Logs in their natural state are quite random shapes, even after selective pruning and thinning.
Also they have bark on them which is seen as a biosanitary and transport hazard.
If logs were preturned in the forest into uniform cylinders it would reduce their transport costs, remove the bark and reduce waste handling problems at the processing destination.
It is likely such enhanced logs would attract a premium price.
The benefit to the biocoal business would be more raw material to process into saleable biocoal.
