Exploring the potential of biofiltration for mitigating harmful gaseous emissions from small or old landfills: a review.

Landfills are widely employed as the primary means of solid waste disposal. However, this practice generates landfill gas (LFG) which contains methane (CH), a potent greenhouse gas, as well as various volatile organic compounds and volatile inorganic compounds. These emissions from landfills contribute to approximately 25% of the total atmospheric CH, indicating the imperative need to valorize or treat LFG prior to its release into the atmosphere.
