Abstract

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.

본 연구는 탄소중립 이행에 따른 핵심 광물 공급망 리스크와 글로벌 규제에 선제적으로 대응하기 위해, 희소금속 재자원화 공정 및 강원권 중심의 거점 구축 전략을 고찰하였다. 청정에너지 제품군의 내재량 분석 결과, 하이브리드 제련 공정은 1차 생산 대비 온실가스 배출량을 60~95% 감축하는 것으로 확인되었다. 공학적·경제적 병목현상 극복 방안과 함께, 강원도의 산업 특성을 반영한 3대 권역(서부, 동해안, 남부) 특화 클러스터 모델을 제안하였다. 본 연구는 ｢국가자원안보 특별법｣과 연계하여 강원권을 국내 자원순환의 핵심 거점으로 육성하는 학술적·정책적 가이드라인을 제공한다.
