[Stoves] papaya as feedstock for biogas

[adkarve]

Dear Peter,
you wanted to know if overipe papaya could be used as a source of methane.  Please remember, that if you are going to use only fruit pulp as the feedstock, and no dung, restrict yourself to only 1 kg dry weight of fruit pulp to 1 cubic meter of the digester capacity. Assuming about 80% water in papaya, the maximum amount of pulp that you can feed into the biogas plant would be 5 kg per cubic meter of digester capacity. You would get about one cubic meter of biogas from this much papaya pulp. 
Yours
