What is the function of daily cover in a landfill?

Daily cover in a landfill serves multiple important functions. It plays a critical role in controlling odors emitted from the waste, which is essential for maintaining good neighbor relations and minimizing complaints from the surrounding community. By covering the waste, the release of unpleasant smells is significantly reduced.

Additionally, daily cover helps in reducing the presence of flies and other pests that can thrive on exposed waste. By providing a physical barrier, it makes the environment less attractive to these insects, which can pose health risks and nuisance issues.

Fire risks are another concern in landfills, particularly with organic waste that can spontaneously combust or become ignited. Covering the waste with soil or other materials helps to minimize oxygen availability and provide a protective layer, thereby reducing the likelihood of fires.

Therefore, the function of daily cover encompasses all these aspects—controlling odors, reducing flies, and minimizing fire risks—making "all of the above" the most comprehensive and accurate answer.
