Incineration

  Incineration is the use of high temperature (900 ~ 1000 ° C) to burn flammable or inert residual waste. This temperature is enough to burn combustible materials, leaving only dust and non-combustible materials. Unburned waste residues after incineration are usually inanimate and can be used as suitable fillers. In the vicinity of large cities, land resources are tight, and there is a general lack of landfill sites for waste disposal.
  After the waste is burned, it can reduce the volume, facilitate landfill, eliminate various pathogens, convert some toxic and harmful substances into harmless substances and recover heat. In recent years, incineration has become an important means for many countries to comprehensively utilize waste resources. It can achieve harmless emissions, basically eliminate waste in volume and release heat.
  Now, developed countries such as Europe and the United States are working hard to develop new energy sources for waste and use waste to incinerate electricity. From the perspective of environmental protection, there are also air pollution problems in incineration. The toxic gases emitted from incinerators include hydrogen chloride, sulfur oxides, nitrogen oxides, and PCBs. Therefore, the incineration exhaust gas must be treated twice. In addition, the total investment and operating costs of incineration are generally higher than the sanitary landfill and composting laws.
