Incineration technology can help reduce waste in landfills by burning it and generating energy. The process involves four steps: pre-treatment to increase waste's energy value, combustion following the 3 T principles (temperature, turbulence, time), energy recovery from heat produced, and flue gas treatment to reduce air pollution. The key conditions for efficient combustion are waste residence time under 60 minutes, gas residence time over 2 seconds, and gas temperature above 850°C. Overall, incineration can reduce waste volume, produce energy, and minimize air pollution.
