Abstract

Car exhaust $CO_2$ gas reduction and fuel efficiency of the car lighter for the current era is a big challenge. The developments of high-performance Nd magnets, Li-ion secondary battery and exhaust gas purification performance of PGM catalysts used in the lightweight EV and HEV are activated. Country in order to improve the car lighter and function that use the resources of rare metals are ubiquitous imported from China because of export supply control, as soaring prices have unstable supply and demand. Compared to the emissions from the next-generation automotive recycling, waste scarce resources need to be. This study investigated the recycling technology analysis and development of the information technology, or delivered to the researchers by giving national car industry aims to contribute to the development. Findings, pulmonary high-performance motor vehicle emissions in the exhaust gas purification PGM Catalysts, Li-ion battery and Nd magnets recycling technology, such as pre- and post-processing techniques to classify technology, pre-urban mining technology mechanical separation by screening techniques under development, the study and post-processing technology has, pyro and hydro metallurgical smelting technology is established. Waste Recycling in terms of economic efficiency of mechanical components for the intensive study of screening techniques is needed.

탄산가스 삭감과 자동차 연비를 향상시키기 위한 자동차의 경량화는 현시대적 큰 과제이다. 경량화를 위하여 Hybrid Electrical Vehicle(HEV), Electrical Vehicle(EV)의 고성능 모터용 Nd 자석, Li이온 2차전지 및 배기가스 정화용 PGM촉매의 성능개발이 활성화 되고 있다. 우리나라는 자동차 경량화와 기능 향상을 위하여 사용하는 희소금속을 자원이 편재되어 있는 중국 등에서 수입하기 때문에 수출국의 공급 조절, 가격 폭등 등으로 수급이 불안정한 경우가 있다. 이를 대비하여 차세대 자동차에서 배출되는 폐 희소자원을 리싸이클링 할 필요가 있다. 본고는 리싸이클링 기술과 현상에 대하여 조사 분석한 정보를 기술자나 연구자에게 전해주어 국가 자동차 산업 발전에 기여하는데 목적이 있다. 조사 결과, 폐 자동차에서 배출되는 고성능 모터, 배기가스 정화용 백금족금속(PGM) 폐촉매, Li이온 배터리 등의 리싸이클링기술은 전처리 기술과 후처리 기술로 분류하는데, 전처리 기술인 기계적 분리 선별 기술은 연구 개발 중이며, 후처리기술인 습, 건식 제련 기술은 확립되어 있다. 리싸이클링 경제성 측면에서 폐 부품의 기계적 선별 기술에 대하여 집중적으로 연구할 필요가 있다.
