Abstract
Iindium-tin-oxide (ITO) material was had to use in display application as transparent electrode. However it would be problems comes up, the depletion of indium, tin and energy consumption of production process. Therefore recently trend was demanded alternative ITO material and recycling/reused ITO. In this conditions, the environmental impact have to express correct value about recycling/reused ITO process. The life cycle assessment was valuable method in this process. Thus first step was carried out separating in/out put (material) sources and then, exactive data base (DB) was applied. The result of environment impact was calculated by affect categories and recycling rate was set to 34% (This value was measured in previous project). The rate (g) of ITO material was calculated by chemical equivalent. In result, environmental impact were revealed acidification potential and abiotic depletion and if do not recycle/reuse ITO, $ 476 per 1 ton waste in land.
