Aluminum could be recycled using the process found in Figure 6.2. Aluminum recycling provides many advantages [13]:Compared to producing aluminum from raw materials, recycling aluminum uses 95% less energy.In addition, 97% of the greenhouse gas emissions produced in primary production are diminished.Approximately nine tons of CO2 emissions are saved for every ton of aluminum recycled. Four tons of bauxite, which is used to produce aluminum, are saved. One thousand kilograms of CO2 are equal to driving over 5600 km.There is a permanent supply of the metal. The material is totally recyclable forever, so every time it enters the recycling loop, carbon emissions diminish.It is 20 times more energy efficient to produce aluminum cans from recycled metal instead of utilizing primitive metal.After recycling empty drink cans, brand-new cans can be sold within 60 days.

Aluminum recycling is a relatively simple operation: recovered cans are shredded, melted, cast into ingot, rolled into can sheet, and transformed back into cans. It can take as little as six weeks for an aluminum can to be manufactured, used, and recycled back into an aluminum can.

Aluminium production in Europe represents about 15–20% of world’s total production, being near 50% the contribution of secondary sources. Although recycling of aluminium in Europe is continuously growing, Europe is a net exporter of scrap due to several reasons namely the high energy prices. In terms of energy efficiency, aluminium recycling is strongly advisable since provides savings in energy near 95% when compared with extraction from primary sources.

An attractive alternative to composites materials in marine applications is that of all-metal sandwich structures, and in particular that of aluminium sandwich structures with cellular cores. Aluminium is recognised as a sustainable and versatile material (Mahfoud and Emadi 2010) due to its recyclability. In addition, aluminium recycling offers promising perspectives considering that the direct energy use in the production of recycled (secondary) aluminium is decreased by 93% in comparison to that required to produce primary aluminium (Schlesinger 2014).
