초록

Aluminum can is one of the common and economically valuable recycling items in municipal waste streams. In thisstudy, the reduction rate of the greenhouse gas emission and energy savings were estimated when aluminum cans arerecycled by using material flow analysis, US EPA WARM method, and EU Prognos method. Based on the results,approximately 16,630 ton of aluminum in 2010 was recovered as ingot, while 10,873 ton of aluminum can to can recyclingoccurred in the same year. The reduction rate of aluminum recycling was estimated to be 240,986 tCO2eq/yr by US EPAWARM method, while about 305,283 tCO2eq/yr was found by the recycling using EU Prognos method. The differenceresulted partly from the different system boundary and the loss rate during aluminum recycling process. The results ofthe energy savings and greenhouse gas reduction rate would be valuable for waste management policy makers to estimatethe potential reduction rate of greenhouse gas by aluminum can recycling and accelerate recycling infrastructure of wastestreams. This study also implies that the applications and results of both methods to estimate greenhouse gas reductionrates by aluminum can recycling should be carefully reviewed and acknowledged before the use of the method due tothe different assumptions and results that are anticipated.
