[Stoves] Charcoal from waste - home cooking or other markets? (Re: Crispin, Anand Karve)

There's a lot of activity in the Ukraine - using relatively low cost wood
waste extruders sources from China (Alibaba "pini kay"  )

http://piroliz.org/news/2013-12-23-16-50-12/eng

The briquettes are made first  from raw wood waste - then pyrolysed in a
kiln.  This is an alternative method to pressure forming briquettes from
charcoal dust with starch binder - which might be more appropriate on a
village scale.

I'm currently investigating both methods to see if I can find a cheaper
method of creating the pressures needed-  using solar generated dc power -
 but without using a $3500 machine from China.

I can produce 50kN with a 1000W dc motor (forklift pump motor) and then a
hydraulic 50 tonne bottle jack  ($50 China) to step this up to 500kN.  This
is about 15.5MPa across a 64mm diameter briquette.
