According to thermodynamic calculations and experimental verification, dioxins undergo oxidation reactions at 800–950 °C, breaking down to form non-toxic aromatic hydrocarbons. The reaction pathway is as follows: https://pic4.zhimg.com/80/v2-139e84de582106f8899caf22074d7f94_720w.jpg https://pic2.zhimg.com/80/v2-7431846a6239cdbb07404cfc9d9c363f_720w.jpg In other words, the simplest and most direct way to reduce the formation of dioxins is to increase the temperature in waste incinerators, thereby ensuring that the dioxins are completely oxidized. In other words, as is often mentioned, \"maintaining a temperature inside the incinerator above 850 °C and ensuring that the flue gas stays inside the furnace for more than 2 seconds will enable complete decomposition of dioxins.\" However, whether it is waste incineration or waste pyrolysis, the temperature range is usually 400–750 °C. Raising the reaction temperature implies higher energy consumption and greater equipment requirements; relying solely on increasing the reaction temperature to control dioxin formation does not seem to be the best approach. In addition to raising the reaction temperature and controlling process conditions (3T+E technology), from the perspective of chemical engineering and technology, if dry and wet materials can be separated (to prevent contact between water vapor and chlorides), plastic and metal waste can be separated (to prevent the chlorine sources in plastics from coming into contact with metals that act as catalysts), and construction waste from household waste can be separated (to prevent silicon, aluminum, and chlorides from mixing), it is possible to halt the formation of dioxins by curbing the generation of Cl2. In other words, if waste sorting is done properly, it can **reduce dioxins generated during waste incineration. Source: Zhihu
