Poređenje uticaja životnog ciklusa polietilenske ambalaže različitih zapremina na životnu sredinu
Comparison of life cycle assessment for different volume polyethylene packaging on the environment
Projekat: Unapređenje i razvoj higijenskih i tehnoloških postupaka u proizvodnji namirnica životinjskog porekla u cilju dobijanja kvalitetnih i bezbednih proizvoda konkurentnih na svetskom tržištu (MPNTR - 46009)
Sažetak
U ovom radu je ispitan uticaj polietilenskih tuba različitih zapremina: 30 mL i 100 mL na životnu sredinu,upotrebom alata za analizu uticaja životnog ciklusa. Prikupljeni su podaci o vrstama i količini materijalnih i energetskih resursa koji se koriste u procesu pakovanja i distribucije i ovi podaci su uvršteni u softver GaBi 5. Ukupni maseni inventar životnog ciklusa je bio značajno niži za ambalažu manje zapremine. Razlaganjem ukupnog inventara na pojedine tokove, uočeno je da su u oba životna ciklusa (polietilenske tube od 30 mL i 100 mL) najveći udeo u ukupnom inventaru imali tokovi potrošnje sveže vode, emisije neorganskih elemenata u vazduh i zagađenje sveže vode otpadnim vodotokovima. Najveći doprinos svim navedenim tokovima za ambalažu obe ispitivane zapremine je pokazao proces proizvodnje i potrošnje dizel goriva. Rezultati ovog rada pokazuju da,u analiziranom slučaju, manji negativni uticaj na životnu sredinu ima ambalaža veće zapremine.
Abstract
In this paper, environmental impact of polyethylene tubes of different volumes: 30 mL and 100 mL was assessed using the life cycle assessment. The data were collected on the types and amounts of the materials and energy consumption in the process of packaging and distribution and inserted in the software GaBi 5. Total mass life cycle inventory was considerably lower for the smaller volume packaging. Breaking the inventory to the single flows, it was found that in both life cycles (polyethylene tubes of 30 mL and 100 mL) the highest contribution had the flows of fresh water consumption, emission of inorganic elements to the air and fresh water pollution with waste water flows. The highest contribution to all of these flows was shown to be production and consumption of diesel fuel. The results of this paper show that in analised case, more environmental friendly is the larger volume packaging.
