[Gasification] Tom Reed Recovering from Fall

[Anand Karve]

Dear Tom,
you, the father of the TLUD technology, should not really worry about the
dirtiness of buning lignin. Cellulose can be easily converted into methane
in an anaerobic digester. There exist biogas digesters that accept green
leaves as feedstock. They yield, on dry weight basis, about half as much
biogas as starch. This is because the midribs and veins of leaves are made
of lignin. Constituting about half of the dry weight of a leaf, the midribs
and veins are indigestible. The undigested debris from the biogas plant can
be easily pelletted, even with bare hands. Getting energy in the form of
methane out of raw biomass first, and then using the non-digestible part as
solid fuel, in the form of pettets, could be a more rational way of using
biomass as fuel.
Get well soon.
Yours
A.D.Karve
