To produce chips (= chipping) on the trail, full trees (buffer 21 to 24), tree lengths (buffer 22 to 24) or residues (buffer 23 to 24) can be used.
The chipping is a mechanized work and can be executed by a chipper.
A specialized option is a biomass-harvester. This machine fells the tree and directly forms chips out of it (buffer 10 to 24).
