“…Recently, the emergy analysis (EmA) has been used in a wide range of research fields. The EmA research studies were concluded as the evaluation of the agriculture productions ( Wilfart et al., 2013 ; Bergquist et al., 2011 ), industry ( Li et al., 2016 ), building and construction ( Cristiano and Gonella, 2019 ; Cheng and Cheng, 2017 ), energy storage systems ( Yazdani et al., 2019 ), urban sustainability ( Lee and Braham, 2019 ; Hossaini and Hewage, 2013 ), and modern renewable systems ( Yang and Chen, 2014 ; Siracusa et al., 2007 ). Some of these studies were performed to assess a proper way for the MSW management.…”

This paper performs an emergy analysis (EmA) to compare two real power plants include a conventional natural gas steam power plant (NGPP) with one that burns municipal solid waste (MSWPP). For this purpose, the EmA is used to investigate the sustainability, renewability, environmental impacts, and economic issues. The capacity of the NGPP and MSWPP are 247.5 and 3 MW, respectively. Results from this study show that the percent of renewability (PR) and emergy sustainability index (ESI) of the MSWPP are much more than those of the NGPP. The PR and ESI of the MSWPP are 46.81 and 1.65, while for the NGPP are 5.01 and 0.05, respectively. It is proved that the MSWPP is more efficient and has the better environmental impacts compared to the NGPP. Moreover, a hypothetical MSWPP with the same electricity output of the NGPP is studied using the EmA. A more efficient system with the higher PR and ESI is observed compared to the other case studies. Beside of these advantages, use of the MSW has other benefits such as reducing the greenhouse gases released in the atmosphere, saving fossil fuels, low land area required compared to the landfill, speed and ease of disposal, and production of clean and useful ash.
