Abstract

Potencijalne utjecaje sustava gospodarenja na okoliš moguće je procijeniti upotrebom metodologije životnog ciklusa (LCA, Life cycle assessment) pri čemu se sustavno sagledavaju mogući utjecaji na okoliš svih proizvoda, procesa i aktivnosti na način da se identificiraju, kvantificiraju i vrednuju ukupni utrošeni resursi kao i sve emisije te otpad koji pri tome nastaje. U sklopu ovog istraživanja, na primjeru Grada Zagreba, napravljena je detaljna analiza mogućih koncepata gospodarenja otpadom. Prihvatljivi koncepti vrednovani su primjenom metodologije analize životnog ciklusa s ciljem određivanja najpovoljnijeg koncepta. Također, analizirani su i određeni podsustavi s ciljem određivanja pod kojim uvjetima pojedini procesi postaju povoljniji te su predložena odgovarajuća unaprjeđenja sustava odvojenog prikupljanja otpada. Dobiveni rezultati pokazuju da se ostvarenjem ključnog zaokreta u smislu prelaska s linearnog na kružno gospodarstvo ostvaruju bitni pozitivni efekti na okolišne značajke sustava gospodarenja otpadom, primarno zbog reciklaže iskoristivog otpada te smanjenja odloženih količina neobrađenog miješanog komunalnog otpada. Na primjeru različitih metoda biološke obrade otpada napravljena je analiza odgovarajućih podsustava koja je pokazala da obrada biootpada postupkom anaerobne digestije daje bolje rezultate od postupka kompostiranja kako u smislu utjecaja na okoliš tako i u energetskom smislu.

Abstract (english)

Life cycle assessment (LCA) is a general methodological framework introduced to assess all the environmental impacts related to the product, process or activity by identifying, quantifying and evaluating the overall resources consumed as well as all the emissions and wastes released into the environment. As a part of this research, detailed analysis of the different waste management systems in the City of Zagreb was performed. In order to determine the most appropriate waste management system, acceptable scenarios were assessed using LCA methodology. Furthermore, different subsystems were analyzed in order to determine the conditions under which the individual processes become more favorable. Also, certain improvements of source separation of household waste were proposed. The results shows that major turn of municipal solid waste management system from linear to circular economy has obvious positive effects on environmental performance of the system, primarily due to increased recycling of reusable waste and reduced landfilling of untreated mixed municipal waste. Different methods of bio-waste treatment were considered and the results shows that anaerobic digestion process performs better than composting in terms of environmental performance and overall energy produced.
