The objective of this study is to assess the environmental effect of the reclaimed land drainage method using oyster shell through the Life cycle CO2assessment, and to evaluate the applicability in South Korea. In this Study, the life cycle CO2 emissions of oyster shell (OS) and crushed stone (CS,as avoided product) were assessed and compared. The Life Cycle Assessment method was used for quantitative evaluation of direct or indirectenvironmental effects of OS recycling. CO2 was selected as the evaluation target material, and the scope of assessment includes the acquisition ofmaterials, processing, transportation, construction phases. Compared to using CS, 77.0% of CO2 emissions in acquisition and processing, 47.0% intransportation and 6.5% in construction phase were reduced, respectively by using of OS. The maximum transportation distance of OS was estimatedaccording to transportation distance of CS. OS has environmental advantages than CS within about 26 - 101 km from the source. OS was found tobe applicable to reclaimed lands up to 810 ha, 3,910 ha from Tongyeong and Yeosu, respectively. In addition, the amount of OS that could be usedas drainage material for reclaimed land was much higher than annual OS production of South Korea. Therefore, it is considered that OS is sufficientto be used as drainage material for reclaimed land in South Korea.
