Hi all!
Just some addotions to sugar and gas yields:
In theory (thanks to Dr David Fulford) 1 kg of sugar gives 865 litres
of biogas, so Dr Karves figures are ballpark.
The yield per kg may differ (in small amounts) what sugar
(Glucose/Saccharose/...) is used. But the gas yield differs a lot what
kind of normation is used. Under German standard gas conditions used in
the field of biogas ( 273.15K = 0°C; 1013.25 mbar, dry gas) sugar as
"Glucose" would result in 747 L/kg. You can easily check and recalculate
this for "norm gas conditions" in your country. Often 20°C is used
instead of 0°C, so the gas yield would be higher.
You can have a look at the buswell formula:

and the given table below. So often people have different figures but
are talking about the same thing.
Kind regards
