Abstract

Although Korea is a top market sharing and world leading producer and developer of flat panel display devices, relevant recycling technology is not up to her prestigious status. Besides, most of the waste glass arising from flat panel displays is currently land-filled. The present paper mainly reviews on development of recycling systems for waste TFT-LCD glass from end-of-life LCD TVs and monitors and TFT-LCD process waste of crushed glass particles with target end uses of raw material for high strength concrete pile and glass fibers, respectively. Waste LCD glass was recycled to fabricate ingredients for high strength concrete piles with enhanced physical properties and spherical foam products. The waste LCD glass recycling technology is already developed to fabricate long and short fibers at commercial level. In view of these, future R & D on waste LCD glass materials is to be directed toward implementation of commercial materials recycling system therefrom.

국내 디스플레이 산업의 핵심기술과 글로벌 점유율은 세계 최고 수준이지만 폐 디스플레이의 재활용 관련한 전반적 기술은 매우 미흡하고 폐 디스플레이의 유리소재는 전량 매립하고 있는 실정이다. 본 논문에서는 폐 초박막 액정표시장치(Thin Film Transistor Liquid Crystal Display) 유리를 고강도 콘크리트 파일 및 발포체의 원료로 재활용 하는 연구, 초박막 액정표시장치 제조 공정에서 발생하는 불량품인 파유리를 장섬유 및 단섬유 등으로 재활용 하는 연구 동향에 대하여 조사하였다. 폐유리를 재활용한 원료 성분은 고강도 콘크리트 파일과 발포체 원료로 재료 재활용이 가능한 것으로 입증되었으며 특히 콘크리트 파일의 경우 기존 제품보다 향상된 특성을 나타내었다. 이외에도 파유리를 장섬유나 단섬유로 재활용 하는 기술은 이미 상용화 단계에 있으므로 향후 폐 디스플레이 유리 소재의 상용화 재활용 시스템을 구축할 수 있는 기술을 확립하는 방향으로 연구를 진행할 필요가 있다.
