What do landfills consist of?
Bacteria in the landfill break down the trash in the absence of oxygen (anaerobic) because the landfill is airtight. A byproduct of this anaerobic breakdown is landfill gas, which contains approximately 50 percent methane and 50 percent carbon dioxide with small amounts of nitrogen and oxygen.

Besides, what is in a landfill?
A landfill is a carefully designed structure built into or on top of the ground, in which trash is separated from the area around it. Why are landfills important? Landfills contain garbage and serve to prevent contamination between the waste and the surrounding environment, especially groundwater.

To put it simply, sanitary landfills operate by layering waste in a large hole. The deepest spots can be up to 500 feet into the ground, like Puente Hills, where a third of Los Angeles County's garbage is sent. As materials decompose, landfill gas experts continuously monitor groundwater to detect any leakage.How are landfills bad?
Landfills get a bad rap — but with modern landfills, it's not so much the landfill itself that's bad, as it is the amount of stuff in landfills that's bad. Plus, as all that stuff in landfills decomposes, it creates methane, a very powerful greenhouse gas that contributes to climate change.What is a cell in a landfill?
