초록
우리나라는 제조업 중심 국가로서 다양한 분야에 많은 양의 금속이 사용되나, 이들 금속이 대부분 수입에 의존하고 있다. 상당수의 금속은 전세계적으로 제한된 부존량 및 생산량에 비해 소비량이 증가하는 실정이다. 어떤 금속들은 부존 및 생산국가가 편재되어 있는 경우가 종종 있어 향후 공급의 불안정성이 우려된다. 또한 이러한 금속이 유해성을 띄고 있을 경우 환경적 측면에서도 문제가 된다. 이를 해결하기 위해 사업장 폐기물내 유해성 유가금속 회수 및 재활용을 통해 공급을 안정화시키고 환경오염을 예방할 수 있으나, 유가 금속의 종류 및 국내 배출업체와 배출폐기물 종류가 매우 많아 초기에 관련 현황파악이 번거롭다. 따라서, 본 연구에서는 공공기관 공개자료를 통해 향후 국내산업에 중요한 유해성 유가금속 선정결과를 소개하고, 국내 화학물질 배출 ․ 이동량 정보 등을 이용하여 이러한 금속(니켈, 코발트, 망간 등)를 함유 폐기물을 배출하는 업체들을 보다 용이하게 초기 현황파악 하는 방안을 순서도 형식으로 제시하였다.
Abstract
Korea, one of the manufacturing-oriented countries, consumes a large amount of metals in various industrial areas, but should depend on import of most of the metals from foreign countries. Also, global metal consumption amounts are increasing in relation to those of the world's reserve and production. Some metals are limitedly produced from only several centuries, which might lead to instability of the future supply of those metals. In addition, when such metals are hazardous, those may result in various environmental troubles with contamination. To resolve those issues, the recovery and the recycling of hazardous but valuable metals in industrial waste are desirable. However, there are overwhelming numbers of the metal types, waste generators, and amounts of wastes containing the metals, so it can be troublesome even to implement a preliminary status analysis to screen proper metals, wastes with the metals, and waste producers. Therefore, this study introduces the valuable metals for Korean industry, announced by public institutions, Also, a flow chart is suggested to facilitate a preliminary status analysis, using the domestic PRTR (Pollutant Release and Transfer Register) database, to screen proper waste producers containing some of hazardous but valuable metals such as nickel, cobalt, and manganese.
