George & Gerry, 

Thanks for that George but we are (like yourself Gerry) from the US past of North America. 

We don't directly sell equipment but rather do a lot of the upfront r&d then work with various entrepreneurs around the globe to adapt the tech. to their conditions, resources, etc., and to help launch them (thru promotion and awareness, and onsite training activities online) so that they can run their own small business, supplying such to their own local and national markets. we subsequently return as learners to gather new insights from the practitioners.. It's a pretty lively network although, w have only a small idea of the total activity now, as  so many of the trainers and producers generally function quite outside internet access as we enjoy it here. 

There are dozens more press designs and a few other material processors being developed  and supplied online by others as well. 

We can happily sell you or own  manuals for how to make and operate a variety of presses and  our two versions of material processers  ( our TMC and the forthcoming Mini TMC) but you may really want to shop around , using such google entries as;  'biomass briquette presses'. for starters.

Please note too, that the kind of briquette process used vastly influences the very different kinds of technology used:
Our own process (as developed by the late Dr Ben Bryant out of  U. Washington (Seattle), involves ambient temperature lots of water and sludgy biomass blended with same or more combustible granular material (sawdust /rice husks/ waste  charcoal crumbs  and dust / paper /&  certain types of carton board  for starters etc etc. The pressures involved rarely require exceed  12 bars ~ 250 psi ( if you know what you are doing) which nicely lends itslef to hand made hand operated pressing and processing equipment at a very local scale ( see our website video for a description of that if you like). While it can be amped up (see Fuego del Sole's revised  25 gang press in Haiti) it maily finds a ready adpatation at the less institutional micro-entrepreneur level.  

This same level of tech can apply to binder added briquettes and such as biochar / char dust briquettes  

When one moves up the energy intensive ladder to lignin melting chipboard density-level briquete pellet or log making technology the ball game changes to far higher level of machine skills capital investment and operating and maintenance skills and resources. The internet is full of these screw augur, rolling cylinder and hydraulic ram driven technologies as well.  Operatgin pressures of 5000 to 9000 psi and temperatures up to 400 deg F are generated in these machines and a large space for blowing drying  and material transfer equipment is required as well. dev finately something more for the urban markets.

Just a  head's up to head you in the right direction, but not really knowing what that is  !
 
Will be glad to exchanage a few emails to help hone your interests, if you lke.

Kind regards,

Dr.  Ostheimer:

   This isn't quite answering your question,  but Nathaniel Mulcahy of World Stove (cc'd) does produce a pelletizing machine for use with his own char-making stove design.   I presume applicable to many stoves and possibly/probably for sale.

Dear Chris and Chrispin,
I work for the USDA Foreign Ag Service and represent the U.S. to the Global Bioenergy Partnership and I collaborate with the Global Alliance for Clean Cookstoves. I would like to learn of there are commercial or non-profit groups in the U.S. that are producing and selling equipment to produce briquettes for cookstoves in the developing world.
Thanks much,
Gerry
