A mass balance of process was calculated by using the analysis of basic unit and environmental assessment of all the processes of Busan fashion color industry cooperative that operates a combined heat and power plant and a bio treatment plant. The mass balance for the combined heat and power plant was done, based on boiler and water treatment processes while each unit reactor was used for the bio treatment plant. From the results above, a resource recycle network, a treatment flowchart for food waste water/wastewater treatment and a carbon reduction program were established.

As a practical means to upgrade urban sustainability, this paper focuses on resource cyclical systems concerned with the waste of electric and electronic equipment (WEEE) in Korea. Borrowing System Dynamics concepts and approaches, it examines behavioral changes of WEEE dynamics to observe whether the existing management methods can be readjusted. The measurement is based upon both reuse and material and thermal recycle simulation works in the individual stage of WEEE discharge, collection, and treatment, going beyond the traditional recycle-only customs. This research estimates that the newly introduced Extended Producer Responsibility (EPR) system would definitely exert a significant impact on the final stage of WEEE treatment, decreasing the final treatment volume in the first half of the research period. The trend, nonetheless, would be reversed in the second half, mainly owing to the additional waste volume originated from the local government and recycling center. Sensitivity analysis poses, among others, that the local government-supported reuse center should take charge of a pivotal role in the long run. The research also shows that sufficientand necessary conditions for the WEEE management and treatment should be given to the combined efforts, both from the private sectors and the public domains. Based on these research findings, the paper recommends that key stakeholders including the producer and the public organizations should devise how to jointly carry out specific agenda centered around partnership or network buildings.

오늘날 기업들에서는 폐기물을 감량화, 재활용, 재이용하기 위해 노력하고 있다. 폐기물이 재활용되고 있지만, 많은 폐기물이 소각 또는 매립되고 있다. 이러한 문제를 해결하기 위하여, 산업단지를 중심으로 폐기물을 재활용하기 위한 다양한 사업이 진행 중이다. 하지만, 폐기물 재활용에 대한 정보의 부족으로, 재활용가능 폐기물은 여전히 소각되거나 매립되고 있다. 이러한 배경 하에, 본 연구는 기업의 폐기물을 원료로 재활용하는 폐기물 자원순환에 의해 저감되는 탄소배출량과 경제성 평가방법을 제시하고자 한다. 그 평가방법을 적용하여 폐합성수지와 폐유기용제의 자원순환사례를 평가하였다. 재활용과 소각 측면에서 환경적 및 경제적인 측면을 분석하였다. 폐플라스틱을 원료로 재이용함으로써, 탄소배출량은 2009년에 1,0705톤, 2010년에 1,234톤이 저감되었으며, 비용은 2009년에 6.57억원, 2010년에 7.55억원이 저감되었다. 폐유기용제를 재활용 할 시에는 2010년에 7.3톤, 2011년 5.6톤의 탄소배출량이 저감되었으며, 비용은 2010년에 1,591만원, 2011년에 1,218만원이 저감되는 것으로 나타났다.
