Abstract

V magistrskem delu smo obravnavali problem povečevanja količine odpadkov v lokalnih skupnostih ter po svetu, kar je posledica hitre rasti prebivalstva. Odpadki se kopičijo, za njihovo pospešeno odstranjevanje pa se uporabljajo tehnike, ki še dodatno obremenjujejo okolje. Informacije, predstavljene v nalogi smo analizirali s pomočjo predhodnega pridobivanja relavantnih in zanesljivih podatkov. Predstavili smo trenutno najpogosteje uporabljene metode ravnanja z odpadki ter raziskali in analizirali novejše in naprednejše, ki ob enem spodbujajo razogličenje družbe. Pripravili smo detajlni pregled obstoječih naprav za pretvorbo odpadkov v bioplin ter biometan s pomočjo nadgradnje, v Sloveniji, Evropi in po svetu ter analizirali in primerjali nacionalne energetske podnebne načrte izbranih držav članic Evropske Unije, ki imajo ambiciozne načrte v smeri razogličenja družbe in uvajanja ali pa uporabe že obstoječih naprav za pridobivanje bioplina. Ugotovili smo, da imata najbolj ambiciozne cilje na področju pridobivanja plina iz odpadkov Avstrija in Danska, med obravnavanimi državami pa najbolj zaostaja Švedska. Število naprav za predelavo odpadkov v bioplin se iz leta v leto povečuje, naprave, ki za predelavo oziroma odstranjevanje uporabljajo za okolje obremenjujoče postopke pa so v fazi zapiranja ali zmanjševanja obratovanja. Največ naprav na letnem nivoju predela od 10000 do 20000 ton odpadkov v bioplin.

Secondary title:	Process systems in anaerobic digestion and waste treatment
Secondary abstract:	In this master's thesis we discussed the problem of increasing quantities of waste in local communities around the world, as a direct consequence of increasing growth of population. Waste material is accumulating around the world and its disposal requires the usage of techniques, that put additional strain on the environment. Information that is presented in this work was analyzed with the help of previously acquired relevant and reliable data. We presented the current most common methods of waste management and additionally explored and analyzed novel and advanced methods, that promote the transition into carbonfree society. We prepared a detailed review of current treatment plants that enable the conversion of waste into biogas or, with additional upgrades, into biomethane that are in use in Slovenia, Europe and other places around the world. Additionally, we compared the national energy and climate plans of selected member states of European Union, that employ ambitious strategies for transition into carbon-free society and adoption or usage of existing installations for production of biogas. We found out that Austria and Denmark have the most ambitious targets in the field of waste to gas production, with Sweden lagging behind the most. The number of installations that enable treatment of waste material into biogas is increasing every year. Simultaneously, installations that achieve that same goal with procedures that put additional strain on the environment are slowly being phased out or used in smaller capacities. Most treatment plants annually process from 10000 to 20000 tons of waste into biogas.
