[Digestion] Solar Heated Batch Bladder Digester for Poultry

[Paul Harris]

G'day Steven,

Yes, no methanogens = no methane! This is what happens in silage heaps on
farms. Cow manure has methanogens so becomes the inoculum, inoculum can also
come from another digester (but cows are often closer).

In your situation of periodic clean outs a batch system is more sensible, as
with plug flow you need to add raw material at least daily for reasonable
operation (and if you store the substrate it will still decompose and so you
lose methane potential anyway).

Hope this helps,
HOOROO

Thanks so much for responding. And pardon my ignorance, I'm trying to 
get my learning curve up as soon as I can!

Does a lack of methnogens mean that it cannot produce methane (surely 
not) ... or that in terms of an innoculum it can not produce that 
activated culture, and a cow manure, with some straw should be added to 
produce the innoculum?

Also what factors in this would differ with a batch load (our plan) as
opposed to a plug flow?

Thanks!
Steven
