[Gasification] Creosote as Binder???

[Paul Francesco]

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?
