In this study, we evaluate the eco-efficiency for recycling processes of Busan Resources Recycling Center for each year from 2010-2012. It analyze the impact of global warming on the power consumption by Life Cycle Assessment. Also calculate the economic value by net profit components those are sales amount and electric charge in accordance with the process operation. On the basis of these results, each of the eco-efficiency Factor analysis and dynamics analysis of 2011 and 2012 as the base year to 2010 are performed. As a result, the impact of global warming in all the recycling processes is increased by increasing power consumption 2010-2012. But net profit is decreased. In addition, the eco-efficiency of all the recycling processes is decreased and analysis result of the eco-efficiency trends is located on the Fully non Eco-efficiency (--) level. Therefore, all the recycling processes are necessary improvement for power consumption reducing and net profit increasing to further the environmental and economically sustainable direction.

본 연구에서는 우리나라 미이용 자원의 유효이용 즉, 리싸이클링의 동향을 조사하기에 앞서 다양한 자원의 전체현황을 파악하려고 노력하였다. 그러기 위해서 자원수급의 세계적인 추세를 논하였고, 우리나라와 비교 검토하기 위해서 일본의 주요금속의 머티리얼 흐름을 조사하였다. 끝으로 우리나라 금속자원, 에너지자원 및 광물자원의 수급동향을 탐색, 고찰하였다.

PURPOSES : This study aimed to analyze economic effect of recycled aggregate production on job-site airport pavement. METHODS : The validation of site recycling for waste concrete as economic efficiency is analyzed through the case study of site recycling at an O airport pavement construction. The break-even point for the cost of site recycling was estimated according to two different waste concrete processing methods such as job-site recycling and processing on commission (or plant). RESULTS : Job-site recycling cost decreases as the use rate of job-site recycled concrete aggregate increases, or the amount of concrete waste increases, but transporting distance decreases. It was shown in an O airport case that as the use rate of job-site recycled concrete aggregate exceeds 61.4 %, the job-site recycling cost is cheaper than the processing cost on commission. CONCLUSIONS : The results of this study can utilize basic data of feasibility for site recycling of waste concrete on airport pavement construction.

우리나라의 도시광산 재자원화실태와 전망을 파악하기 위하여 금속소비량을 산출하였다. 년간 금속소비량으로부터 금속 축적량을 추정할 수 있고, 도시광산자원을 전망할 수 있다. 금속소비량을 산출함에 있어 다양한 자료 즉 비철협회, 철강협회, 관세청 HS 코드, 연구용역 보고서, 학술회의자료 및 생산회사 탐문자료 등을 인용하였다. 도시광산개발의 요건(key point)을 설명하기 위하여 T.E.Graedel에 의해서 작성된 표(Principle Uses and Recycling Potential of Metals in the Periodic Table)를 인용하였다.
