[Bioconversion] News Paper Fireballs

Dear Les and All:

I went through these steps on a small scale to produce paper/trash 
pellets for a DOE contract last year.  I put newspaper down my wife's 
disposal (when she was out) and collected the pulp.  I could hand 
squeeze it to a density of about 0.4 g/ml, about like softwoods - 
adequate for many combustion situations. 

I believe that a compression screw could increase the density to about 
0.6 g/ml with further dewatering. 

Paper is inherently dense - and sinks in water, so density > 1.0.  It 
has already been densified to this level in the paper making process.  
It can incorporate reasonable amounts of other fuel/waste in its fibers 
(including charcoal dust?). 

Could you recommend a simple compression/dewatering screw?
