sci.landfill-gas-LFG-generation Calculator
Calculates landfill gas generation rate from waste mass, methane yield potential L₀, and first-order decay rate k using the EPA LandGEM model. Methane generation peaks 3–5 years after waste placement — typical L₀ = 170 m³/Mg for municipal solid waste in temperate climates.
Inputs
Waste Mass T

K Decay Per Yr
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
T Yr
Reference formula or conversion factor shown for context.
Results
LFG generation rate (m³/yr)
The proportional relationship between two quantities.
methane generation (m³/yr)
The proportional relationship between two quantities.
