What causes landfill pollution?

Can landfills cause pollution to the environment?

Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.

What are the effects of landfills on air pollution?

Elevation in odour thresholds from landfills are associated with an increase in landfill gases emission, and low wind speed which may hinder pollutants dispersion especially in complex terrains [10, 12]. Methane (CH4) and carbon dioxide (CO2) are among the major Greenhouse Gases (GHGs) emitted from landfills [13–16].
