Waste-to-energy facilities are compared to see which is the best at turning waste into energy. Municipal solid waste incinerators in Europe can handle a wide range of waste without needing special treatment. Other methods, like using waste in cement kilns, need the waste to be prepared first. In Germany, all facilities have similar emission limits. Using waste for energy can be cost-effective, especially if energy prices go up. There is enough capacity in Europe to burn organic waste instead of burying it. Some places have too many waste-to-energy facilities, leading to lower prices. Burning waste for energy helps reduce greenhouse gas emissions compared to burying it.
