A landfill is a technical waste disposal facility, by deposition and confinement, which involves the occupation of a physical space in which waste is received in a controlled manner.

The techniques used in the construction and operation of landfills, and the requirements for monitoring and control, derive from the received waste characteristics, but also from the geological, hydrogeological and geotechnical profile of the land where they are built.

The protection of soil, surface water and groundwater, control of gases and treatment of landfill leachate are some of the aspects to consider in the design of a landfill, in order to safeguard the environment, which requires appropriate evaluation and design of infrastructure.
