Due to historical and human factors, there are a huge number of simple or non-standard landfill sites in our country. These landfill sites have problems such as exposed garbage piling, generating a large number of mosquitoes, serious pollution from leachate, and random discharge of polluting gases, which pose a serious pollution threat to soil, groundwater, etc. In addition, the irregular accumulation of landfill gases leads to explosion hazards. Therefore, the treatment of existing landfills in a simple or informal manner is extremely urgent.

 

Why should stale garbage be recycled and reused?

 

First, reducing waste can obtain land resources and enable landfills to be reused. Through the comprehensive garbage management process, the volume of garbage is reduced, and at the same time, the landfill site is ecologically restored, thus allowing the original land to be redeveloped. Under the increasingly tight situation of land resources, the treatment of stale waste from the original closed landfill sites has great market potential.

 

Second, the harmless treatment of garbage can eliminate the pollution caused by landfill sites to the surrounding environment and groundwater. Especially for the original large number of non-standard landfill sites, due to the lack of effective protective measures during operation, the pollution such as water, air and machine odor produced not only has a serious impact on the lives of surrounding residents, but also poses a threat to groundwater. Through the comprehensive management of stale garbage, the original pollution sources have been effectively eliminated, the ecological environment has been improved, and significant environmental and social benefits have been achieved.

 

Third, the resource utilization of garbage can obtain recyclable resources and achieve the recycling of resources. Through comprehensive management and resource utilization processes, a large amount of humus soil can be obtained, which can be used as planting soil for green flowers and trees, covering soil for the soil layer of landfill sites, and as a purification substrate for biological filtration pollutants, etc. If the resource products of landfill old and decomposed garbage, which are abundant in resources, can be used to replace the above materials, it will have an incomparable superiority in economic and environmental benefits
