Extract methane from manure

Hi
I heard that it was possibel to extract methane from manure, so you could produce energy/power. I understand that ATZ and TVA (some german companies?) are making this, but im wondering how the process works.
Anyone who can tell me?

Re: Biofuel

You use methanogenic bacteria[/URL].
Which come free with the manure - especially if you have cows.
 
Re: Biofuel

It's not an extraction from manure - it's fermentation of manure with methane production.
