Definition

Noun:
- A waste disposal site where refuse is buried between layers of earth: A "sanitary landfill" is a specifically engineered area of land or an excavated site designed for the controlled, systematic burial of solid waste. It involves daily covering of waste with soil or other materials to control odor, pests, and environmental contamination.

Usage

The term "sanitary landfill" is used to describe modern, regulated waste management facilities, distinguishing them from open dumps. It is a formal, technical term common in environmental science, engineering, and public policy contexts.
Example: "The city council approved the construction of a new sanitary landfill to replace the old dumping ground."
Example: "Properly managed sanitary landfills include systems to collect leachate and methane gas."

Advanced Usage

"Municipal sanitary landfill": A landfill that accepts residential and commercial waste from a specific municipality or region.
- The county's municipal sanitary landfill is nearing its capacity.
The concept is central to discussions on waste hierarchy (reduce, reuse, recycle, recover, landfill) and landfill mining.
