Steel is completely recyclable, possesses great durability, and, compared to other materials, requires relatively low amounts of energy to produce. Innovative lightweight 

steels (such as those used in in automobiles and buidlings) help to save energy and resources. The steel industry has made immense efforts to limit environmental 

pollution in the last decades. Producing one tonne of steel today requires just 40% of the energy it did in 1960. Dust emissions have been reduced by even more.
