Abstract
A Life Cycle Assessment (LCA) study was carried out to identify and improve the environmental aspects associated with the present incineration system of spent Li-ion batteries (LIBs) in Korea. The environmental impact associated with the landfill of the incineration ash was also assessed in this study, while so far it was excluded in most studies. It was found out that the $CO_{2}$ emission from the electricity generation as well as the incineration process and heavy metals emissions to air and water accounted for about 90% of total environmental impacts. In particular, the effect of the emission of heavy metals were dominant. In oder to improve the current incineration system environmentally, it is needed to incinerate the wastes like spent LIBs which contained relatively high portion of heavy metals separately from other combustible wastes. On the other hand, the effect of the landfill of ash after incineration was insignificant since the ash from the incineration process was chemically stable.
