Saw this in FB and checked it out. If your near Northumberland County Pa. and interested, Jeffs recycling in Paxinos Pa. is making these things. I experimented a long time with shredded paper but the mess vrs what you got out of it wasn't worth the time.
They say that a half ton skid of these carboard chip blocks for $240 has the same energy as 1 ton of coal. I can get one ton of coal for $170 so he will have to come down quite a bit to be competative. However once production and sales ramp up, you never know.http://wnep.com/2014/03/07/turning-tras ... ng-blocks/
