[Stoves] Values for methane production

[frank]

Stovers,

Are there conversion values for the different constituents of a biomass 
for expected methane production??

For example: I am running a proximate analysis on a waste strean so 
someone can determine if it would be worthwhile to make methane from it. 
The results are as follows as percent dry weight:

Fats, waxes and oils (4%)
resins (2.3%)
water soluble polysaccharides (5.7%)
hemicellulose (7.9%)
cellulose (2.8%)
protein (0.5%)
lignin-humus (43.4%)
ash (11.0%)
other components (22.4%)

A lot of the 'other components' are plastics and calculated as 100% 
substracted from the total analyzed added up. In this sample it is high. 
Most are around 4% undetermined.

Are there any calculations that can be made from the above to determine 
the expected amount of methane that will be produced from a typical system??


Thanks
Frank
