Landfill Methane Calculator — Formula
## 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.

Exemplo Resolvido
100 tons of organic waste with 100 m3/ton methane yield and 50% collection.
- Total methane: 100 * 100 = 10,000 m3
- Emitted: 10,000 * 50% = 5,000 m3
- Emitted in tons: 5,000 * 0.000717 = 3.6 metric tons CH4
- CO2 equivalent: 3.6 * 28 = 100 metric tons CO2e
