Abstract

최근 나노기술의 급격한 발전은 산업 분야에 새로운 활용 가능성을 제시하고 있다. 그러나 나노물질의 연간 생산량 증가와 함께, 비의도적인 환경 노출이 야기되고 있다. 따라서 지속적인 나노기술의 발전을 위해서도 나노폐기물에 관한 효과적인 관리가 필요하다. 나노폐기물 처리의 최종 단계는 바로 소각시설을 이용하는 것으로 보고 있다. 나노물질의 소각처리에 관한 문헌자료가 부족하지만, 일부 선도적인 연구자들에 의하면 소각시 나노물질의 대기노출은 억제되지만 바닥재는 결국 매립되어 나노물질은 잔존하게 된다는 것이다. 아직까지는 소각장내 나노물질의 거동과 다양한 질문거리가 남아 있지만, 무엇보다도 소각을 통한 나노폐기물 처리가 인간 및 환경 영향을 최소할 할 수 있는 안전하고 효과적인 나노물질 처리법인지가 검토되어야 할 것이다. Rapid growth in nanotechnology promise novel benefits through the exploitation of their unique industrial applications. However, as increasing of production amount of nanomaterials, their unintentional exposure to the environment has been caused. Therefore, there is a need for effective management of nanowaste to the sustainable nanotechnology. One possible endpoint at the environmental exposure scenario for nanowaste treatment is incineration. Although a few study on the incineration of nanomaterials was reported, pioneering researchers found that although it is possible to incinerate nanowaste without releasing nanoparticles into the atmosphere, the residues (bottom ash or slag) with nanomaterials eventually end up in landfills. Though there are still many questions to understand the fate of nanomaterials in incinerator, firstly we have to study whether nanowaste treatment via incineration is safe to human and environment.
