In 2020, Shanghai will basically realize zero landfill of primary domestic waste. Although landfill is still one of the main means to treat municipal solid waste nationwide, in a big city like Shanghai, landfill, a relatively backward means of garbage disposal, is gradually being eliminated.
As an effective alternative to landfill, garbage incineration has the characteristics of less land occupation, obvious emission reduction effect and waste heat utilization. It has been widely used in developed countries and regions, and is being gradually implemented in China. In 20 16, the Ministry of Housing and Urban-Rural Development jointly issued the Opinions on Further Strengthening the Incineration Treatment of Municipal Domestic Waste, proposing that by 2020, the incineration treatment capacity of municipal domestic waste in China will account for more than 50% of the total treatment capacity.

Liu Jianguo, a professor at Tsinghua University Institute of Environment and director of the Institute of Solid Waste Control and Recycling, said that with the gradual promotion of waste sorting, China will also speed up the construction of wet waste treatment facilities. It is predicted that in the next few years, biological treatment facilities will become an indispensable part of the whole garbage treatment technology pattern in China.
If dry and wet garbage is not separated, garbage will easily produce more toxic and harmful substances to pollute the environment because of its high water content and insufficient combustion. Therefore, whether it is landfill reduction or incineration standardization, it is necessary to carry out front-end classification of garbage.
