Abstract: Dumping of solid waste and its open burning have not just polluted the earth but also have made a loss of potential energy contained in it. The proposed study aims to conceptualize the design and analysis of a Waste-to-Energy based polygeneration renewable energy system with no outage in order to increase social hygiene at the lowest economy, environment-friendly, and energy efficient. The optimization of system is done with the help of HOMER@ Pro software. The result shows that the optimal solution can supply 59,330 kWh/year of electricity, 17,842 kWh/year of heat with 19.89 °C increase in temperature (used for Space heating), 57.51 kg/day cooking gas, 269.31 kg/day transport fuel (biogas), and 1395 kg/day compost with cost of energy Rs. 5.49/kWh and net present cost of Rs. 38.87 lakh. The emission analysis shows that the system generates only 5469 kg/year of CO2 emission and avoids 40,772 kg/year of CO2 emission, earns yearly carbon credit of 40.7 units. The sensitivity analysis shows that the increase in the capacity shortage decreases reliability and the economic factors except for O&M cost and increases the renewable energy factor and the absence of continuous energy supply. Moreover, the proposed model approaches sustainable development goal 6 & 7.
