Methane captured
75,00,000 m³ CH4
Total methane generated
1,00,00,000 m³ CH4
Recoverable energy
78,750 MWh
Uncaptured emissions
25,00,000 m³ CH4
Formula and working
CH4 = waste mass × generation rate; energy = CH4 × heating value × capture efficiency
- 1
Collect the inputs
Landfilled waste mass = 100,000 tons; Methane generation rate = 100 m³ CH4/ton; Gas capture efficiency = 75 %
- 2
Apply the formula
CH4 = waste mass × generation rate; energy = CH4 × heating value × capture efficiency
- 3
Result
Methane captured = 7,500,000 m³ CH4
