LG생활건강에서 생산되는 액체 주방세제의 환경성을 조사하기 위하여 전과정평가를 실시하였다. 제품별 전과정목록표를 도출하였으며, 이를 이용하여 수생태독성, 지구온난화, 광화학스모그, 인간독성, 산성화, 부영양화에 대한 영향평가를 수행 하였다. 그 결과, 제품 전과정 가운데 제품 폐기단계에서 환경영향이 가장 높게 나타났고, 특히 수생태독성에 의한 영향이 높게 나타났다. 주방세제의 환경지수에 영향을 미치는 원인물질을 찾아내고 개선물질로 대체하여 환경지수가 18% 감소한 제품을 개발하였다.
Abstract
With the kitchen detergents produced by LG Household & Healthcare, we performed life cycle assessment to examine their environmental properties. Life cycle inventories of kitchen detergent were drawn, and the impact assessment on six categories including aquatic ecotoxicity, global warming, photochemical oxidant formation, human toxicity, acidification, and eutrophication was made using the inventories. As a result, it was found that environmental load is the highest at the end of life, and the worst impact category is aquatic ecotoxicity. We found the major ingredient determining environmental indicator and replaced it with more environmentally friendly material, so that the product of 18%-improved environmental indicator was developed.
