The analysis of possible treatments for residual mixed municipal waste and analysis of chosen treatments are presented. The chosen treatments are analysed from the principles of sustainable development. On the basis of comparative analysis, a proposition of preferential procedure is suggested. The chosen treatments are analyseli and compared from the environmental point of view and also from economic and sociological point of view. The treatment process recently suggested by Snaga is also taken into considoration. The analyses, which are presented in this paper, were made completely separately from those made by Snaga. The proposition of preferential treatment consists of sorting-out the recyclables, mechanical separatian of the lighter, caloric fraction to be usod as a solid recovered fuel, whereas the residual heavy fraction (which contains the concentrated biodegradable components) is prepored and utilised in on anaerobic digestion with the production of biogas and the dehydration of the sludge before disposalZaradi zahtev zakonodaje po trajnostnem ravnanju z odpadki in vedno težjega in dražjega zagotavljanja površin za odlaganje odpadkov je v ljubljanski regiji predvidena MBO (mehansko-biološka obdelava) preostalih mešanih komunalnih odpadkov. Prikazani so poglavitni možni postopki za obdelavo preostalih mešanih komunallnih odpadkov in analiza izbranih postopkov na osnovi načel trajnostnega ravnanja ter predlagan prednostni postopek, izbran na osnovi primerjalne analize. Izbrani postopki so analizirani in med sabo primerjani z okoljskega, ekonomskega in sociološkega vidika, v primerjavo pa je vključen tudi postopek, ki ga predlaga Snaga (Snaga Javno podjetje, d.o.o., Ljubljana), saj so bile v tem delu prikazane analize izdelane povsem ločeno od analiz Snage. Predlagani prednostni postopek je sestavljen iz izločanja sekundarnih surovin in mehanske separacije lahke, energetsko bogate frakcije kot surovine za pripravo trdnega goriva, separacije težje frakcije, ki vsebuje koncentrirane organske biorazgradljive snovi in njene priprave za anaerobno fermentacijo, anaerobne fermentacije s proizvodnjo in energetsko izrabo bioplina ter dehidracije pregnitega blata pred končno oskrboTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza društev gradbenih inženirjev in tehnikov Slovenije
