Do I have that backwards?

Here's a pickup price for steer manure:
http://www.acmesand.com/compost/

That's $27 a yard. ~110 lbs/cu. ft. = 990 lbs per yard. = 0.45 tonne
So sixty smackers gets you a tonne of steer manure.
That should yield 25 m^3 of biogas which can be cleaned up to result
in 12.5 m^3 of methane.

I can pick up a yard of chopped grass off the street for
approximately $0 and earn the thanks of the homeowner
and city just about any week day.

That's $0 a yard. 74 lbs/cu. ft. = 667 lbs per yard. =.303 tonne
So zero smackers gets you a tonne of chopped grass.
That should yield 195 m^3 of biogas which can be cleaned up to result
in 97.5 m^3 of methane.

Recapping:

Steer manure: $4.80 per m^3 of methane.
Chopped grass: $0.00 per m^3 of methane.

Seems like chopped grass is less expensive.

The manure is all in one place. How many homes have a ton of grass
clippings by the street? The manure would be loaded with a front end
loader, taking a couple minutes. How long would it take you to load all
the grass clippings? Some towns have laws against picking you anything
left for their trucks. How many tickets do you want to pay?

If you only need a few cubic meters, you're likely correct -- often for small
quantities of goods the economics are backwards or at least seemingly
arbitrary (e.g., some folks running their cars off of biodiesel are able to
freely obtain grease from french fry fryers -- "free fuel").

But if you need to to produce thousands of cubic meters per day, every day...
the manure might easily start to look (if not smell :-) ) more attractive.

This is problem with a lot of alternative energy sources... many don't scale
well. With the so-called "smart grid" this purpotedly won't matter as much,
at least... but I think to date the smart grid has been about 95% hype.

Apparently someone is going around the rest stops attaching stickers to the
hand dryers in the restrooms that say:

I keep the chopped grass on my lawn. My guess is that yours is knee deep in
bullshit.
