The natural raw materials are therefore made up of minerals such as bauxite from which aluminum is extracted after a long manufacturing process while, on the other hand, secondary raw materials are synonymous with scrap and that is all the waste material deriving from scraps of processing, mouthpieces, scraps and old artifacts that have disappeared from the scene due to obsolescence or senescence. The aluminum industry therefore obtains its raw materials from two sources: one primary and the other secondary. The primary one is powered by bauxite, which is processed to become aluminum oxide, from which the metal is extracted by means of electrolysis (primary aluminum). Recycling aluminum saves 95% of the energy required to produce it starting from the raw material. In fact, to obtain 1 kg of aluminum from bauxite, 14 kWh are required, while to obtain 1 kg of new aluminum from the used one, 0.7 kWh is needed. The aluminum obtained is called secondary aluminum. Aluminum recycling in Italy is a very important activity for the economy. Basti pensare che non abbiamo importanti miniere di bauxite e che l’energia elettrica da noi è la più cara d’Europa. La produzione italiana di alluminio secondario è ormai vicina alle 400.000 t/anno, mentre quelle di alluminio primario supera di poco le 220.000 t/anno. Il riciclaggio dell’alluminio é necessario e sensato; infatti esso non comporta solo dei vantaggi per i consumatori, i comuni e l’industria; la riduzione dell’estrazione della bauxite è anche un prezioso contributo alla salvaguardia dell’ambiente La raccolta di alluminio viene effettuata in moltissimi comuni attraverso, idonei contenitori posizionati lungo le strade o presso centri creati appositamente. In diverse località vengono organizzate azioni di raccolta supplementari. Another possibility is that of the RAIL Consortium (Aluminum Recovery in the form of a can) which supports consumers sensitive to ecological problems. Metalrecuperi Srl Imp.
