Even so, while cardboard definitely counts as green packaging, it has environmental drawbacks. When it’s dumped into landfill sites, its biodegradation emits methane gas, creating a substantial carbon footprint. Moreover, it’s made of tree fibres, so it adds to the ris...

In nature, methane is available, abundantly. In a biological system, methane gas is produced in marshy/swampy lands by anaerobic bacterial decomposition of vegetables and biological wastes. Therefore, wetlands are major sources of production of methane. Because of this source of the produce of metha...
According to the latest research, there are three mainsources of methane emissions. Firstly, methane is released during the extraction of raw fossil fuels, particularly during the mining of coal. Secondly, the gas is being produced by the decomposition biodegradable waste in landfill...
Methane is produced naturally through decomposition. But again, human activity has displaced the natural balance. Large amounts of methane are released by cattle farming, landfill waste dumps, rice farming and the traditional production of oil and gas. ...
On the energy market, everything is decided and controlled by the price of a barrel of oil. During periods when the cost of petroleum remains high, it becomes worthwhile to develop unconventional natural gas resources and to focus on sustainable and renewable sources of energy such as wind, so...
Beyond water and CO2, the other important “natural” greenhouse gases are : methane (CH4), which is nothing else than the cooking gas we use in our stoves, Nitous oxyde (N2O), the scholarly name for….. laughing gas (which is not so much amusing here), ozone (O3), which molecul...
The captured methane also can be piped to nearby industrial customers or compressed to make compressed natural gas or cooled to make liquefied natural gas to power vehicles, as Waste Management, one of the two primary landfill companies in the United States, did for some of its garbage trucks ...
re going to need as a future society. So, we need more research, such as looking at how we remove methane from the atmosphere. All of the approaches we’ve described don’t deal with that. It may well transpire that some of the things that are d...
