Methane is a chemical compound with the chemical formula CH 4. It is the simplest alkane and the main component of natural gas. The relative abundance of methane makes it an attractive fuel. However, because it is a gas at normal conditions, methane is difficult to transport from its source. Methane is a potent greenhouse gas, more potent than carbon dioxide unit per unit. The concentration of methane in the Earth's atmosphere in 1998, expressed as a mole fraction, was 1745 nmol/mol, up from 700 nmol/mol in 1750. By 2008, however, global methane levels, which had stayed mostly flat since 1998, had risen to 1800 nmol/mol.

The simplest saturated hydrocarbon. It is a colorless, flammable gas, slightly soluble in water. It is one of the chief constituents of natural gas and is formed in the decomposition of organic matter. (Grant & Hackh's Chemical Dictionary, 5th ed)
Is a chemical compound.
In its natural state, methane is found both below ground and under the sea floor, where it often finds its way to the surface and the atmosphere where it is known as atmospheric methane, it is the main component of natural gas.

We’re really not in a position from these data to say one way or the other what the origin of the methane is, because we are seeing signals here it’s worth coming back and doing more work.
The fact that she pointed out these structures is a great contribution to the field, along with the recent reports of methane and organics on Mars, her findings add an intriguing piece to the puzzle of a possible history for life on our neighboring planet.
You can treat it as normal waste (or) can use technology to produce methane. Once you capture methane, you reduce emissions released into the air, at the same time you still have the extra bio gas which you can use for vehicles, heating systems or power generation.
