How to Calculate Landfill Methane Emissions

Organic waste in landfills decomposes anaerobically, producing methane.

Formula

Methane Generated = Waste (tons) * Yield (m3/ton)

Methane Emitted = Generated * (1 - Collection %)

CO2e = Methane * 28 (GWP-100)

The density of methane is approximately 0.000717 metric tons per m3 at standard conditions.

计算示例

100 tons of organic waste with 100 m3/ton methane yield and 50% collection.

  1. Total methane: 100 * 100 = 10,000 m3
  2. Emitted: 10,000 * 50% = 5,000 m3
  3. Emitted in tons: 5,000 * 0.000717 = 3.6 metric tons CH4
  4. CO2 equivalent: 3.6 * 28 = 100 metric tons CO2e
