The Republic of Serbia as a candidate country for the EU is obliged to comply with EU directives. This refers to the waste management sector as well. Different goals need to be fulfilled and the current waste management practice has to be improved in order to meet all regulatory EU requirements. Therefore, any piece of information that would support future waste management decisions is of great significance for developing and streamlining future strategies. The life cycle assessment (LCA) is a popular tool widely used for assessment of environmental impacts of waste management systems. This paper focuses on a LCA of four waste management scenarios used in selected region in Serbia (South Backa) and five indicators for the comparison and evaluation of municipal solid waste management strategies. The analysis includes the current situation of waste management in this region, as the base scenario, and three alternative scenarios. The combined life cycle inventory (LCI) model and life cycle impact assessment (LCIA) method has been used to evaluate the municipal solid waste system with the purpose of identifying environmental benefits and disadvantages, as well as economic cost of defined scenarios of waste management systems that could be implemented. The results clearly indicate the difference between the scenarios and show the influence of implementation of composting, RDF treatment, incineration and increased recycling rates on the environmental performance and economic cost of municipal solid waste management in the South Backa region.

IZVOD -Republika Srbija je, kao zemlja kandidat za ĉlanstvo u Evropskoj uniji, u obavezi da implementira zakonodavstvo EU u domaće zakonodavstvo, što se neminovno odnosi i na sektor otpada. S tim u vezi, Republika Srbija treba da unapredi sektor upravljanja otpadom, kako bi u potpunosti zadovoljila ciljeve EU u ovoj oblasti. Za razvoj i unapreĊenje buduće strategije upravljanja otpadom i pospešivanje procesa donošenja odluka u sektoru otpada, neophodna je primena novih alata. Za poreĊenje i evaluaciju razliĉitih strategija upravljanja otpadom u regionu, moguće je primeniti kombinaciju IWM-2 modela i Impact2002+ metodologije. IWM-2 model podrazumeva drugu fazu (inventar ţivotnog ciklusa, eng. life cycle inventory-LCI), a Impact2002+ treću fazu (ocenjivanje uticaja ţivotnog ciklusa, eng. life cycle impact assessment-LCIA) ocenjivanja ţivotnog ciklusa (eng. Life Cycle Assessment-LCA) ĉija je procedura definisana standardom ISO 14040. U ovom radu je kombinacija IWM-2 modela i Impact 2002+ metodologije primenjena na Juţno-baĉki region za upravljanje otpadom, da bi se procenilo kako će poboljšanje sistema upravljanja otpadom u navedenom Regionu uticati na ţivotnu sredinu, potrošnju energije i troškove upravljanja otpadom. Razvijen je scenario koji odraţava sadašnje stanje i alternativni scenario koji ukljuĉuje tehnologije upravljanja otpadom, neophodne da bi se ispunili minimalni zahtevi EU uz pristupaĉne troškove. Dobijeni rezultati jasno ukazuju kako će implementacija kompostiranja, povećanje stope recikliranja i odlaganje otpada na sanitarnu deponiju imati pozitivan uticaj na karakteristike ţivotne sredine u Juţno-baĉkom regionu.Ključne reči: komunalni otpad, sistem upravljanja otpadom, ocenjivanje ţivotnog ciklusa ABSTRACT -Republic of Serbia as a candidate for the EU is obliged to comply with EU directives.

Thus informations to support future waste management decisions can be very important in developing and streamlining future strategies. The combination of IWM-2 model and Impact2002+ methodology is a base comparison and evaluation of different municipal solid waste management strategies in Serbia. The IWM-2 model involves the second stage (life cycle inventory-LCI) and Impact2002+ third stage (life cycle impact assessment-LCIA) of the Life Cycle Assessment-LCA procedure defined in ISO 14040.
