Abstract

사용 후 제품을 회수하여 완전 해체하고 부품들을 세척, 수리, 또는 새로운 부품으로 교체하여 재조립함으로써 신품과 동일한 성능 수준으로 재 제품화 하는 재제조는 천연자원과 에너지 사용의 저감 등 자원순환 측면에서의 환경적 개선효과가 뛰어나 자원 측면에서 주목받고 있다. 재제조는 뛰어난 환경개선 효과 및 자원보존으로 인해 우리나라에서 많은 연구가 수행되어왔으며, 현재 자동차 부품, 프린터 토너 및 카트리지를 중심으로 재제조가 이루어지고 있다. 하지만 코어의 상태가 양호한 상태로 반환되어 재제조 공정을 거쳐 새 제품과 동일한 상태의 재제조품 생산이 가능한 렌탈 제품은 아직까지 활성화 되어있지 않다. 따라서, 본 연구에서는 LCA 기법을 이용해 렌탈 제품 중 하나인 공기청정기 신품과 재제조 제품의 환경성평가를 수행하였으며, 이를 통해 렌탈 제품 신품 대비 재제조품의 환경적 개선 효과를 정량적으로 분석하였다. 분석결과 공기청정기 1대 재제조 시 환경영향은 신품대비 약 20.7% 감소하는 것으로 나타났다. 환경과 관련된 영향범주 중 오존층 파괴(ODP)가 94% 감소하여 가장 큰 효과가 있는 것으로 나타났으며, 공기청정기의 수명주기에서 원료 추출 단계에서는 자원고갈(ADP) 및 지구온난화(GWP)에 대한 환경개선 효과가 가장 큰 것으로 나타났다.

Remanufacturing that is the rebuilding of a product to specifications of the original manufactured product by collecting used-product, completely disassembling, cleaning and repairing or replacing with a new part and reassembling has been received attention in aspects of resource, recycling because it is a great environmental improvement. Remanufacturing is the rebuilding of a product to specifications of the original manufactured product by collecting used-product, completely disassembling, cleaning and repairing or replacing with a new part and reassembling. With a great environmental improvement and resource recycling and conservation, many studies were conducted. Up to date, remanufacturing activities are mainly applied to automobile parts and printer toner cartridge in South Korea. However, remanufacturing of rental product is not well conducted although rental products are collected in good condition and could be remanufactured in the same condition as a new product. Therefore, in this study, we conducted life cycle assessment (LCA) to an air cleaner product that is one of rental products. This study attempts to identify the processes in new products and remanufacturing life cycles that contribute the most environmental impacts. The results show that air cleaner remanufacturing could reduce about 20% of environmental impacts compared to new product. The greatest benefit related to environmental impact is with regard to ozone layer depletion potential (ODP), which is reduced by 94%. In the life cycle of air cleaner, raw material extraction stage had the most environmental impacts, especially with regard to abiotic depletion potential (ADP) and global warming potential (GWP). In the environmental impacts in each part, the ABS power had the highest environmental impacts.
