What are the two most common methods of sanitary landfill operation?

The two most common methods of sanitary landfill operation are the area method and the trench method.

In the area method, waste is spread out in thin layers, compacted, and then covered with soil or other materials to minimize odor and attract pests. This method allows for better compaction and management of the landfill area, promoting efficient use of space and reducing environmental impact over time.

The trench method involves excavating a trench into which the waste is placed. Once the trench is filled, it is covered with soil. This method is generally used for smaller landfills or in areas where land availability is limited.

Both methods focus on effective waste management, sanitation, and minimizing health risks associated with landfilling. They prioritize the safe containment of waste and the reduction of potential leachate and greenhouse gas emissions, which is crucial in protecting the environment and public health.
