landfill cover systems

Landfill cover systems are layers placed over a waste landfill to contain the trash, prevent odors, and protect the environment. They typically include a barrier layer, such as clay or synthetic material, to prevent leachate (liquid from waste) from seeping into the ground. A soil or soil-like layer is then added for stability and ease of access. Vegetation may grow on top to reduce erosion and improve appearance. These covers also help control pests and reduce emissions of greenhouse gases like methane. Overall, landfill covers ensure safe, long-term containment and minimize environmental impact.
