What is the key advantage of using a geomembrane as an Alternative Daily Cover (ADC)?

The key advantage of using a geomembrane as an Alternative Daily Cover (ADC) is the significant increase in airspace capacity within the landfill. Compared to traditional soil cover, a geomembrane ADC is much thinner, typically a few millimeters thick. This thin profile results in a substantial reduction in the amount of airspace consumed by the daily cover material. This saved airspace translates directly into increased landfill lifespan and revenue generation, as more waste can be disposed of in the same volume. Furthermore, geomembrane ADCs can offer enhanced odor control, reduce vector attraction (e.g., birds and rodents), and minimize water infiltration compared to soil covers. While soil covers typically require 6 inches or more of material each day, a geomembrane ADC provides the required performance characteristics with minimal airspace loss, extending the operational life and profitability of the landfill.
