[Stoves] pelletized waxed cardboard boxes

[Paul S. Anderson]

Dick,

The    enviro-log.net    website mentions "Waxed Old Corrugated Cardboard
(WOCC)" and give interesting info.     hotlog.com    is under construction.

WOCC certainly has potential as a fuel.  My interest in small cookstoves leads
to the following:

1.  Compressed WOCC products:
The 3 and 5 pound logs are too big for our stoves.  But there is no 
reason that
I know of that the compressed WOCC products could not be made into stick form
(perfect for side-loading stoves) or into chunky pellets (1 to 2 cm 
dimensions,
not the small pellets of pellet stoves).  If I get affirmative info from
Enviro-log company, I will report the reply.  But I suspect that there will be
little interest in making the small stuff.  We will see.

2.  Cut and diced WOCC boxes:
Experimentation will be needed, but perhaps a recycle facility (that 
already has
the large cutters, etc) could send the boxes through the cutter to get strips
that are partially crushed, and then cut again to make the strips into
approximate squares.  Size would be about 2 x 2 cm up to 3 x 3 cm (about 1 x 1
inch), with thickness of the cardboard (but crushed somewhat).  This can be
done at my local recycle facility for paper.  Alternatively, anyone could cut
up a few boxes with a box cutter just to have enough to do testing.  For
side-loader stoves that use stick-type fuel, just cut into strips and 
feed into
the fire area.

The squares could be handled with a shovel, and might make a nice fuel for the
small gasifiers.  The T-LUDs could probably burn this type of fuel very nicely
(to be tested).

So, this is on my list, but other tasks are ahead of it, so I hope others will
consider this fuel option and report it first.
