Greenhouse Gas Emission Control and Development Prospect of Landfill in China
The development of domestic waste landfill treatment in China was analyzed.The results showed that the number of sanitary landfills and the amount of domestic waste landfill in China showed a downward trend from 2010 to 2022.The proportion of municipal and county solid waste sanitary landfills in all landfills had increased year by year,and the proportion both reached more than 98%in 2022.In the process of landfill treatment development,landfill leachate treatment is one of the weak links and needs to be paid attention to.At the same time,methane emitted from landfill is an important source of greenhouse gas emissions in the world,and landfill gas recycling should be actively carried out.In recent years,although the primary landfill treatment has gradually been replaced by the incineration of domestic waste to power generation,the landfill is still an essential infrastructure for domestic waste treatment.Moreover,it is necessary to ensure the reasonable remaining capacity of the landfill,which could avoid the construction of emergency landfills and improve the toughness of domestic waste treatment.
