Abstract

Waste paint, one of the specified wastes in Korea, is currently treated entirely by incineration treatment method, and is hardly recycled compared to other wastes. Incineration treatment method also causes environmental problems such as air pollution. Thus, this study breaks away from the existing incineration treatment method of waste paint and switch to a method of pretreatment operation through evaporation, condensation, and thermal decomposition by temperature control. and then proposes a sustainable waste paint treatment process that can be recycled as an alternative energy heat source. If a new method of disposing of waste paint and technology for recycling are developed and disseminated, it is expected that the effect will be large from an economic and environmental point of view.

국내 지정폐기물 중 하나인 폐페인트는 현재 전량 소각 방법으로 처리되고 있으며, 다른 폐기물에 비해 재활용도 거의 이루어지지 않고 있어, 자원이 부족한 우리나라에 엄청난 자원의 손실뿐 아니라 소각으로 인한 에너지원의 낭비, 그리고 소각 시 발생하는 대기오염 등의 환경문제도 유발하고 있다. 이를 위해 본 연구에서는 기존의 폐페인트의 소각처리법을 탈피하여, 온도 조절에 의한 증발·응축, 열분해를 통해 전처리 조작하는 방법으로 전환하고, 이때 발생하는 잔재물을 활용하여 일정한 형상(과립형 및 분말형)으로 성형한 후 이를 대체에너지 열원으로 재활용할 수 있는 친환경(지속가능한) 폐페인트 처리프로세스를 제시하고자 한다. 폐페인트를 처리하는 새로운 방법과 재활용하는 기술개발이 이루어지고 보급된다면 환경적·경제적 면에서 그 효과가 클 것으로 기대한다.
