The provided image depicts how domestic waste is treated in a contemporary landfill.
Overall, it is readily apparent that the process involves three main stages, namely construction, waste filling, and closure.
In the initial step, a hole is dug in the ground, forming a horizontal rectangle. The bottom of this hole is positioned full of natural rock. Once the hole is made, a drainage tank is placed at the bottom. In the subsequent step, a layer of clay and a synthetic lining are added to cover the surface of the storage area. Finally, a system of five drainage pipes is installed at the bottom of the area.
Shifting our focus to the landfill’s operation and closure, trucks first transport domestic rubbish to dump into the previously installed tank. Once the landfill reaches full capacity, another system of pipe is used to release underground gasses, while the clay is spreaded to fully cover the surface.
