Not sure if this will help:

m^3 biogas production/ton

fat & grease = 961
bakery waste = 714
food scraps = 265
corn silage = 190
grass silage = 185
green clippings = 175
brewery waste = 120
chicken manure = 80
potato waste = 39
pig manure = 30
cow manure = 25

No idea how accurate the above is.

Maybe it's around the 190 to 170 range?
