요약문

본 연구는 전과정평가(LCA)를 활용하여 친환경적인 폐차처리시스템의 환경영향을 평가하는데 그 목적이 있다. 본 연구 는 보다 자세한 환경적 주요이슈 규명을 위하여 gate to gate와 gate to grave 관점에서 LCI, LCIA 연구를 수행하였으며, 연구 결과에 대한 이해를 용이하게 하기 위하여 부분적으로 기존 폐차처리시스템의 결과를 비교하는 형태를 취하였다. LCI 연구 결과 전기의 사용과 CO2, coal, NOx, iron 등이 주요이슈로 규명되었으며, LCIA의 연구를 통해서 환경영향에 큰 기여를 하고 있는 공정으로는 고철재활용공정, 압축차체파쇄공정, 폐엔진해체공정 등이 있는 것으로 드러났다. 또한 재활용 가능율이 85%인 경우의 환경영향을 규명한 시나리오 분석에서 기존 폐차처리시스템에 비해 친환경적 폐차처리시스템의 환 경성이 우수한 것으로 분석되었지만 환경영향을 더 감소시킬 수 있는 개선의 여지가 남아 있는 것으로 나타났다.

Abstract

This study aims at evaluating the environmental impacts stemmed from an environmentally friendly treatment system for ELVs, using Life Cycle Assessment(LCA) methodology. In this study, both LCI and LCIA study were conducted with a perspective of gate to gate as well as gate to grave in order to figure out more detailed environmentally significant issues. For the purpose of making this study easier to be understood, the comparative approach with existing ELV treatment system were partly applied in this study. As one of the results from LCI study, use of electricity and environmental parameters such as CO2, coal, NOx and iron were found out to be the significant issue parameters. From the LCI and LCIA study, it was shown that the significant environmental aspects were related with the recycling process of ferro scrap, the shredding process of compressed car bodies and the dismantling process of end-of-life engines. In addition, a scenario analysis dealing with change of the environmental performance in case of 85% reuse & recycling rates was conducted. Based on these results, it was revealed that this environmentally friendly treatment system for ELVs have generally better environmental performance than existing ELV treatment system but still have some areas to cut down on environmental impact further.
