What is the main purpose of a geocomposite?

The main purpose of a geocomposite is to allow rapid transmission of leachate. Geocomposites are engineered materials often used in landfill applications to manage leachate, the liquid that drains or leaches from a landfill. By facilitating the quick movement of this liquid through the landfill system, geocomposites help ensure that leachate can be efficiently collected and treated, thereby minimizing the risk of contamination of surrounding soil and groundwater.

In addition to their primary function of managing leachate, geocomposites may also incorporate drainage materials, which further enhance their effectiveness in directing leachate flow. This rapid transmission is crucial for leachate management systems that require timely responses to avoid potential environmental hazards.

While preventing leachate from escaping is an important part of landfill design, geocomposites specifically focus on the controlled movement of leachate rather than outright prevention of its presence. Similarly, while accumulating leachate and providing cushioning for waste deposition are relevant functions within landfill operations, these do not capture the primary role of geocomposites, which is centered on the management and rapid flow of leachate.
