The diagram illustrates the design and operation of a modern landfill for household waste.
Overall, it can be seen that the process has three main steps from contruction, usage and closure step to protect the environment.
In the first step, a man-made hole is excavated into natural rocks base. This hole is surround by a layer of clay and synthetic lining as a barrier to prevent comtamination. Moreover, drainage pipes and drainage tank are equipped into this hole to keep liquid waste from waste decompostion.
In the next step, the household waste is poured down from containers into the hole. This waste is compressed throughout a period and the liquid waste produced from household waste is kept in the drainage system to proctect the environment.
In the closure step, a thick layer of clay is coverd on the top of the landfill to prevent any further liquid waste prodution. Furthermore, gas pipes are installed to enable gases going out the outside.
