The landfill treatment of kitchen waste is an anaerobic digestion treatment method, which can decompose organic matter into CH4 and completely dispose of the waste. It is a simple and convenient method to treat kitchen waste, but it is a non-renewable resource treatment method. Although this method can treat kitchen waste well, it will not leave the problem of residue treatment, but it only aims at eliminating garbage and cannot realize the recycling of kitchen waste; Secondly, landfill needs land, and land needs to be requisitioned to build landfill, which aggravates the shortage of land; Finally, this method is also easy to cause secondary pollution.

2, incineration method

Incineration is a physical treatment method, and it is also a method that resources cannot be used. Kitchen waste incineration has the advantages of high reduction rate and thorough harmless treatment, and the treatment facilities occupy a relatively small area. However, due to the high water content of kitchen waste, the incineration process requires a lot of fuel, and sometimes incomplete combustion will produce gaseous pollutants, polluting the environment, and burning kitchen waste will not produce renewable resources.
