Abstract:Kobalt se nahaja na evropskem seznamu kritičnih surovin in je pomemben material pri razvoju modernih tehnologij ter zelenih industrij. Slovenija nima rudnikov kobalta in obratov za rafiniranje, zato je visoko odvisna od uvoza. Namen magistrske naloge je podati opis stanja, o tokovih kobalta v Slovenji, v obdobju petih let (od leta 2020, do vključno leta 2024) in podati oceno okoljskih vplivov tipičnega izdelka iz kobalta (trajnega Samarij Kobalt magneta). Podatke o tokovih smo zbirali v podatkovni bazi Comtrade, za analizo življenjskega cikla (angl. Life Cycle Assessment; v nadaljevanju: LCA) pa smo uporabili orodje Open LCA, s podatkovno bazo Ecoinvent 3.8. V rezultatih smo na grafih, modelih in tabelah prikazali trenutno stanje tokov kobalta v Sloveniji in podali oceno okoljskih vplivov. Rezultati so pokazali, da je Slovenija izrazito uvozno odvisna, pri čemer se večina uvoženega materiala kopiči v zalogah ali ostane v domači rabi. Kažejo se jasne priložnosti za vzpostavitev domačih reciklažnih in predelovalnih zmogljivosti, zlasti zaradi naraščajočega uvoza odpadkov in upada njihovega izvoza. Analiza življenjskega cikla dodatno potrjuje koristi takšnega prehoda, saj recikliranje Samarij Kobalt magnetov, v vseh opazovanih vplivnih kategorijah, pomembno zmanjša vplive in tako podpira strateški premik h krožnemu gospodarstvu ter zmanjšanju odvisnosti od primarnih surovin.

Title:Material flow analysis and life cycle assessment of cobalt in Slovenia
Abstract:Cobalt is on the European list of critical raw materials and is an important material in the development of modern technologies and green industries. Slovenia has no cobalt mines or refining plants, so it is highly dependent on imports. The purpose of this master's thesis is to describe the situation regarding cobalt flows in Slovenia over a five year period (from 2020 to 2024) and to assess the environmental impact of a typical cobalt product (a permanent samarium cobalt magnet). We collected data on flows in the Comtrade database, and for the life cycle assessment (hereafter: LCA) we used the Open LCA tool with the Ecoinvent 3.8 database. In the results, we presented the current state of cobalt flows in Slovenia in graphs, models, and tables and provided an assessment of environmental impacts. The results showed that Slovenia is highly dependent on imports, with most of the imported material accumulating in stocks or remaining in domestic use. There are clear opportunities for establishing domestic recycling and processing capacities, particularly due to the increasing import of waste and the decline in its export. Life cycle assessment further confirms the benefits of such a transition, as recycling samarium cobalt magnets significantly reduces impacts in all observed impact categories, thus supporting the strategic shift towards a circular economy and reducing dependence on primary raw materials.
