[Gasification] Creosote as Binder???

[Tom Miles]

You're better off to make gas and not make creosote.

These days pellets are mostly made without binders. I wouldn't want to run a
pellet mill with creosote.

Glycerine has emerged as a potential waste. Its value would be more as a
pilot fuel than as a binder. If I remember correctly from my palletizing
days the amount of oil/fat like material you can add to pellets is pretty
small.

Subject: [Gasification] Creosote as Binder???

Can anyone shed light on whether creosote might be used as a "binder" 
for planer shavings and other Kiln dried wood residues for making pellet 
fuel in a pellet mill ? any thoughts on gumming? Normally extruded 
pellet fuel comes out "hot". I understand that the usual method is 
addition of paraffin to bind the pellets (or logs) made from kiln dried 
shavings where the lignins are destroyed. ALTERNATIVELY: Does anyone 
know whether glycerins (especially those left from Biodeisel from WVO) 
might provide binder properties for pellet fuel?

has potential as a fuel. Then maybe what's left after using it as a fuel can
be composted.
