초록

재제조는 사용 후 제품을 분해, 세척, 검사, 보수, 조정, 재조립하여 원래의 성능 또는 그 이상의 성능을 가진 제품으로 재상품화하는 것으로, 재제조산업은 2050 탄소중립을 실현하기 위해 필요한 핵심 산업이다. 본 연구에서는 자동차부품 중 재제조가 활발히 이루어지고 있는 인젝터를 대상으로 전과정평가를 이용하여 회피효과를 고려 시와 미고려 시 자원 저감 및 온실가스 저감 효과를 분석하고자 한다. 연구결과, 인젝터 재제조로 인한 자원 저감 효과와 온실가스 저감 효과는 회피효과를 미고려 시 1개 기준으로 95.30%, 93.88%가 저감되는 것으로 나타났다. 재제조 시 제품을 재사용함으로써 사용 후 제품이 폐기되지 않는 환경영향과 천연자원을 사용하지 않는 환경영향의 회피효과를 고려할 시 190.91%, 188.33%가 저감되는 것으로 나타났다. 본 연구결과는 향후 재제조 시 회피효과를 고려한 환경영향 저감량을 평가하고, 연구방법론 개발 시 활용할 수 있을 것으로 본다.

Remanufacturing re-commercializes a used product to achieve an equal or higher performance level than the original product by disassembling, cleaning, inspecting, repairing, reconditioning, and reassembling the used product. The remanufacturing industry is a key industry necessary to realize carbon neutrality by 2050. This study uses life cycle assessment to analyze the resource reduction and greenhouse gas reduction effects with and without considering the avoided effect for an injector, which is an automobile part that is actively being remanufactured. The results of this study showed that the resource reduction effect and greenhouse gas reduction effect induced by injector remanufacturing were reduced by 95.30% and 93.88%, respectively, based on one unit without considering the avoided effect. However, when considering the avoided effect, which in this case is the environmental impact of not disposing of the used injector and not having to use natural resources to manufacture a new injector because the used injector was reused during remanufacturing, the resource reduction effect and greenhouse gas reduction effect were 190.91% and 188.33%, respectively. The results of this study are expected to be used in the future to evaluate the amount of environmental impact reduction while considering the avoided effect during remanufacturing and to help develop research methodology for remanufacturing.
