Abstract: In this study, a novel multi-generation system comprising of municipal solid waste powered Rankine cycle, solar parabolic trough collector, absorption chiller, electrolyser and reverse osmosis, all integrated together to produce useful outputs namely electricity, drinkable water, cooling, warm water, heating, hydrogen and dry air, is proposed and thermodynamic assessment is carried out. Energy analysis and exergy analysis has been carried out by setting up multiple parameters. System performance for different districts in Karachi is then investigated by performing a parametric study by changing system parameters such as municipal solid waste input, calorific values, and ambient temperature, the corresponding changes in system outputs and efficiencies are then compared. The system's average energy and exergy efficiencies are found out to be 88.6% and 60.3% respectively.
