STATISTICS

▫️ In landfill sites, the types of waste emit GHGs in the following pattern.

▫️ Of all the GHGs emitted here, methane is the most abundantly released gas.

▫️ The CH₄ and CO₂ together form more than 37 metric tons of GHGs every year.

SOLUTIONS

▫️ A basic approach to reducing CH₄ from landfills is to reduce the bulks of waste produced.

▫️ Besides that, biosolids can be used to make a topsoil layer to cover landfill sites that are no longer in use. The microorganisms in the biosolids can convert CH₄ to CO₂. (Although CO₂ is also a GHG, it is less potent than CH₄.)

▫️ Additionally, landfill gases can be burned to produce energy as it will be a good renewable energy source.
