초록

LED 산업은 기술의 발전과 에너지 절감 정책을 바탕으로 수요가 급증하면서 시장은 급격히 확대되고 있다. 그에 따라 지속적으로 축적되는 LED 폐자원의 효율적인 재활용이 사회적 관심으로 증가하고 있어 현재 LED 폐자원의 재활용 상황과 향후 나아갈 방향에 대해고찰하였다. 현재 LED 폐자원의 재활용은 Ga 회수기술에 초점이 맞춰져 있어 전처리 및 고부가가치 소재의 농축/회수 등 통합적인 재활용 기술 개발이 요구되는 상황이다. 본 논문에서는 LED 폐자원의 현황 및 재활용 기술을 알아보고 향후 방향에 대해 제시하였다.

Abstract

Owing to technological advancements and energy-saving policies, the demand for LED is increasing, leading to rapid industry expansion. Consequently, efficient recycling of accumulated LED waste has become a growing social concern, and current recycling status of LED waste resources and future directions were reviewed. Currently, waste LED recycling is focused on Ga recovery. Therefore, the development of integrated recycling technologies such as pre-treatment and concentration/ recovery of high valued materials is necessary. In this study, we investigated the status and recycling technologies of waste LED and presented prospects.
