The image illustrates the stages of constructing, using, and closing a modern landfill for household waste. During construction, a man-made hole is created in the natural rock, lined with synthetic lining and drainage pipes leading to a drainage tank, with a clay base. In the use phase, household waste is dumped into the lined hole, with an outlet for waste liquid at the base. In the closure phase, the landfill is sealed with a clay cover and sand, and a pipe extends from the waste area for gas release.
Given the complexity of the image, the above description may not be entirely accurate.

The process demonstrates how a modern landfill for household waste is mass-produced.
Looking at the picture, it is obvious that there are three main stages in the process, beginning with the construction, and ending with the closure.
To begin with, the construction has two different steps. Firstly, the giant hole is dug from the natural rocks. Then, it is accompanied by a thick layer of clay, and followed by a synthetic lining layer. In addition to this, there is a drainage pipe and a drainage tank systems are put in in order to remove the sewage.
The second step is usage, this waste is put in that man-made hole, and the waste liquid is also removed by that system. In the final step, the big hole is covered by clay, because there is a lot of waste. Therefore, the pipes are adopted to remove the toxic gasses.
