요약문

본 연구는 1차금속 제조업에서 발생하는 사업장폐기물에 대해 통계 방식에 의한 재활용과 물질흐름에 의한 실질재활용량을 분석하였다. 2019년도 1차금속 제조업에서 발생된 폐기물량은 34,304 천 톤, 재활용은 33,232 천 톤으로 재활용률은 96.9%이다. 그러나, 물질흐름분석에 의한 재활용 과정 중 새로이 발생된 잔재물을 적용한 결과, 실질재활용량은 29,115 천 톤으로 감소되었고, 순환이용률은 84.9%로 나타났다.

This study analyzed the recycling by statistical method and the actual recycling capacity by material flow for industrial waste generated in the Manufacture of basic metals. In 2019, the amount of waste generated in the Manufacture of basic metals was 34,304 thousand tons and recycling 33,232 thousand tons, with a recycling rate of 96.9%. However, as a result of applying the newly generated residues during the recycling process by material flow analysis, the actual recycling capacity was reduced to 29,115 thousand tons, and the recycling rate was found to be 84.9%.
