What are the simple and effective ways to dispose of garbage?

Different wastes have different disposal methods.

General speaking, there are generally three methods: sanitary landfill, incineration and composting.

1. Sanitary landfill is currently one of the largest methods of disposing of waste, and it is also the last resort. Because no matter what method is used, there will be some substances that cannot be recycled and processed, and these wastes can only be disposed of by landfilling. But landfill will waste a lot of land resources, and there is a hidden danger of secondary pollution (exudate contaminates the surrounding soil and groundwater).

2. The incineration method is to burn the garbage into ash and slag at high temperature and then transport it to the landfill for landfill. It occupies less land, reduces the amount of stars, can completely eliminate pathogens, and can recover waste heat for heating and power generation, but the incineration method invests It is large and produces a large amount of air pollutants (such as heavy metals, CO, HCl, dioxins, etc.) during the incineration process. Some sharp objects, especially medical sharps waste, need to be stored in specific sharps boxes, and it is best to shred them before incineration.

3. The composting method can also be called the biological explanation method. It uses the microorganisms in nature to decompose the organic matter in the garbage to form fertilizer, which is used as the nutrition of crops, so as to achieve the purpose of processing the garbage and improving the productivity of the land. Heavy metals have the potential to contaminate soil.

Different garbage has different composition and calorific value. It must be sorted and collected in the early stage to improve the processing efficiency.
