The provided diagram depicts the comprehensive process involved in the design of a modern landfill, aimed at accomodating household trash.
Overall, the intricate process comprise four pivotal stage, commencing with digging a hole and culminating in the degradation of waste and the release of gas.
Initiating with stage 1, an enormous hole is excavated by individuals, which is situated above a bed of natural rock. Afterwards, the hole is lined with a layer of clay, and then filled with a layer of synthetic substance to prevent toxic substance from leaching outside and harm surrounding soil. Following that, not only a drainage tank is installed just above the synthetic substance but also drainage pipes are set horizontally, alongside a pipe digging into the surrounding soil and attached with others pipes to consolidate them.
Once household waste is full, the waste liquid sinks into the bottom and is directed into the tank . Additionally, the waste is covered by a layer of clayer above it to prevent its bad smells emitting from the rubbish. Ultimately, the pipe facilitates the emission to charge when the waste decays.
