Due to historical and human factors, there are a huge number of simple or informal landfills in China. These landfills have problems such as exposed garbage, large amounts of mosquitoes and insects, serious pollution from leachate, and arbitrary discharge of pollutants, which pose a serious threat to soil, groundwater, and other pollutants. The irregular accumulation of landfill gas also leads to explosion hazards. Therefore, the management of simple or informal existing landfills is urgent.

Why is it necessary to recycle and reuse aged garbage as a resource?

1、 Reducing waste can obtain land resources and enable the reuse of landfills. Through the process of comprehensive waste management, waste can be reduced in volume, while the landfill site can achieve ecological restoration, so that the original land can be redeveloped. In the increasingly tight situation of land resources, the treatment of stale garbage in existing sealed landfill sites has great market potential.

2、 Harmless disposal of garbage can eliminate the pollution of surrounding environment and groundwater caused by filling up the site with garbage, especially the pollution caused by the lack of effective protective measures during the operation of a large number of informal landfills, such as water, gas, machine odor, etc., which not only seriously affects the lives of surrounding residents, but also poses a threat to groundwater. Through the comprehensive management of stale garbage, the original sources of pollution have been effectively eliminated, the ecological environment has been improved, and significant environmental and social benefits have been achieved.

3、 Garbage resource utilization can obtain recyclable resources and achieve resource recycling. Through comprehensive management and resource utilization processes, a large amount of humus soil can be obtained, which can be used as cultivation soil for greening flowers and trees, cover soil for landfill sites, and biofiltration pollutant purification substrates. If resource rich landfill aged waste resource products can be used to replace the above data, it will have unparalleled advantages in economic and environmental benefits.
