Environmental aspects associated with the life cycle of beverage can have been studied, using the method of life cycle assessment(LCA) which has become one of the most powerful tool in assessing the environmental impacts. A life cycle inventory table is obtained by indentifying and quantifying all the inputs and outputs related to the beverage can throughout its life cycle, i.e. from raw material acquisition to waste disposal. As the results of life cycle inventory analysis(LCI), it is found out that the largest amount of general airborne emission is CO₂which is responsible for 44.7% of the total airborne emissions. With respect to water-borne emissions, the contributions of Cl₂, suspended solids(SS), COD, and waste lubricants are significant. Also, 3.13kg of scrap as solid wastes is produced for 1,000 pieces of 250ml can Life cycle impact assessment(LCIA) shows that the global warming effect is the most dominant environmental effect which can be caused by the beverage can system. The use of electric energy in the manufacturing stage of the can is the biggest source for CO₂emission which is the main reason for the global warming.
