Perhaps you are right and I missed the part where an animal waste methane digester was placed inside the compost pile. What I have taken away from readings of accounts of Pain's work is that he was producing methane without the use of animal waste; that the methane was derived entirely from the "forest thicket compost" itself. If anyone can refute that methane is absolutely not obtainable from wood products as the base source of the methane, (and not merely for the heating of animal wastes) this would put the issue to rest. I must say that I would be disappointed if this were the case, but it would advance the discussion about retrieving accounts of Pain's accomplishments for the English speaking community.

My reading of the November 2000 Permaculture Activist article
explicitly said that Pain did not focus on detailing how he extracted methane
from the compost.
Based on the accounts I have read, the methane is not derived from the
compost, but rather a methane digester was imbedded in the pile to take
advantage of compost heat to maximize the rate of methanogenesis. The
primary function of the pile was production of heat (for hot water) and
organic matter for farming, with enhancement of methane production as a
>Nor have I seen any explanation of this elsewhere.
Methane digestion technology is widely distributed. Google "methane
digester small-scale" or other such combination; for example:
