Investigation on the Comparative Life Cycle Assessment between Newly Manufacturing and Remanufacturing Turbochargers

摘要

This paper statistically analyzed and compared the energy consumption and pollutant emissions of newly manufactured turbochargers with that of remanufactured ones based on the Life Cycle Assessment (LCA) methodology and on-site investigation. The hotpots of environmental impacts and the processes in newly manufacturing and remanufacturing were identified. The results show that, remanufacturing process could notably reduce 82.55% of primary energy demand (PED) and 90.84% of ozone depletion potential (ODP); and global warming potential (GWP), acidification potential (AP), eutrophication potential (EP) and photochemical ozone formation potential (POCP) could be reduced by 73.33%, 11.88%, 59.79% and 73.19%, respectively.
