[Digestion] Digestion Digest, Vol 16, Issue 1

[mrcdb]

Hello All,

I am an Energy Consultant in Erie, MI,  USA

I have been researching anerobic digestion lately as related to Municipal 
Solid Waste (MSW) landfills and landfill gas to electric plants.

I am a member of the Solid Waste Association of North America (SWANA) and 
just completed their landfill gas ecourse.

Anyway, in their course they state that "a moisture content, of the 
digestion material, of 38-40% is ideal for the most methane production" and 
that "recirculating the leachate produces lots of gas"
They say that a moisture content much over 40% is a saturated condition, and 
will slow or stop methane production!

So, it seems to me, that a digester full of water is not an efficient way to 
produce methane?

Does anyone have any thoughts on this subject?

Thanks,
