The process shows the design of a modern landfill for household waste.
Sample Response
The diagramflow chart illustrates the process by which a modern household waste landfill is constructed, used, and closedsequence of operations for the disposal of household waste in a modern landfill site, Overall, the process comprises three distinct phases: construction, use, and closure.which can be divided into three principal stages: site construction, waste deposition, and final site closure.
To begin with, a man-made holecavity is excavated within natural rock. This hole is then lined first with a layer of clay and subsequently with a synthetic liningmembrane. Underground drainage pipes, connected to a drainagecollection tank, are fitted within this lining system to capture waste liquid. Once the landfill structure has been completed, household waste is delivered to the site by lorrieswaste lorries and deposited inside the lined cavity.
In the final phase, the landfill is capped with a clay cover. A pipe is installed to permit gases generated by the buried rubbish to escape. Notably, the clay and synthetic layers beneath the waste prevent waste liquid from leaching into the surrounding rock while liquid drains into the tank belowact as a filtration system, separating clean water from contaminants.
