Life Cycle Assessment–based Comparative Evaluation of Originally Manufactured and Remanufactured Diesel Engines

摘要: Life cycle assessment (LCA) enables us to estimate potential resource and energy consumption as well environmental emissions resulting from various activities within our economy. The present LCA intends analyze the of entire life an originally manufactured diesel engine compared with its remanufactured counterpart. Further, article attempts identify processes in manufacturing remanufacturing cycles that contribute most impacts. Six impacts were assessed this study: global warming (GWP); acidification (AP); eutrophication (EP); ozone depletion (ODP); photochemical creation (POCP); abiotic (ADP). results show could reduce 66% consumption, original manufacturing. greatest benefit related impact is regard ODP, which reduced by 97%, followed EP, GWP, POCP, AP, ADP, can be 79%, 67%, 32%, 25%, respectively. In manufacturing, production materials brings about larger impacts, especially EP whereas transportation contributes POCP. situation similar for remanufacturing. Production components exhibit same amount GWP impact. remanufacturing, reverse logistics old engines lesser than other stages, except
