Abstract

This study was performed to investigate the contents and leaching characteristics of hazardous wastes from the paint industry. In order to establish a hazardous waste list, samples from industrial discharge have been analyzed for 8 non-regulated inorganic hazardous substances (i.e., Sb, Ni, F, V, Ba, Zn, Be, Se). In more detail, hazardous waste samples from a total of 64 workplaces, e.g. manufacture, formulation, supply and use (MFSU) of coatings, adhesives, sealants and printing inks processing, have been chosen and analyzed. Contents and leaching tests for inorganic metal species in samples show that the non-regulated hazardous substances satisfy all the criteria, while quantitative analyses reveal that some samples of the discharged wastes exceeded the criteria proposed by NIER (National Instituted of Environmental Research). In conclusion, we expect the outcome of this study to align the classification system of hazardous waste management in South Korea with international legislations, and consequently contribute to reduce environmental pollution as well as health risks by toxic wastes.

본 연구에서는 국내 유해폐기물의 효율적인 관리를 위해 도료공정에서 발생한 폐기물 중 미규제 중금속의 배출특성을 조사하였다. 사업장은 올바로시스템에 등록된 폐기물 배출업체를 대상으로, 유럽의 도료공정(European Waste Catalogue, EWC 08)과 유사한 폐기물 발생 업체로 하였으며 조사대상 사업장 64개 업체를 현지 방문하여 원료, 생산제품, 생산 공정, 폐기물의 종류 및 배출과정을 조사하고 생산 공정에서 배출되는 73개의 폐기물을 채취하였다. 모든 시료에 대하여 함량 분석을 수행하였고, 특히 고상시료 16건에 대해서는 중금속 8항목(Ba, Be, F, Ni, Sb, Se, V, Zn)에 대한 용출분석을 수행하였다. 도료공정에서 발생된 폐기물 중 ICP-MS를 이용한 Ba의 함량분석 결과는 ND (Not Detected)~44,973.00 mg/kg의 농도 범위를 나타내었다. 특히 폐페인트 시료 7건, 폐수처리오니 2건, 공정오니 1건 및 폐유기용제 1건에서 Ba이 제안기준인 500 mg/kg을 초과하였으며 나머지 미규제 항목은 검출되지 않았다.
