Incinerators have two stages of combustion, primary combustion chamber (650°C), secondary combustion chamber (over 1050°C). Some furnaces have an additional combustion chamber after the secondary combustion chamber to increase the efficiency of burning toxic gases. Incinerators are equipped with exhaust gas treatment systems, including heat exchange (cooling by air or water), absorption (fogging/alkaline solution) and possibly adsorption (activated carbon).

  • Applicable in Hanoi, Binh Duong, Dong Nai, Quang Ngai, Thanh Hoa... with a capacity of 10,000 - 15,000 m3/burial pit.
  • Advantages: Large capacity, relatively cheap treatment cost, can treat hazardous waste in the future, has a closed roof, has a system to collect leaking water.
  • Disadvantages: Takes up space. Not thoroughly treated, risk of leakage after closing the pit, must ensure strict conditions.
  • Currently, the Ministry of Natural Resources and Environment is preparing to develop National Technical Regulations on hazardous waste landfills, focusing on regulations on operation, monitoring and closure of landfills
  • Applied in many units to reduce the toxicity and mobility of waste.
  • Process: mix waste with additives to minimize the possibility of spreading hazardous waste and reduce the toxicity of hazardous waste from the waste mass. Then, use additives to change the physical nature of the waste.
  • The product after solidification can be used for internal purposes of the facility...
  • Advantages: Simple implementation, simple equipment, low cost...
  • Disadvantages: limited amount of hazardous waste to be treated...
