본 연구는 가스화용융 시스템을 활용한 폐차 냉매의 친환경 파괴 기술개발을 목표로 하였다. 실증규모(생활폐기물 100톤/일) 가스화용융 시스템내 냉매를 주입할 수 있는 주입장치를 개발 및 제작하였으며, HFC-134a 주입량에 따른 냉매 분해효율 및 유해가스 특성을 고찰하였다. 분해효율은 3 kg/hr 냉매 주입시 99.995%이었고, 18시간 동안 유해가스 연속 측정 및 샘플링 측정결과, CO, SOx, NOx, HCl, HF 등의 유해가스는 환경법규를 만족하였고, 특히 냉매파괴 발생 HF는 0.1 ppm으로 법적 기준치 2ppm에 비해 미량으로 검출되었다. Destruction of HFC-134a from ELV (End of Life Vehicle) were determined in a gasification-melting demonstration system of municipal solid waste (100ton/day). The injection system has been developed for the uniform injection of HFC-134a to the gasification-melting system. The destruction characteristics of HFC-134a and analysis of exhaust gases have been performed. The destruction efficiency was 99.995% for HFC-134a feeding of 3 kg/hr and the exhaust gases such as CO, SOx, NOx, HCl and HF satisfied the environmental standards.

In order to improve the recyclability and to reduce the recycling cost and time, the disassembly technology should be systemized because the worn out products can be reused or recycled after disassembly processes. This paper attempts to propose the integrated CATIA-based DfD (Design for Disassembly) support system to promote the disassemblability of products. The system is composed of two modules; evaluation of disassemblability, generation of DID alternatives. The disassemblability of current vehicle is evaluated to identify the weak point in terms of disassembly using the DELMIA and developed evaluation system. Furthermore a new expert system is developed to propose the optimal redesign rule and principle for generating the DfD alternatives. In order to generate the DfD alternatives, a CATIA-based design support system is implemented. The system can provide quick results and ensure consistency and completeness of the redesign alternatives.
