[Digestion] How to calculate biogas yield from dedicated energy crops?

[Paul Harris]

G'day Lou and All,

If you know the Volatile Solids content you can estimate the methane
production using the guides that each kg of VS destroyed gives 0.5 cubic
metres of methane and you will get about 70% VS reduction in a digester.

happy digesting,
HOOROO
