What happens when landfills get full?
When the landfill has reached its capacity, the waste is covered with clay and another plastic shield. … Landfills are not designed to break down waste, only to store it, according to the NSWMA. But garbage in a landfill does decompose, albeit slowly and in a sealed, oxygen-free environment.

Why are landfills environmentally harmful?
High levels of methane gas and CO2 are generated by the rotting rubbish in the ground. These are greenhouse gases, which contribute greatly to the process of global warming. Toxic substances end up in landfills, which leech into the earth and groundwater over time. This creates a huge environmental hazard.
How long does it take landfills to decompose?
