Abstract

Waste explosives such as useless ammunition discharged from the military and coproduced useless explosives during the manufacturers production process have been continuously produced. These are difficult to dispose with normal waste treatment facilities due to the dangers of fire and explosion. An open burning or an open detonation at military designated disposal facilities is a classical treatment method for the dangerous explosives. The classical method raises various environmental problems by the emission of hazardous materials. An air pollution by the emission of hazardous gases such as SOx and NOx, soil and water contaminations by the accumulation of non-biodegradable heavy metals, are representative pollution examples. To overcome these problems, various processes for eco-friendly waste treatment methods have been developed, and some processes have already been operated in some countries. In the current report, various eco-friendly disposal processes for waste explosives or harmful materials, and their advantages and disadvantages are documented to suggest future development directions for reducing the hazardous substances by the treatment processes.

군에서의 폐탄약 및 제조업체에서 생산 중에 발생되는 불용화약 등 폐화약류는 지속적으로 발생되고 있다. 이들은 화재, 폭발 등을 유발하는 화약류의 위험성으로 일반 폐기물 처 리시설에서는 처리가 어려우며, 지정된 폐기처리시설에서 야외 소각 및 기폭처리를 하는 것이 고전적인 폐기처리 방법이다. 야외에서의 소각 및 기폭을 통한 폐기처리시에는 SOx, NOx와 같은 유해물질의 배출에 의한 대기오염, 중금속 및 난분해성 물질로 인한 토양 및 수질 오염 등 다양한 환경문제를 유발시킨다. 이러한 환경문제를 극복하기 위한 친환경적인 다양한 폐기처리 방안이 개발되고 있으며, 일부 국가에서 운영중에 있다. 본고에서는 폐화약류의 다양한 친환경적인 폐기처리 공정 및 각 공정에 있어서의 장, 단점을 소개하여 폭발성 위험물 및 유해물질처리의 향후 연구방향을 제안하고자 한다.
