Abstract

This study introduces an energy superstructure for waste management in a large-scale farm. It selects the optimal technologies by optimizing the productivity factor and greenhouse gas (GHG) emission functions. The optimization results show that the optimal solution to maximize the efficiency factor is to use a biogas engine that produces a significant amount of 1695.825 GWh of electricity and 1893.11 GWh of heat in a year. Also, one of the advantages of this scenario is that it is economical and has a good return on investment, which attracts investors to it. On the other hand, the optimal solution to minimize GHG emissions do by using combined heat and power based on gas turbine and carbon capture storage; this scenario emits 114.585 Kton of carbon dioxide per year. It is worth noting that this amount, based on waste management, as well as electricity and heat production, reveals the high value of bioenergy potential.
