This study was performed as one part of “Basic scientific problems of machinery and equipment remanufacturing” funded by National Basic Research Program of China. We are indebted to the endorsement from Shenyang Blower Work Group Co., Ltd and National Basic Research Program of China (Grant No. 2011CB013406 ).

As for the end-of-life phase, Ilgin and Gupta (2010) proposed five alternatives for typically discarded products. The environmental impacts of these alternatives (i.e., recycling, direct reuse, remanufacturing, repair, and landfilling) have been studied by many researchers ( Li et al., 2016; Zanghelini et al., 2014; Hischier et al., 2005 ). Various studies have previously reported that remanufacturing has least environmental impacts than other disposal options by reducing the materials and prolonging the service cycle. At present, the compressor remanufacturing in China is under a research sponsored by the National Basic Research Program of China. Although the compressors can theoretically be remanufactured, remanufactured compressors still cannot be used in China under currently undeveloped technologies because of the high demand for reliability and security. Thus, the disposal methods used for waste compressors are landfill and remelting at the end of the compressors' life cycle as presented in Fig. 2 .

N2 - A comprehensive assessment of the environmental performance of products in heavy industries is indispensable in unraveling the environmental pollution and resource shortage in the manufacturing industry of China. To quantify the environmental emissions and resource consumption in the holistic life cycle and identify the hotspots, this study applies the life cycle assessment to an 18.4 MW class domestic large-scale centrifugal compressor and compares the environmental impacts of the overall milled impeller and the welded impeller. Six environmental indicators—, namely, primary energy demand (PED), global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), ozone layer depletion potential (ODP), and photochemical ozone creation potential (POCP) are considered in this case study. Usage, raw material production, and manufacture are the top three contributors to the entire emissions and resource utilization. The environmental impacts comparison of impellers reveals that welded impeller is more environmentally favorable in terms of PED, GWP, AP, EP and ODP. Results of this study can provide a scientific basis for compressor manufacturers to minimize the environmental burdens from the life cycle perspective.
