Abstract:	Zaradi pomanjkanja surovin, težav pri dobavi električne energije, geopolitičnih tveganj in volatilnosti cen, se vse bolj kažejo potrebe po drugačnem pristopu do proizvodnje in potrošnje dobrin. V magistrski nalogi tako preučujemo trajnostno gospodarjenje z viri, tako obnovljivimi, kot tudi neobnovljivimi ter gospodarjenje s kritičnimi surovinami. Nizkoogljične tehnologije, globalna digitalizacija poslovanja in prehod na zeleno gospodarstvo bodo po predvidevanjih strokovnjakov zahtevali še več virov, zlasti nekaterih kovinskih materialov. Zaloga neobnovljivih virov, kamor sodijo tudi rude, je končna in če jih bomo želeli ohraniti za prihodnje generacije, bo potrebno z njimi ravnati trajnostno. Pomanjkanje virov pomeni zamujene poslovne priložnosti, še posebej, ko gre za kritične surovine. Kot kritična surovina je bil v letu 2020 prepoznan tudi mineral boksit, iz katerega pridobivamo primarni aluminij. V magistrskem delu smo analizirali materialne tokove aluminija v Sloveniji in zbrali podatke o razpoložljivosti materiala za reciklažo oz. nadaljnjo transformacijo. Ugotavljamo, da je reciklaža aluminija bolj konkurenčna kot primarna proizvodnja, saj se poraba surovinskih in energijskih virov zmanjšuje z višanjem deleža uporabe recikliranega aluminija, na tak način pa je manjša tudi količina emisij v zrak. Na proizvodnjo aluminija iz sekundarnih virov bi se bilo smiselno usmeriti tudi zaradi rasti cen energentov ter zaostrenih pogojev na trgu zaradi vojne v Ukrajini, saj oboje dodatno vpliva na podražitev primarne proizvodnje aluminija in njegovega uvoza. Aluminij z reciklažo ne izgubi svojih lastnosti, zato ga je mogoče neomejeno reciklirati, kar se odraža tudi v nižjih stroških proizvodnje aluminija. Ker se z recikliranjem aluminij vrača neposredno v gospodarstvo, se zmanjšuje tudi uvozna odvisnost gospodarstva. Menimo, da v Sloveniji obstaja ekonomsko sprejemljiv potencial za proizvodnjo aluminija iz sekundarnih virov, saj je potrošnja višja od proizvodnje, prav tako pa uvoz aluminija in aluminijevih izdelkov iz leta v leto naraščata.

Title:	Material flow analysis of aluminium in Slovenia and its role for circular economy
Abstract:	Due to the lack of raw materials, problems in the supply of electricity, geopolitical risks and price volatility, the need for a different approach to the production and consumption of goods is becoming increasingly evident. In the Master's thesis, we thus ensure the sustainable management of resources, both renewable and non-renewable, as well as the management of critical raw materials. According to experts, low-carbon technologies, the global digitization of business and the transition to a green economy will require even more resources, especially some metal materials. The stock of non-renewable resources, which includes ores, is finite and if we want to preserve them for future generations, they must be managed sustainably. Resource scarcity means missed business opportunities, especially when critical raw materials are involved. In 2020, the mineral bauxite, from which primary aluminum is obtained, was also recognized as a critical raw material. In the master's thesis, we analyzed material flows of aluminum in Slovenia and collected data on available materials for recycling or further transformation. We find that aluminum recycling is more competitive than primary production, as the amount of raw material and energy resources is consumed by increasing the proportion of recycled aluminum used, and in this way, the emissions to the air are also lower. It would also make sense to focus on the extraction of aluminum from secondary sources due to the rise in the prices of energy products and the tough conditions on the market due to the war in Ukraine, as both have an additional effect on the promotion of primary production and its import. Aluminum does not lose its properties through recycling, so it can be recycled indefinitely, which is also reflected in cost savings. Since it returns directly to the economy through recycling, its import dependence is also taken into account. We believe that there is an economically acceptable potential for production of aluminum from secondary sources in Slovenia, as consumption is higher than production, and the import of aluminum and aluminum products is also increasing from year to year.
