My methane note book. The blue one with all the post-its (SMILE)

I got it from:
"Key Elements of Biogas Energy Systems Anaerobic Digesters" By Brian Gannon,
Biogas Energy Systems www.biogas-energy.com
I think they use a two stage reactor but I could be wrong.

It's been too long but isn't the rule of thumb that you convert about 1/2 of
the carbon in your feedstock?

Too bad that Mr. Bates is not here to show us the way.

I tried a 55-gallon drum of switchgrass and did not have any luck, long
 story. It made about two liters of CO2.
