Methane Emitted vs Annual Organic Waste
Fórmula
## 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.
Ejemplo Resuelto
100 tons of organic waste with 100 m3/ton methane yield and 50% collection.
- 01Total methane: 100 * 100 = 10,000 m3
- 02Emitted: 10,000 * 50% = 5,000 m3
- 03Emitted in tons: 5,000 * 0.000717 = 3.6 metric tons CH4
- 04CO2 equivalent: 3.6 * 28 = 100 metric tons CO2e
Preguntas Frecuentes
How much methane do landfills produce?
Landfills are the third-largest source of human-related methane in the US, producing about 15% of total methane emissions. Each ton of organic waste generates 50-150 m3 of methane over its lifetime.
Can landfill methane be captured?
Yes. Landfill gas collection systems capture 50-85% of methane. The gas can be flared (reducing climate impact) or used to generate electricity through landfill-gas-to-energy projects.
How does composting prevent methane?
Composting decomposes organic waste aerobically (with oxygen), producing CO2 instead of methane. Since methane is 28x more potent than CO2, composting drastically reduces the climate impact of organic waste.
