Abstract

Korea has an economy based on manufacturing industrial fields, which produce high amounts of hazardous wastes, in spite of few landfill candidates, and a significant concern for fine airborne particulates; therefore, traditional waste management is difficult to apply in this country. Moreover, waste collection and accumulation have recently been intensified by the waste import prohibitions or regulations in developing nations, the universalization of delivery services in Korea, and the global COVID-19 crisis. This study thus presents a domestic waste management strategy that aims to address the recent issues on waste. The contents of the strategy as the main results of the study include the (1) improvement of the compatibility of the classification codes between the domestic hazardous waste and the international ones such as those of the Basel Convention; (2) consideration of the mixed hazard indices to represent toxicity from low-content components such as rare earth metals often contained in electrical and electronic equipment waste; (3) management application based on risks throughout the life cycles of waste; (4) establishment of detailed material flow information of waste by integrating the Albaro system, Pollutant Release and Transfer Register (PRTR) system, and online trade databases; (5) real-time monitoring and prediction of the waste movement or discharge using positional sensors and geographic information systems, among others; and (6) selection and implementation of optimal treatment or recycling practices through Life Cycle Assessment (LCA) and clean technologies.

우리나라는 제조업 중심의 경제구조상 각종 유해폐기물이 발생하고 있으나 매립후보지가 적고 소각처리의 경우 미세먼지의 발생에 대한 우려가 커서 전통적인 폐기물 처리가 쉽지 않다. 더구나 최근에는 개발도상국의 유해폐기물 수입규제, 배달문화의 보편화와 보건위기사태까지 겹쳐 폐기물 수거 및 적체 문제가 심화되고 있다. 본 연구에서는 특히 최근 폐기물 국제 규제 관련 추세에 맞춘 국내 폐기물 정보관리 전략을 제시하려 하였다. 그 내용은 (1) 국내 유해폐기물 분류 코드와 바젤협약 등 국제적 코드와의 정합성을 제고하려는 노력을 지속해야 하며 (2) 폐전자제품내 희토류 등 저함량 성분의 혼합 유해성을 고려해야 하고 (3) 유해폐기물 전주기 위해성을 기반으로 하는 관리가 수행되어야 한다. 또한 (4) 올바로시스템, 화학물질배출·이동량 정보공개시스템 및 폐기물 수출입 자료 등을 서로 연동하여 폐기물 상세 흐름 정보를 구축하고 (5) 센서와 지리정보 시스템 등을 활용하여 폐기물 흐름의 감시와 불법오염지역의 예측이 필요하다. 마지막으로 (6) 청정기술과 전과정평가 등으로 처리/재활용의 최적대안을 선정/수행하는 것이 바람직하다.
