I agree that there is a market for this type of fuel.  Currently there are several MFGs of this stuff.  They wouldn't be in business if they couldn't sell it.  But...I think this is a pretty small niche market compared to cord wood.  I think its gonna end up being a volume thing.  To do this for any type of mass market the bricks will go beyond using scrap material and into real trees.  Why not burn the trees.
Note: I have no facts backing this up...simply my opinion.
