레디믹스트 콘크리트의 환경성적표지 현황 및 특성 분석 = Analysis of the Present Status and Characteristics of Environmental Product Declaration of Ready-mixed Concrete

다국어 초록 (Multilingual Abstract)

Recently, in the concrete industry, the development and commercialization of low-carbon products ofready-mixed concrete have emerged as part of the efforts to realize carbon neutrality. This study aimsto investigate the current status of environmental product declaration(EPD) of ready-mixed concreteand to analyze the characteristics of carbon emissions by compressive strength, life cycle stage, andregion. To this end, the related certification system requiring the calculation of carbon emissions in theconcrete industry was analyzed. The target of analyzing the current status of carbon emissions was setas a product of ready-mixed concrete that acquired EPD certification based on the life cycle assessmentmethod. In addition, the trend of carbon emissions according to each characteristic was reviewed byanalyzing carbon emissions by the life cycle of ready-mixed concrete products, analyzing carbonemissions by standard, and analyzing carbon emissions by region. As a result, the carbon emissions inthe pre-production stage were 99% compared to total carbon emissions., and as it increased from18MPa to 40MPa, carbon emissions also increased. Even with the same specifications, the carbonemissions in the capital region were higher than in the southern region.

본 연구는 레디믹스트 콘크리트의 환경성적표지 현황 조사와 이를 통한 레디믹스트 콘크리트 규격, 생애주기, 권역별 탄소배출량 특성 분석을 목적으로 한다. 이를 위해 콘크리트 산업의 탄소배출량 산정이 요구되고 있는 관련 인증제도를 분석하고, 레디믹스트 콘크리트 제품의 탄소배출량 현황분석을 위해 전과정평가 기법에 기반한 EPD 인증을 받은 제품군을 대상으로 하여 레디믹스트 콘크리트의 활성화 정도를 분석하였다. 또한 레디믹스트 콘크리트 제품의 생애주기별 탄소배출량분석, 규격별 탄소배출량 분석, 권역별 탄소배출량 분석을 수행하여 각 특성에 따른 탄소배출량 추이를 검토하였다. 분석결과 생애주기별 탄소배출량은 제조전단계가 99% 수준을 나타냈으며, 18MPa에서 40MPa로 증가할수록 탄소배출량도 증가하는 추세를 보였다. 단, 동일 규격이라고 하더라도 수도권의 탄소배출량이 남부지역 대비 높은 탄소배출량을 나타냈다.
