What is the area method of landfill primarily used for?

The area method of landfill, primarily used on the side of a hill or slope, is designed to take advantage of the natural topography to manage waste effectively. This method allows for the construction of a landfill that aligns with the slope, helping to maximize the landfill space while reducing the risk of soil erosion and leachate migration. Utilizing a sloped area can enhance drainage and stabilization, thereby ensuring the containment of waste materials and the management of environmental impact.

Flat areas may not be as effective for landfill development since they might require more extensive grading and drainage systems to manage water runoff. Urban centers present particular challenges, such as land availability and proximity to populations, while hazardous waste sites have more specific regulatory and design requirements that differ from those of general landfills. The area method is more suited to zoning strategies that consider natural land contours, making the side of a hill or slope the optimal choice for its efficiency and environmental management.
