1. Methane (CH4): Methane is a potent greenhouse gas that contributes significantly to climate change. It is produced when organic materials, such as food scraps and paper, break down in the absence of oxygen.
2. Carbon dioxide (CO2): Carbon dioxide is another greenhouse gas that is produced in large quantities from the decomposition of organic matter.
3. Hydrogen sulfide (H2S): Hydrogen sulfide is a toxic gas with a strong rotten-egg odor. It is produced by the breakdown of sulfur-containing compounds, such as proteins.
4. Ammonia (NH3): Ammonia is a pungent gas that is produced by the decomposition of nitrogen-containing compounds, such as proteins.
5. Volatile organic compounds (VOCs): VOCs are a group of organic chemicals that are released as gases at room temperature. They can be produced from the breakdown of a wide range of organic materials, including solvents, paints, and cleaning products.
The composition and amount of gases released from a landfill can vary depending on several factors, such as the type of waste, the age of the landfill, and the environmental conditions.
