Where does methane come from?
Where does methane come from?
Having eaten a couple of meals with baked beans in over the weekend, my poor husband has tummy ache and of course wind.
I am led to believe that 'wind' is a large part of the global warming problem, but where does the methane come from? Maybe it's in the beans? but...
cows, for instance, only eat grass, and then produce methane,
Is it in the grass?
Please keep it clean I don't want to have my knuckles rapped.

Re: Where does methane come from?
It's a byproduct of digestion. Our systems
break down food into smaller components.
Some of these are useful to us (vitamins,
water, protein, etc.) and these are sent
to our cells. Some are not (insoluble fiber,
methane, etc.) and these are excreted.
I don't know about people, but in cows
the methane is produced by the bacteria
in the cow's stomach that help with the
cow's digestion.

Re: Where does methane come from?
If we could just get rid of all the termites and wetlands than methane production could be greatly reduced. That's why Monsanto should be given license to run the world. Benjamin Franklin's "notorious" essay to the Royal Academy on Farting Proudly is worth a read. Some said it was "scarcely worth a f*rt-hing."
Re: Where does methane come from?
The exact details of the process are still being studied, and more information may allow scientists to reduce cows' methane output.
I, and obviously the scientists, don't know exactly where the methane comes from. It can't just be magic'd into existence. Alchemy or what?

I believe an adequate answer was put forward. Here's something from the USEPA,Pammy wrote:The exact details of the process are still being studied, and more information may allow scientists to reduce cows' methane output.

Methane (CH4) is emitted from a variety of both human-related (anthropogenic) and natural sources. Human-related activities include fossil fuel production, animal husbandry (enteric fermentation in livestock and manure management), rice cultivation, biomass burning, and waste management. These activities release significant quantities of methane to the atmosphere. It is estimated that more than 60 percent of global methane emissions are related to human-related activities (IPCC, 2007:a ). Natural sources of methane include wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, and other sources such as wildfires.

These activities release significant quantities of methane
Yes but from where?
Take the cow thing as their diet is pretty straightforward.
The cow is born - does it contain methane? It eats grass - does that contain methane? It uses bacteria to break down the grass - does the bacteria contain methane?
Does the cow absorb methane through it's skin?
Where does so much methane come from? It can't just appear, it must be mixed with something somewhere and then released by "these activities"

Re: Where does methane come from?
In cows it is a by product of digestion just like your own Farts. My very own ancient puppy is resting on my feet as I write this, every few seconds I hear a toot. I'm lucky I'm conscious.Pammy wrote:These activities release significant quantities of methane

Re: Where does methane come from?
Cows use gastrointestinal bacteria to digest the otherwise indigestible cellulose of their plant food cell walls. This particular process yields methane. We eat plants too, but humans don't digest the cellulose cell walls-- we only get nutritive value from the plant materials released by chewing.
Now in the case of beans and some other vegetables, our methane comes from the breakdown of certain compounds called oligosaccharides. These are short chains of simple sugars such as fructose. We can only partially digest oligosaccharides, and the undigested portions serve as food for our gastrointestinal flora and one product of this process is methane.

In other words, methane is bacteria poo.

Well some of that poo is eaten by other bacteria that produce poo that in turn is eaten by other bacteria that produce poo that in turn..... The English have used poo gas for street lighting like since forever.Nanohedron wrote:In other words, methane is bacteria poo.

It's rather disconcerting to realise I'm a toilet.
