초록

본 연구에서는 유리병 재사용에 대한 환경영향을 알아보기 위하여 전과정평가를 수행하였다. 연구범위로는 제품제조 및 원료수송 단계로 한정지었으며 360 mL 유리병 한 개를 기능단위로 사용하였다. 고려된 환경영향 범주는 6개로 자원고갈, 산성화, 부영양화, 지구온난화, 오존층파괴 및 광화학산화물 생성 등이었다. 전과정평과 결과, 자원고갈이 48.63%, 지구온난화가 46.27%로 두 범주가 가장 큰 환경영향을 보였으며 나머지 범주들은 상대적으로 미미한 영향을 보였다. 전체 공정 중 신병제조공정에 사용되는 화학약품에 의한 환경영향이 71.24%로서 주요인으로 나타났고 전력사용은 16.74%, 수송은 11.8%로 다음을 차지하고 있다. 또한 신병제조공정에 투입되는 화학약품 중 규산나트륨에 의한 환경영향이 45.68%를 차지하고 있어 자원고갈 및 지구온난화에 대한 기여도가 가장 큰 것으로 보인다.

Life Cycle Assessment (LCA) has been studied on the reuse of glass bottles. The system boundary in this study encompassed from gate to gate such as production and transportation. A 360 mL volume of a glass bottle was selected as the functional unit. The environmental impact assessments was studied on 6 categories including abiotic resource depletion, acidification, eutrophication, global warming, ozone depletion, and photochemical oxidant creation. The results showed that the most significant impact categories were abiotic resource depletion (48.63%) and global warming (46.27%), and the rest categories revealed insignificant impacts. In the whole system, the chemicals used for the new bottle production revealed the major contribution to the environmental impacts (71.24%), followed by the use of electricity (16.74%) and transportation (11.8%). In addition, the environmental impact of sodium silicate to be put into the stage of the new bottle production was found to be 45.68%, causing severe influence on abiotic resource depletion and global warming.
