What can go wrong with landfills?
Along with methane, landfills also produce carbon dioxide and water vapor, and trace amounts of oxygen, nitrogen, hydrogen, and non methane organic compounds. … This can result in leachate, a liquid produced by landfill sites, contaminating nearby water sources, further damaging ecosystems.
What happens if a landfill catches fire?
Landfill fires are especially dangerous as they can emit dangerous fumes from the combustion of the wide range of materials contained within the landfill. Key parameters of concern are carbon monoxide, hydrogen sulphide, volatile organics. Production of dioxins and furans is also a documented risk factor.
How do landfills catch fire?
Decomposition of organic garbage produces combustible methane gas, which often catches fire. Since the source of the fire is buried tens of meters deep inside the mound and the slopes are almost vertical, the flames become much more difficult to put out.
