The diagram illustrates the blueprint of a modern landfill for getting rid of household waste.
Overall, the process can be divided into 4 stages. These stages begin with the construction of the landfill and end with the closure of it.
At the beginning of the process, a giant hole is dug beneath the earth’s surface in a shape of a trapezoidal prism above a bed of natural rock. Then, a layer of clay is placed, followed by a cover of the synthetic substance on it to prevent the earth’s mantle from being penetrated into by the toxic waste material. At this point, a set of drainage pipes and drainage bank are also installed, going through two aforementioned layer in order to separate the sewage from the rubbish.
Once the landfill’s manufacture is finished, it is filled with household refuse. After being filtered out, the leachate will drift to the bottom and stagnate in the drainage tank, before being removed via the drainage pipes. Following the pulverization of waste into a mud-like compound, the top is sealed with a clay lid, with the funnelling of the gasses emitted from the site.
