why is it gd and what are common aluminium compounds??? thx
It's quite expensive to make aluminum, whereas it's quite cheap to melt it down and reuse it.
Where aluminium is the third most common element on the planet (after oxygen and hydrogen), it is also the most used element on the planet, everything from pull tabs on soda cans to girders used in construction. Car parts, dog tags, pots and pans, it is everywhere. 95% of aluminium survives recycling, so when you recycle 1,000 can's (or return for deposit in 13 states), it is back on the shelves in the form of 950 new cans in just 6 weeks. As aluminium is a very difficult metal to seprate from other ores such as bauxite, recycling both protects the enviroment by slowing mining, and stabelizing the economy. Its not just a win-win, it can also be quite profitable even with the current low prices for aluminium on the markets.
