WTE offers a comprehensive approach to waste management by addressing multiple facets of the waste problem. It reduces the volume of waste sent to landfills, which helps conserve land resources, minimize methane emissions (a potent greenhouse gas) from decomposing waste, and reduces the need for new landfill construction. Incineration also recovers energy, which contributes to the diversification of the energy supply, thereby decreasing reliance on fossil fuels and reducing greenhouse gas emissions from power generation. Additionally, WTE facilities can recover valuable materials, such as metals from the ash, that would otherwise be lost in landfills. This approach is more sustainable than the traditional methods of waste disposal. In South Korea, where space is a premium, WTE is a particularly attractive option because it significantly reduces the volume of waste. WTE is not just about burning waste; it's about integrated waste management. The facilities are designed to handle various types of waste, optimizing energy production. The technologies employed are constantly improving, focusing on reducing environmental impact. Modern facilities often include advanced air pollution control systems, which reduce emissions of harmful pollutants, such as particulate matter, nitrogen oxides, and sulfur oxides. The energy generated is used for electricity generation, heating, and other industrial purposes. This integration results in a system that is both environmentally and economically beneficial.
