What characterizes the area method in landfill construction?

The area method in landfill construction is characterized by the placement of refuse on slopes and covering it with soil. This method allows for efficient use of the available land area, as it enables the landfill to be built up in layers or cells. By placing refuse on a slope, the area can accommodate greater volumes of waste while allowing for effective drainage and compaction. The soil cover plays a crucial role in minimizing odor, pests, and other environmental impacts associated with waste decomposition.

Additionally, this method is advantageous for managing the stability of the landfill, as it can prevent potential landslides and offer better control over leachate and gas emissions. The layering technique employed in the area method also aids in monitoring the waste over time, as operational space is maximized without extensive excavation or alteration to the natural land surface.

In contrast to the area method, other approaches may focus on different styles of construction and waste management, such as the trench method, which involves compacting refuse in deep trenches rather than layering it on a slope. Each method has particular applications and suitability based on the type of waste and the geographic landscape where the landfill is constructed.
