The diagram illustrates the processes of a modern landfill for household waste.
The first phase concentrates on construction. A man-made hole is excavated in a piece of Natural rock. Then, there two different layers are installed in the hole, including an inner layer is paved by the clay and an outer layer laid by the Synthetic lining. Next, a small drainage thank is dug in the bottom-right of the hole, and drainage pipes are laid along the bottom of the hole to collect liquid waste.
In the ‘use’ phase, household waste is transported by trucks, this waste is dumped and deposited into the artificial hole. Then, waste liquid is expelled through the drainage pipes into the drainage tank. In the final phase, which is the closure stage, this waste is sealed by the clay cover to prevent further contamination. Finally, Gases generated from decomposing waste are emitted through a pipe.
Overall, it takes four main phases to build and use a modern landfill for household waste. The main purpose may be to accelerate the dissolution process of waste.
