[Digestion] gasyield indigenious cowdung

[Anand Karve]

Dear Gasan,
thanks for the information. Back in 1983, I spent about 6 months
in Freiburg, Germany, conducting my own research in plant physiology, At
that time I was not particularly interested in biogas technology, but I used
to attend a number of the guest lectures which the university offered.
I remember hearing a lecture in which the lecturer said that a biogas plant
was capable of digesting any organic substance, even petroleum. All one had
to do was to give it enough time. He then told us how the system developed
by him was being used by a paper factory in Germany to obtain biogas
from lignin, which remained behind after the cellulose in the wood was
extracted for making paper. I do not remember the name of the lecturer. .
Yours
A.D.Karve
