Household garbage that cannot be recycled or is non-recyclable is transported by garbage trucks to the landfill, where it is inspected and then automatically weighed by a computer.
2. Landfill construction
Prior to this, the landfill is prepared in advance. Everything from the location of the landfill to the industrial design can be decided after careful consideration. The base and perimeter of the landfill are reinforced with an impermeable clay layer and an impermeable membrane is laid down so that the waste does not seep down. The membrane is so strong that it will remain intact for decades, so there is no need to worry about contamination of the soil and groundwater from the waste.
3. The waste is paved and compacted
After the waste is dumped into the landfill pit, the density of the waste will be greatly increased by repeated paving and compacting. The leachate produced by the garbage will be channeled by pipes to a special place for treatment.
4. Completion of Closure
After each landfill unit is completely filled, we cover it with a layer of soil and plant trees to blend in with the surrounding environment, and closely monitor the environmental impact of the landfill area over time.
5. Landfill gas collection
Inside the sealed landfill, organic waste begins to ferment due to the lack of oxygen, producing a large mixture of gases (methane, carbon dioxide, nitrogen, etc.). These gases are transferred to the power plant through vertical and horizontal gas wells crisscrossing the landfill.
6. Landfill Gas Power Generation
The gas is purified and supplied to an internal combustion engine through combustion. The internal combustion engine generates electricity, part of which is used for the plant's own consumption and part of which is transported to the national power grid. Waste heat from the combustion can also be transferred by heat exchangers to nearby district heating networks or industrial and agricultural facilities.
Of course, these rough steps do not present all the operational details of a landfill, such as strict control of the exposed surface of the waste, disinfection and deodorization of the plant and so on are all necessary aspects of the landfill. Sanitary landfill, but a technical job!
