초록

본 연구에서는 비촉매분야에서 사용된 로듐의 재자원화 시, 경제적 및 환경적 효과를 분석하였다. 분석방법으로, 경제적 효과 분석은 비용편익분석과 자원절감효과분석을 적용하였으며, 환경적 효과 분석은 전과정평가를 적용하였다. 연구결과, 경제적 측면에서 B/C 값은 1.28로 사업성이 있는 것으로 나타났으며, 비용절감은 재자원화 로듐 1 g 기준으로 237,000원로 나타나 2025년 로듐 재자원화량 71.7억원으로 나타났다. 환경적 효과는 로듐 1 kg 기준의 재자원화 시와 해외매각 시에 대해 온실가스 배출량을 비교하였다. 산정 결과, 로듐 1 kg 기준으로 재자원화 시 온실가스 배출량은 65 kg CO2eq./kg-Rh, 해외매각 시 28,800 kg CO2eq.으로 나타나, 99.8%가 저감되었다. 본 연구결과는 비촉매분야에서 사용되는 로듐의 재자원화 시 경제적 및 환경적 효과 분석을 통해 자원이 부족한 우리나라에서 로듐 재자원화가 필요하다는 것을 제시할 수 있었다.

This study analyzed the economic and environmental effect of recycling rhodium used in the non-catalytic field. As an analysis methodology, economic effect analysis applied cost-benefit analysis and resource-saving effect analysis and the environmental effect analysis applied life cycle assessment (LCA). The results show that from an economic point of view, the cost-benefit ratio was 1.28, which was feasible, and the cost reduction was 237,000 won based on 1 g of rhodium recycled and the amount of rhodium recycled was 7.17 billion won in 2025. As for the environmental effect, the greenhouse gas(GHG) emissions were compared between the case of recycling based on rhodium 1 kg and the case of overseas sales. The calculation results show that based on rhodium 1 kg, greenhouse gas emissions were reduced by 99.8%, from 65 kg CO2eq./kg-Rh when recycling to 28,800 kg CO2eq. when sold overseas. The results obtained from this study could suggest that rhodium recycling is necessary in Korea where resources are scarce by analyzing the economic and environmental effect of recycling rhodium used in the non-catalytic field.
