The given diagram illustrates the blueprint of a modern landfill designed for the disposal of household waste.
Overall, the process involves three main stages: construction, usage, and closure.
Initially, a large hole is dug above a natural rock foundation. Once the hole has been excavated, it is lined with a thick layer of clay, followed by a layer of synthetic material on top of the clay. Additionally, drainage pipes and a drainage tank are installed at the bottom to remove toxic liquids from the landfill.
During the usage stage, the landfill is filled with household waste. As the waste decomposes, liquid waste accumulates in the drainage tank, which is then pumped out through the drainage pipes, thereby minimizing the buildup of gasses.
Finally, once the landfill reaches its capacity, it is sealed with a clay lid. Over time, as the waste decomposes, gasses are generated and released through the installed pipes, ensuring safe gas emissions from the landfill.
