본 페이퍼에서는 기업이 환경경영을 진행함에 있어서 환경부하를 저감하고 원가를 절감하는데 유용한 의사결정 정보를 제공하는 회계적 분석기법인 '물질흐름원가회계(Material Flow Cost Accounting; MFCA)'에 대해 살펴보고 그 유용성 과 활용방안을 모색해 보고자 실제 국내 자동차 부품을 생산하는 중소기업에 적용하여 보았다. 본 사례는 산업자원부 '한국 생산기술연구원'의 국가청정생산지원센터가 지원한 '자동차산업의 중소기업형 통합환경경영(S-IEM) 모형 구축 및 적용사 업의 일환으로 수행된 것이다.

Abstract

LCA study was carried out to compare different treatment methods of livestock excreta in Korea such as aerobic composting and anaerobic digestion. The potential life cycle impact of the aerobic composting process is 3.29E-06pt and anaerobic digestion process is 6.63E-07pt at the level of weighting. The environmental impacts from livestock excreta treatment processes are influenced remarkably by electricity use. And, global worming(57%) and abiotic resource depletion(35%) categories indicates key issues among the overall impacts. In order to assess the environmental impacts and identify key issues of each treatment method for livestock excreta, additional studies is called on to fulfill.
