탄소중립을 위한 희소금속 재자원화 기술 동향과 강원권 순환경제 거점 구축 전략

초록

This study examines trends in recycling technology for rare metals and proposes strategies for a circular economy hub in Gangwon State to mitigate global supply chain monopolies and trade barriers. An analysis of critical minerals embedded in clean energy technologies confirms that hybrid metallurgical processes reduce greenhouse gas emissions by 60–95% compared to primary production. The research addresses current economic and engineering bottlenecks by optimizing life-cycle costs (LCC). A strategic three-zone cluster model, incorporating pre-treatment, hybrid smelting, and resource recovery, is proposed to leverage the regional characteristics of Gangwon State. This paper provides a comprehensive blueprint for developing the region into a national testbed for carbon- neutral recycling of rare metals in alignment with the Special Act on National Resource Security.
