LCA-Based Comparative Evaluation of Newly Manufactured and Remanufactured Diesel Engine

Life Cycle Assessment (LCA) enables to estimate the potential materials, energy resources, and environmental emissions resulting from various activities in our economy. The present study intends to analyze the energy consumption and environmental emissions in the entire life cycle of originally manufactured diesel engine compared with its remanufactured counterpart. Furthermore, the paper attempts to find out the largest energy requirement and the severest environmental emissions contribution stage. This LCA is conducted by software E-Balance and data collection refers to the database CLCD. The result shows that energy consumption and environmental impacts are considerably reduced for the remanufactured engine compared to a newly manufactured engine. the greatest benefits are EP which is reduced by 90.57%, followed by ODP, PED, GWP, AP which can be reduced by 75.15%, 70.33%, 68.92%, 67.65% separately.
