The process of converting harmful waste into usable energy is called "waste-to-energy" or "energy from waste." This process involves the combustion of waste materials to generate electricity, heat, or fuel. The main goal is to reduce the volume of waste while simultaneously recovering energy that can be harnessed for productive use. By employing various technologies such as incineration, gasification, or anaerobic digestion, waste-to-energy facilities can minimize landfill usage and contribute to sustainable waste management practices. This method not only helps address waste disposal challenges but also supports the transition to greener energy solutions, contributing to environmentally friendly energy production.
