its oxygen in order to free aluminium. the alumina is dissolved in a moten salt at a reduction plant and a powerful electric current is run through the liquid to separate the aluminium from oxygen. This process uses large quantities of energy. Recycling 1kg of Aluminium saves up to 6kg of bauxite, 4kg of chemical products and 14 kWh of electricity.

Recycling aluminium requires 5% of the energy and produces only 5% of the CO2 emissions as compared with primary production and reduces the waste going to landfill. Aluminium can be recycled indefinitely, as resprocessing does not damage its structure. Aluminium is also the most cost-effective material to recycle.

A recycled aluminium can saves enough energy to run a television for three hours
