Alternative Feed stocks...

What are some alternative feed stocks? I don't have a ready supply of most organics, but it seems nitrogen and carbon is what is needed:

Any organic material can be anaerobically digested including manure from any type of animal.
Chicken, cow and pig manures are commonly used for biogas because they have a good natural
C:N ratio. Collect the manure in a container and crush it so that there are no large chunks
(especially when using dry manure). Add water and mix together until it forms a thin slurry of a
consistency that can be poured into the digester (about 50% water, 50% manure). Depending on
ambient temperatures and slurry mixtures, you may need to wait seven to ten days for gas
production to begin.

So how about cardboard and urine? Seriously, I have plenty of both, and a constant supply of more. I am city bound, and apt to stay that way, and have honestly had a hard time getting any free organics other than autumn leaves. Any other ideas?

What use did you have in mind for the methane you produce? Cooking, fuel for a generator, heating for home and/or hot water?
What is your living situation? Apartment, house, motor home rv? What amount of land are you working with?
How much methane do you need to produce to meet whatever need you are trying cover?

Give a little more information so we can help, please.
