Sampling method for the determination of methane emissions from landfill surfaces

Area of Science:

• Environmental Science
• Atmospheric Chemistry
• Geotechnical Engineering

Background:

• Standardized methods for measuring landfill gas (LFG) emissions from landfill surfaces are currently lacking.
• Accurate LFG emission data is crucial for effective landfill management and pollution control.

Purpose of the Study:

• To develop and validate a reliable sampling method for quantifying landfill gas emissions.
• To investigate the relationship between landfill gas emissions and meteorological factors.

Main Methods:

• Development of a static hood sampling system, including theoretical design and fluid-dynamics simulations.
• Experimental validation of the sampling method and optimal procedure definition.
• Literature review and experimental data collection to identify key meteorological parameters influencing LFG emissions.

Main Results:

• A static hood sampling method was successfully defined and validated.
• Atmospheric pressure and soil humidity were identified as the primary meteorological factors affecting LFG emissions.

Conclusions:

• The developed static hood method provides a standardized approach for LFG emission measurement.
• Understanding the influence of atmospheric pressure and soil humidity enables better landfill management and emission control strategies.
