Answer;
-Sanitary landfill
Sanitary landfill is a landfill with a plastic or clay liner that prevents the leaking of waste into soil and groundwater.
Explanation;
-Sanitary landfills are sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically.
-Sanitary landfills work by layering waste and soil in a large hole in the ground that is lined with plastic and clay. The waste is allowed to decompose and the linings help prevent contamination. When landfills are full, they are often capped and transformed into parks or natural areas.
