The diagram illustrates the design and process of a modern landfill system for disposing of household waste .
Overall, the process consists of three main stages: the construction of the landfill, its use for storing waste, and finally, its closure after reaching full capacity.
In the first stage, a large hole is dug into a natural rock base. The interior of the hole is then lined with a layer of clay followed by a synthetic liner to prevent waste form leaking into the surrounding ground. A drainage system is installed including pipes and a drainage tank, to collect and store any liquid waste (leachate), thereby reducing environmental contamination.
During the next stage, the landfill is used for waste disposal. Household waste is transported by trucks and deposited into the prepared landfill pit until it reaches its maximum capacity.
In the final stage, one the landfill is full, it is sealed off with a layer of clay. Additionally, a pipe is installed to safety extract gases produced form the waste decomposition.
