What is the biggest environmental threat from landfill sites?
Greenhouse gas production
Greenhouse gas production is perhaps the biggest environmental threat posed by landfills. When organic material such as food scraps and green waste is put in landfill, it is generally compacted down and covered. This removes the oxygen and causes it to break down in an anaerobic process.
What are the pros and cons of landfills?

What is landfill pollution?
Landfills can cause air pollution by emitting dust and gases such as methane, carbon dioxide, and etc. These gasses are produced as a result of the decay of organic wastes by microorganisms [15].
What are the disadvantages of landfills?

- Landfills are Partially Responsible For Climate Change. One tonne of biodegradable waste can produce about 400–500 cubic meters of landfill gas.
- Methane Lights up Easily.
- Contaminate Soil and Water.
- Landfills Affect Wildlife.
- Accidents Can Happen.

How do landfills damage the environment?
As landfill sites are filled, some local species can be replaced by other animals that feed on refuse, like rats and crows. Leachate is the liquid produced in landfill sites. This can become toxic and thus contaminate nearby streams, ponds and lakes, damaging the habitat of many different organisms.
What are the most common problems with landfills?
Problem #3: Greenhouse Gas. Organic materials such as food scraps and yard waste are usually compacted when they are put into a landfill. The problem is that this removes oxygen and causes the material to break down anaerobically.
What are the most common toxic materials found in landfills?
Mercury is another toxic substance that frequently appears in landfills. It comes from fluorescent light bulbs and poses major health risks. Inhaling even a small amount of mercury vapor can harm our kidneys and cause respiratory failure.
What happens to waste that is buried in a landfill?
Aside from the financial impacts, waste that is buried in a landfill will break down slowly and present problems for future generations. There are several well-established techniques available to reliably and consistently treat landfill wastes. Brian Bausback is the Manager of technical services for Handex.
What causes leachate in landfills?
Rain falling on the top of the landfill is the greatest contributor of leachate. In other cases, groundwater entering the landfill can produce leachate as well. As liquid seeps through the landfill and collects decomposed waste components, chemical reactions take place and produce a toxic leachate “cocktail.”
