摘要
铝的最大优点之一是可回收性强,可多次反复循环利用,每循环一次的损失只不过5%～20%,自1886年铝的商业化生产以来所生产的铝仍有约70%在使用。铝是一种储能式的金属,被称为储能银行,铝也是绿色金属,用它制造交通运输装备可显著减少温室气体排放,在发展低碳经济社会中铝将扮演着重要的作用。2020年全球铝工业可进入"负"碳轨迹时期,即交通运输业由于使用铝所排放的二氧化碳低于提取铝所排放的。
The most benefit of aluminum is multi-recycle ability. The loss is 5% to 20% per recycling. About 70% of the industrial aluminum produoed since 1886 till now still being recycling. Aluminum is an energy-saving metal and being called ＂energy-saving bank＂. It is called ＂green metal＂ as well. It can be used as construction materials for traffic vehicles, so as to reduce the emission of carbon. The ＂negative carbon period＂ should come at the year of 2020 and latter on the world. The carbon dioxide emission of aluminum used in traffic industry shall less than that for producing aluminum.
