What is a landfill and how does it work?
Landfill – carefully designed structure built into or on top of the ground in which trash is isolated from the surrounding environment (groundwater, air, rain). This isolation is accomplished with a bottom liner and daily covering of soil. A sanitary landfill uses a clay liner to isolate the trash from the environment.
What is landfill Short answer?
A landfill is a place where waste is kept. Once the waste is crushed into very small pieces, it is buried, but without oxygen, a dangerous gas called methane is created. This process is called anaerobic digestion. In some countries, the methane from landfills is used to generate energy.
