@Tom_Fredenberg ha… of course. basically think of mulch you use outside your house, maybe. more dark redish, much more stringy, wood waste, product. Sawdust, forest debris, bark, often left over lumber. A wet(usually) consistency overall…all run thru a grinder. (wood Hog). A great deal of it used to burn in industrial boilers to create steam, then electricity, lumber yards re-used it for the drying kilns, etc…. recycling back in the early 20th century and still used today in its current form.
