초록

급성장하고 있는 태블릿 PC와 스마트 폰과 같은 모바일 기기들은 제품 표면 보호를 위해 강한 소재인 터치스크린패널을 장착하고 있다. 따라서, 화학강화유리의 수요는 증가하게 되었고, 수요가 증가함에 따라 화학강화유리의 폐기량도 증가하게 되었다. 이 연구의 목적은 물질전과정평가(material life cycle assessment, MLCA) 기법을 사용하여 터치스크린패널에 사용되는 화학강화유리의 환경영향평가를 하는 것이다. MLCA의 소프트웨어로는 그란타의 씨이에스(CES), 시마프로(SimaPro), 가비(Gabi)를 사용하였다. 씨이에스 소프트웨어(CES software)를 통하여 2.7, 5.7, 10.3 inch 두께의 화학강화유리의 환경영향 평가를 2가지 경우(폐기, 재사용)를 고려하여 수행하였다. 그 결과, 2.7, 5.7, 10.3 inch 화학강화유리를 재사용할 경우에 사용되는 에너지 값과 CO2값은 폐기할 경우에 비해 약 51.4%, 46.6% 감소하는 것을 확인하였다. 시마프로 소프트웨어(SimaPro software)를 통해서는 11가지 영향범주를 평가하였는데, 11가지 영향범주 중에서 화석연료(fossil fuels), 무기물(inorganics)과 기후변화(climate change)가 주된 환경부하의 원인으로 나타났다. 그리고 가비(Gabi) 소프트웨어를 통해서 환경영향의 주된 원인이 안티몬(antimony), 불화수소(hydrogen fluoride)라는 것을 알 수 있었다.

Rapidly growing mobile machines such as tablet PC and smart phone are equipped with touch screen panel using a sturdy material for products surface protection. Therefore, surge of chemically strengthened glass was increased and the amount of waste matter is proportional to demand. The purpose of this study is environmental impact assessment on touch screen panel of chemically strengthened glass by material life cycle assessment (MLCA). We used CES of Granta, SimaPro and Gabi software for MLCA. Chemically strengthened glass (2.7, 5.7 and 10.3 inch) was calculated to environmental impact assessment by Granta software under two cases. One case is Landfill and the other case is Reuse. As a result, in case of reuse, energy values of 2.7, 5.7 and 10.3 inches were reduced by an average of 51.4%, CO2 values were reduced by an average of 46.6% than Landfill case, respectively. We assessed impact categories of 11 types using SimaPro software. As a result, the contents of fossil fuels, inorganics and climate change have a huge impact than the other impact categories. And the main cause of environmental impact is antimony and hydrogen fluoride in Gabi results.
