매연저감장치(DPF)의 전과정 분석을 통한 입자상 대기오염물질 저감효과 분석

초록

The present study aims to assess the environmental impacts of 1EA diesel particulate filter (DPF) manufacturing and particulate matter reduction using the life cycle assessment (LCA) analysis. To achieve this objective, the pollutant amounts emitted from the manufacturing process of DPFs were compared with those reduced by attaching to the produced DPFs and production equipment following the entire production process. The comparative analysis of emissions from the DPF manufacturing process and reduced particulate air pollutant amounts during the production process revealed particulate air pollutants emissions of 86 kg during the DPF raw material acquisition and manufacturing process. Whereas the total amount of particulate air pollutants reduced by DPFs over three years of production was 2,940 kg, indicating a reduction effect on particulate air pollutants in the entire production process except for the disposal stage. In addition, the analysis result of global warming obtained using the LCA analysis indicated emissions of 11,700 kg CO2-eq from the manufacturing process of 1EA DPA.
