냉장고 폐기단계의 환경성 및 비용분석

Abstract

A systematic methodology for identifying improvement factors based on the analysis of environmental aspects with LCA and economic aspects with cost analysis during the disposal phase of a product was proposed in this study. The proposed methodology was applied to a discarded refrigerator. The improvement factors requiring highest priority include incineration of PUF and incineration of other plastics. Those requiring higher priority include recycling of steel and ABS with respect to the cost aspect, and refrigerant, R-134a to the environmental aspect. Weight of steel and ABS is the attribute of the refrigerator that causes problems in the cost aspects. Improvement strategies would include design for light weighted product and optimization for the waste disposal pathway. Global warming and recycling potential are two major attributes of refrigerant that cause problems in the environmental aspects. Improvement strategies would include the development of recycling technology, use of recyclable materials, and use of natural refrigerant that does not cause global warming.
