Landfill gas is a natural by-product of the decomposition of organic material in landfills. This gas consists of
AAlmost 50 percent methane as the primary component
BAlmost 50 percent carbon dioxide
CA small amount of non-methane organic compounds
DAll of the above ✓ Correct
Correct answer: (D) All of the above
Explanation
Landfill gas is roughly half methane, close to half carbon dioxide, with small amounts of non-methane organic compounds.
Methane near fifty percent is the primary combustible component formed by anaerobic decay.
Carbon dioxide near fifty percent is released alongside methane during decomposition.
Traces of non-methane organic compounds also appear in the gas mixture.
Methane makes the gas flammable and a potent greenhouse contributor.
Captured landfill gas can be flared or used to generate energy.
