[Stoves] Values for methane production

[Bruno M.]

Hi Frank,

You didn't told us how you want to convert this woody stuff to CH4.
If by anaerobic digestion, the digester list might be a better place to ask.
digestion at listserv.repp.org

Or if you like to gasify it, the Gasification list:
gasification at listserv.repp.org
