Cleaner Production Management using Evaluation Method of Environmental Impact of ISO14001

ISO14001 환경영향평가방법을 이용한 청정공정관리 - Tourah Portland Cement회사를 중심으로 -

The unique method for evaluating the environmental impact, which is restricted to use in BS7750, was performed to determine the priority for reducing environmental loads in the cement process. Mass balance in the unit process was achieved, it was utilized to introduce the matrix method which are composed of two different evaluation's criteria by occurrence possibility and by occurrence results. The purpose of this paper is first to explain the matrix method in the practical plant and secondly to show the successful examples of enviromental improvement. Conclusively, the seriousness of environmental impact could be quantified in several different unit processes and suggested some progressive results obtained after process improvement.

영국 BS7750에서 사용하는 환경영향평가방법을 이용하여 시멘트공정내 환경영향심각도를 결정하기 위한 방법을 연구하는 데 목적이 있다. 이를 위하여 제조공정내 물질수지식을 세우고 제품과 폐기되는 환경오염원을 정량화하여 환경영향의 심각도를 발생가능성의 평가등급과 발생결과 평가등급을 종합한 환경 위해평가 메트릭스법을 도입, 환경오염원을 줄이기 위한 우선순위를 결정하였다. 환경영향평가결과, 각 단계별 공정의 환경영향의 심각도를 계량화할 수 있었으며 공정 개선후 얻어진 효과에 대한 결과를 청정관리 개선사례로 제시하였다.
