The diagram illustrates how a modern landfill is built for household waste and the way that a landfill operates.
Overall, a modern landfill is constructed through various straightforward steps and is utilized for dividing household waste into different types and decomposing them.
As depicted in the diagram, in the form of initial natural rock, a rectangular man-made hole is created in the middle of the rock. Then, a synthenic lining is built on this hole, with a clay layer under the synthenic lining. Additionally, several drainage pipes are put in the bottom of the hole and a drainage tank is also erected in the right bottom of the hole simultaneously.
Regarding its operation mechanism, the containers which contain household waste pour rubbish into the landfill from both sides of the landfill. Next, the drainage pipes play a role in dividing household waste into normal rubbish and waste liquid, waste liquid then is stored in the drainage tank.
After dividing household waste, all of the amount of rubbish undergoes closure process. A long pipe is affixed to one of the drainage pipes, ensuring that waste gases escape through this pipe. Remaining waste are stored on the man-made hole which is sealed by a clay layer in the top of the hole.
