Methane, which is mostly generated out of solid waste, is one of the major greenhouse gases contributing to global warming. If methane from solid waste is utilised as a source of energy and fuel, it can become an effective alternative resource.
Methane contributes approximately 20 per cent to the annual increase in global warming. And landfills and sewers contribute to approximately 15 per cent of global methane emissions (West et al., 1998). If methane is allowed to leak into the atmosphere before being used, it effectively traps the sun’s heat and contributes to global warming. In fact, methane traps 20 times more heat in the atmosphere than carbon dioxide (CO2) and there is enough empirical evidence to prove that methane is...
