요약문

본 연구는 전과정평가 기법을 사용하여 전기전자 및 자동차 제품군을 위한 기초소재로 사용되는 8개의 철강제품에 대한 전과정목록 데이터베이스를 개발하고 철강제품들에 대한 환경부하 및 환경영향을 비교분석하였다. 먼저 환경부하에 관하여 철강제품의 전과정을 통하여 배출되는 온실가스의 직간접 배출량을 비교하였다. 또한 철강제품에 대한 전과정목록분석의 결과로부터 유도된 자원고갈과 지구온난화, 산성화에 대한 환경영향을 평가하였다.

Abstract

This study is intended to develop the life cycle inventory (LCI) database on 8 steel products which are basic materials for the electric and electronic appliances and automobiles using life cycle assessment (LCA) methodology, and to compare the environmental loads and environmental impacts between them. For the environmental loads the direct and/or indirect amounts of GHG emission throughout those life cycle are compared. And the environmental impacts such as abiotic resource depletion, global warming and acidification induced from life cycle inventory analysis (LCI) results on the steel products are evaluated.
