What is the trench method of landfill?

The trench method of landfill involves excavating trenches into which waste is placed and subsequently covered with soil. This approach is typically utilized in areas where the land is relatively flat, allowing for the efficient management of waste by utilizing the natural terrain. The covering of the waste with soil helps to reduce odor, prevent scavenging by animals, and minimize environmental contamination by controlling leachate.

In practice, this method can be particularly effective in small-scale operations or rural settings where more complex landfill designs may not be feasible. The fundamental principle involves burying the waste, which reduces exposure to the elements and can help isolate it from surrounding environments.

This method differs significantly from others, such as those aimed at hazardous waste disposal, managing liquid waste, or incineration, which involve distinct techniques and regulations tailored to those specific types of waste management.
