The project with the capacity of 1000m³/d is to sort the landfill waste. The main purpose of this project is to screen out most of the combustibles, construction waste (bricks, tiles, ceramics, etc.) and humus from Landfill waste (mineralized waste). The humus is used for landscaping or mine restoration, construction waste is backfilled in situ, and combustibles are transported to incineration power plants for incineration. In this way, the landfill can be reused.
Landfill waste comes from MSW. With natural biodegradation of organic matter, landfill waste in anaerobic environment will produce toxic flammable gas such as hydrogen sulfide, and methane. Illegal landfill that without seepage prevention also has risk of contaminating soil and polluting groundwater problems.
