  • 일반적으로 cross-link된 열경화성 에폭시수지는 유기용매에 용해되지 않고 열에 용융되지 않는 특성이 있다. 따라서 에폭시수지가 사용된 물질, 특히 탄소섬유강화플라스틱(carbon fiber reinforced plastic, CFRP)은 재활용이 어렵고, 사용 후 폐기물 처리에 막대한 비용이 소비되고 있다. 본 원고는 열경화성 에폭시수지 응용물 중 CFRP의 재활용을 중심으로 한 친환경적 재활용 기술에 관하여 정리하였다. 특히, CFRP의 구성요소인 탄소섬유(CF)와 기지재인 에폭시수지를 모두 재활용 할 수 있는 화학적 방법에 관하여 보고한다. 더 나아가 열경화성 에폭시수지의 화학적 분해물의 재이용기술에 관한 예를 소개한다.

  • Plastic packaging generates less problems than most consumers think, but how to develop the recycling market for plastic waste materials will be critical for the plastic manufacturers. To do this, government must provide enough facility in order to balance economics for plastic recycling market and to run successful recycling programs. Various cost effective recycling technologies have been introduced and also have significant role to boost use of recycled plastics, but this could be only with well organized recycling policy.

  • Depending on the states of polyurethane scraps generated in the production sites of polyurethane or recycling center of polyurethane scraps, appropriate recycling technologies can be employed for the recycling of resources. In this study, recycling technologies for the polyurethane scraps were classified into physical recycling, chemical recycling, and energy recycling and reports in the literatures were discussed.
