Abstract

Završni rad obrađuje temu kružnog gospodarstva s naglaskom na ulogu metalurgije i recikliranja aluminijske ambalaže u kružnom gospodarstvu.
U prvom dijelu dan je pregled ekonomskih, ekoloških i drugih aspekata vezanih uz recikliranje aluminijskih proizvoda, ali i na smanjenje ovisnosti o ograničenim prirodnim resursima. Naglasak je stavljen na aluminijske limenke, jer čine većinu oporabljenih aluminijskih proizvoda, a njihovim recikliranjem postiže se izuzetno kvalitetna talina aluminija kao osnova za formiranje gotovih proizvoda lijevanjem ili novih legura daljnjom obradom taline.
U drugom dijelu rada opisuje se dobar primjer prakse u recikliranju aluminijskih limenki. U dvije odvojene faze prerade ispitana su mehanička svojstva, kemijski sastav i strukturna analiza ostvarenih talina. Navedenim ispitivanjima utvrđeno je da recikliranjem aluminijskih limenki, pored izuzetno pozitivnih ekonomskih i ekoloških pokazatelja, dobivamo veoma čist aluminij, upotrebljiv kao dezoksidans u proizvodnji čelika, ali i kao odličnu sirovinu za proizvodnju novih aluminijskih legura.

Abstract (english)

The final paper deals with the topic of the circular economy with an emphasis on the role of metallurgy and recycling of aluminum packaging in the circular economy.
In the first part, there is an overview of economic, ecological and other aspects related to the recycling of aluminum products, but also on the reduction of dependence on limited natural resources. Emphasis is placed on aluminum cans, because they make up the majority of recycled aluminum products, and their recycling results in an extremely high-quality aluminum melt as the basis for the formation of finished products by casting, or development of new alloys by further processing of the melt.
In the second part of this final paper, a good example of practice in recycling aluminum cans is described. In two separate stages of processing, the mechanical properties, chemical composition and structural analysis of the resulting melts were tested.
The above mentioned experiments have concluded that by recycling aluminum cans, in addition to extremely positive economic and ecological indicators, we obtain very pure aluminum, which can be used as a deoxidizer in the production of steel, but also as an excellent raw material for production of new aluminum alloys.
