That
is very cool. I have seen this process somewhere. H2SO4, that is
Sulphuric Acid
right? I have a friend with a small sawmill and a 2000 gallon tank
sitting
idle, he is going to use it for rainwater collection. I asked him if he
ever
fermented sawdust. He said, ”It composts pretty well when we get a
little rain.”
He was keen on the idea of trying, but shied away from the idea of
putting Sulphuric
acid in the tank to shock the glucose. I told him we would wash it out
real
quick, LOL.
So yeah I am hoping that another way to break
down the cellulose has been
developed. I have heard of enzymes and mushroom spoor but nothing very
miraculous
yet, Hoping… rather naively I’m afraid.

P.S.
What type of wood did you use?
I understand it makes a difference.
We have
mainly Ponderosa Pine Trees.

I did this in the 80s as an one-time expt. Boiled sawdust in 30%
H2SO4 for 3h, neutralised with lime, filtered and fermented the sugar
with yeast into alcohol which was recovered by distillation. Reckon
sawdust/biomass waste can be obtained at v.low cost. Cost of H2SO4 can
be offset by value of CaSO4,gypsum, which is a saleable commodity. Yet
no takers anywhere currently, despite rising petrol prices. Sad really
because we are inhibited society really.

I
am new here, but this certainly looks like the place to be.
I my opinion looking at ethanol strictly from a BTU to create over BTU
available leaves out too many important variables. Even if with
Ethanol’s numbers looking dismally uneconomical to many people who I
will call naysayers the clincher for me is ethanol comes from a
renewable resource corn. If we can figure out a way to break down the
cellulose in wood waste forests products we would really have
something. Don’t get me wrong I want to help the American farmers but I
live in the forests of the South-West USA and we have a real problem
with small diameter trees choking the forests and creating a fire
hazard. The solution becomes, two birds with one stone, economically
speaking. The trees have to be removed and are anyway but they are
being chipped and left in most places. Lets do some real research on
fomenting wood fibers.
