Abstract: The energy requirement in the present world has been hastily boosted in the last few decades and meeting the demands in the current situation has become a great challenge among developing countries, especially a developing country like India habituating world most of the population. When the country's standard of living rises, economic expansion, and industrialisation it becomes more crucial to explore other possible ways for the generation of the power to synchronize the pace. This study aims to review some of the techniques using waste-to-energy which can be used as an alternative to electricity generation. Waste-to-energy can be turned into one of the most sustainable and efficient methods of managing waste while simultaneously generating clean and renewable energy. The incineration technique is one of the most used techniques across the globe. The WtE concept is a ground-breaking strategy that has the potential to lessen human environmental impact. The waste substances are converted into energy at the WtE facility using a heating panel. The electricity created by the WtE plant may be utilized to power homes, companies, and other organizations, lowering the demand for traditional non-renewable electricity. The WtE facility also contributes to a reduction in the quantity of trash transferred to landfills. The WtE plant would minimize the quantity of greenhouse gases like CO2, CO, SO2, NO2, and heavy metals like mercury discharged into the environment by lowering the amount of garbage transported to landfills. Furthermore, the WtE facility would be able to minimise the amount of energy required to transport trash to and from landfills.
