What is Alternative Daily Cover (ADC)?

Alternative Daily Cover (ADC) is best understood as cover materials used to manage landfill operations in a way that minimizes odor, control vectors, and prevent wind-blown litter while also addressing environmental compliance. The correct choice highlights that ADC can be made from innovative materials, including spray slurries and tarps. These materials provide flexibility in landfill operations and can be beneficial in reducing the volume of soil needed for daily cover, which can lead to cost savings and increased efficiency in operations.

The use of spray slurries can also effectively seal the waste underneath, reducing emissions and leachate creation, while tarps provide a quick way to cover waste during operational hours. Thus, the focus on alternative materials like spray slurries and tarps supports enhanced operational practices in landfill management.

Other options refer to more traditional or specific methods of covering waste. The use of soil is a common method but not considered alternative and does not capture the broader essence of ADC. Similarly, focusing solely on vegetative waste is too restrictive, as ADC encompasses various materials beyond just organic matter. Heavy machinery is typically used in the covering process, but it does not represent what ADC itself is; ADC is about the materials used for cover rather than the equipment that applies it.
