Abstract. During many technological processes there is exploitation of resources, generation of waste materials and energy loss, bringing about the degradation of the environment. The importance of the rational usage of matter and energy requires the development of methods of technological systems’ risk assessment and the analysis of their impact on the environment. One method, based on the exergetic analysis, is ELCA analysis. Since the irreversibility of the system is the most suitable parameter of the resource exploitation, and is defined by the exergetic loss, this method gives a clear picture of the influences of the technological systems on the environment. In order to stimulate and use renewable resources one must define exergetic-ecological-economic parameters, so that the requirements of clean technologies would be met.
Key Words: Exergetic Analysis, Risk, Technological Systems, Environmental Protection

PRIMENA EKSERGETSKE ANALIZE U ANALIZI RIZIKA TEHNOLOŠKIH SISTEMA I ZAŠTITI ŽIVOTNE SREDINE
Pri mnogim tehnološkim procesima dolazi do eksploatacije resursa, stvaranja otpadnih materija i energetskih gubitaka, što dovodi do degradacije životne sredine. Značaj racionalnog korišćenja materije i energije iziskuje razvoj metoda procene rizika tehnoloških sistema, kao i analizu njihovog uticaja na životnu sredinu. Jedna od metoda, bazirana na eksergetskoj analizi, je ELCA analiza. Kako je nepovratnost sistema najprikladniji parametar eksploatacije resursa, a definisana je upravo eksergetskim gubicima, ova metoda daje jasnu sliku o uticaju tehnoloških sistema na životnu sredinu. U cilju stimulacije i korišćenja obnovljivih resursa potrebno je defini-sati i eksergetsko-ekološko-ekonomske parametre, kako bi se ostvarili zahtevi čistih tehnologija.
