요약문

국내에서 생산되는 전기로 제강 제품군에 대해 원료채취부터 제품생산까지에 대한 전과정평가를 수행하였다. 대상제품군 은 형강, 봉강, 철근, 레일이다. 각 대상제품군별 국내생산량이 가장 큰 업체 2-3곳을 선정하여 전과정목록 데이터베이스를 구축하였다. 또한 전과정목록 분석결과를 토대로 대상제품군별 환경영향평가지수를 산출하였다. 환경영향평가지수는 형강, 봉강, 철근, 레일이 각각 5.05E-05, 1.22E-04,5.36E-04, 4.25E-05으로 봉강의 환경영향이 형강에 비해 약 2.4배가량 높다. 대체적으로 지구온난화 범주에 미치는 환경영향이 매우 큰 것으로 조사되었으며, 원인을 찾기 위해 제품 생산 단계를 세분하 여 CO2 분석을 수행하였다.

Abstract

Life Cycle Assessment has been conducted from raw material acquisition to manufacturing for Electric Arc Furnace Steel products manufactured in Korea. The product category under investigation included steel sections, round bars, deformed bars and rails. Two or three major manufacturing companies were chosen for each product category in establishing life cycle inventory database. Eco-indicator for each product category was calculated based on the life cycle analysis results. The eco-indicators of steel sections, round bars, deformed bars and rails were 5.05E-05, 1.22E-04, 5,36E-04 and 4.25E-05 respectively - environmental impact caused by round bars is approximately 2.4 times grater than by steel sections. The main impact category for the most products is global worming in accordance with the result of LCA. Therefore, CO2 analysis was conducted to identify the most contributing activity to global worming category.
