초록

최근 전자산업의 급격한 성장으로 전자부품스크랩의 발생량 역시 빠르게 증가하고 있다. 특히 전자부품스크랩의 구성부품 중 인쇄회로기판(PCB)은 금, 은, 구리, 주석 및 니켈 등 일반금속부터 귀금속 및 희소금속까지 포함하고 있는 중요한 재활용 대상이다. 하지만 국내에는 일부 대기업을 중심으로 한 PCB 처리 및 재활용 기술이 상용화되어 있으며 그 외 처리량에 대해서는 정확하게 집계되지 않고 있는 실정이다. 이에 따라 몇몇 도시광산 업체 및 연구소, 대학교를 중심으로 기존 대기업 중심의 상용화 공정 외에 PCB로부터 유가금속을 회수하고 원료로 재사용하는 연구가 진행되고 있다. 따라서 본 연구에서는 국내의 폐 PCB의 처리 및 회수현황과 재활용 기술 동향을 분석하였고, 이를 통해 PCB 폐자원의 자원순환 활성화에 기여하고자 하였다.

Recently, the amount of electronic scrap is rapidly increasing due to the rapid growth of the electronics industry. Among the components of electronic scrap, the printed circuit board(PCB) is an important recycling target which includes common metals, precious metals, and rare metals such as gold, silver, copper, tin, nickel and so on. In Korea, however, PCB recycling technologies are mainly commercialized by some major companies, and other process quantities are not accurately counted. According to present situation, several urban mining companies, research institutes, and universities are conducting research on recovery of valuable metals from PCBs and/or reusing them as raw materials that is different from existing commercialization process developed by major companies. In this study, we analyzed not only current status of collection/disposal process and recycling of waste PCBs in Korea but also the trend of recycling technologies in order to help resource circulation from waste PCBs become more active.
