Abstract

This study analyzed the economic inducement effect of urban mining owing to the application of laser induced breakdown spectroscopy (LIBS) technology with input–output analysis by considering energy demand and CO₂ emission reduction, as well as production and employment. The estimation result showed that, as a result of the installation of LIBS facilities, the production inducement coefficient is 1.25, the value-added inducement coefficient is 0.46, the job inducement is 4.56 persons per 1 billion KRW, and the employment inducement is 3.74 persons per 1 billion KRW. Owing to the operation of LIBS facilities, the production inducement coefficient is 1.13, the value-added inducement coefficient is 0.50, job inducement is 6.35 persons per 1 billion KRW, and the employment inducement coefficient is 5.34 persons per 1 billion KRW. In addition, the application of LIBS technology can induce positive effects in urban mining with respect to energy demand and CO₂ emission reduction, as well as production and employment, by reducing 0.0003% of CO₂ eq. and 0.02% of the total energy input.

본 연구는 LIBS 기술을 적용한 도시광산의 경제 유발효과를 산업연관표를 이용하여 분석하였다. 특히 도시광산 산업이 폐기물 재생을 통해 경제 및 환경 관점의 편익을 기대하고 있으므로, 산업연관분석을 이용하여 도시광산 산업을 대상으로 유발효과를 추정하는 과정에서 생산유발, 고용유발 뿐만 아니라 에너지 수요·CO₂ 배출저감 측면에서의 효과도 추정하였다. 추정결과 LIBS 설비도입의 경우에 생산유발계수는 1.25, 부가가치유발은 0.46, 취업유발은 10억 원당 4.56명, 고용유발은 10억 원당 3.74명으로 나타났으며, LIBS 도입 도시광산산업 운영의 경우에 생산유발계수는 1.13, 부가가치유발계수는 0.50, 취업유발은 10억 원당 6.35명, 고용유발은 10억 원당 5.34명으로 나타났다. 또한 LIBS 기술도입 도시광산산업 운영의 경우에 우리나라 전체 에너지투입액의 0.02%를 저감하며, 0.0003%의 CO₂ eq.를 저감하는 것으로 나타나, LIBS 기술을 활용한 도시광산이 생산 및 고용 측면 뿐만 아니라 에너지 및 CO₂ 배출저감 측면에서도 긍정적인 효과를 기대해볼 수 있음을 알 수 있었다.
