LCA에 있어 영향정량화 인자의 산정과 적용

환경오염 정도에 따라 각국의 환경보호정책이 달라지기 때문에, LCA의 표준화에도 각국의 환경오염 정도를 고려해야한 다. 본 논문은 이러한 생각을 바탕으로 국내 환경오염정도와 환경기준을 이용하여 영향 정량화 인자를 개발하였다.

환경부하의 카테고리별 가중치와 카테고리내 영향항목의 가중치를 이용하여 영향정량화 인자를 계산한 결과, 수질오염 등 지역적 환경오염의 정량화인자가 비교적 높은 값을 나타내었다.

구해진 정량화 인자를 이용하여 종이기저귀와 천기저귀 목록분석자료의 영향평가에 적용한 결과, 종이기저귀가 더 환경을 오염시키는 것으로 평가되었다.

The purpose of LCA is to quantify resources, energy consumption and environmental loads for environmental improvement and to pursuit finally the sustainable development and balance of ecosystem. Because strategies for envrionmental protection are different from each country depending on the environmental situation, these must be considered in LCA standardization of each country.

Theories of impact quantification criteria were examined and the degree of environmetal impact was calculated on the basis of level of each impact category.

Impact quantification criteria calculated on the basis of Korea environmental level were different from each criterium calculated by each method and environmental level of each country. High criteria could be obtained in the case of highly polluted region. Therefore, if impact quantification criteria is standardized uniformly regardless of environmental level of each country, it could be underestimated for improving properly the regional environment.

Children diaper was analyzed as a case study for LCA and environmental loads were unified to make enviroment load index using impact quantification criteria on the basis of environmental level of Korea.
